OIL SEALS
The first true oil seal model was created in Germany in 1927. 12 years later, NOK was established as the first specialized manufactur¬ er of oil seals in Japan. Therefore, the history of oil seals in Japan is in fact the history of NOK. To the extent that the quality of an entire country's oil seals also reflects its advanced industrialization level, NOK has been leading the way for over half a century with superior technology. NOK has consistently established leading technologies based on cutting-edge theories. For instance, in 1959, the company was the first to expound a theory
of lubrication relating to friction and the sealing of oil seals. Such technological innovations and unmatched quality control has enabled NOK to provide reliable,
functional products.
NOK also has been instrumental in developing various research and development areas, including electronics, nuclear power, and polymer chemistry, all based on our accumulated technical knowl¬
leading technologies. At present, NOK is actively researching and developing new products that will herald the future for the fields of chemical electronics, optical elec¬ tronics, and biotechnology.
edge.
Companies in various industries worldwide depend on the knowhow NOK has cultivated through decades as a market leader. In keeping with this trust, and to respond to every individual need, we at NOK are dedicated to fur¬ ther improving our technologies and developing next-generation seal products.
As we continue to strive to meet From component parts to sub¬ assemblies to complete systems, the company's manufacturing business has continued to grow since its beginning.
Oil seals are not only the mainstay of NOK, but are also important foundations for NOK's various
our goals of manufacturing oil seals with even higher levels of functionality and precision, we ask for the continued support of you, our customers.

Two oil seals having identical contact pressure distri¬ butions were produced using these two lip materials. Since it is generally difficult to measure an air intake rate on an oil seal, the fluid transfer rate is measured using a reversed seal orientation. Thus, oil is now on the "air-side ' of the seal, and is transferred under the seal lip via the seal's pumping action. Scenario (a) in Figure 4 shows a normal seal installa¬ tion, i.e., when air is forced toward the oil side. Scenario (b) shows that oil is transferred toward the air side because the oil seal is installed in 'the reverse
direction.
Figure 4: Normaland Reversed Oil Seal Orientalion
The two critical elements described above that exert control over the seal's performance, the lubrication characteristics and sealing mechanism, are in a deli¬ cately controlled balance through two design factors: the material and shape of the lip. Therefore, in view of these material science considerations, it is necessary to keep in mind that the circulating oil flow must be restricted to within the lip contact area, and that the average film thickness under the seal lip must be con¬ trolled. NOK has put considerable effort into developing lip materials specifically based on the above concepts, and has developed oil seals that can respond to various demanding conditions. NOK will continue to concentrate on providing prod¬ ucts of unsurpassed performance and quality through our ongoing development activities.
(1)Correct Orientation
//////////////////////////// (2) Reverse Orientation
(Air side)
//////////////////////////// Through the reverse installation (b). the seal's ability to pump oil was quantified by running the shaft and measuring the resultant oil flow rate. As a result, lip material A was easily identified as more effective in pumping fluid from the air side toward the oil side than lip material B. This was true only when the shape of the lip is not considered (or the same). Even when the lip materials were identical, the pump¬ ing ability changes according to the profile of contact pressure distribution; for instance, by changing the shape of the lip.

A. WHAT IS AN OIL SEAL? Simply stated, oil seals are components of a machine that seal lubricants. Lubricants are used in the friction-producing areas of a machine to ensure smooth movement and long life, and oil seals are used to prevent this lubricant from leaking through "bearing clearances" of the machine. With advances in mechanical engineering, it has become necessary to prevent the leakage of not only lubricants but also water or chemicals, as well as preventing the entry of dust and dirt into the machine. Oil seals are used to perform both functions.
'lite function of an oil seal is easily understood by examining a familiar example:the automobile. Figure 2 shows oil seals used in automobile engines. In such engines, the reciprocating motion of the pistons is converted into the rotary motion of the crankshaft by the connecting rods. The crankshaft is supported by metal bearings. To lubricate these metal bearings, and other areas where metal and metal slide against each other, engine oil is filled in the oil pan. Since the oil pan is secured to the crank case, "bearing clearance" is needed between the fixed crank case and the rotating crankshaft. An oil seal is a sealing device that prevents the leakage of engine oil from the bearing clearance between the rotating crankshaft and crankcase, or the bearing clearance between a reciprocating shaft and crankcase.
0 rings, lip packings, gland packings, and mechanical seals function in similar ways to oil seals, as shown in Figure 1. Oil seals are most often used in rotating

Function The seal lip has the cross-sectional profile of a wedge, and it presses down onto the shaft surface to seal in fluid. The seal lip is made of a flexible elastomer and is designed to maintain stable shaft contact and sealing even with machine vibration and fluid pressure fluctuation. A garter spring adds to the radial load and helps keep the sealing edge in proper contact with the shaft.
A dust lip is an auxiliary spring-less lip. and acts to prevent dirt ingestion. The seal OD creates a press-fit to the housing bore, thus retaining the seal and preventing fluid escape. An internal metal case provides a solid backbone for rigidity.

B. THE SEALING MECHANISM OF AN OIL SEAL How do oil seals actually seal fluid? Due to the continuing efforts of many scholars and
researchers, the fundamental sealing mechanism of oil seals has been almost completely illuminated. NOK announced a sealing theory in 1959, followed by the release of numerous technical publications to the Japan Society of Mechanical Engineers, the Japan Lubricator Makers Association, the Society of Automotive Engineers in the United States (SAE), and the British Hydrodynamics Research Association (BHRA). This theory has earned an excellent reputation among researchers and related industrial societies as being an accurate representation of seal function. In this chapter, the lubrication factors and sealing mechanism of oil seals are briefly described based on the NOK sealing theory.
ÿLubrication Characteristics Oil seals used in machines play a major role in sealing fluid, whether the machine is stopped or a shaft is in motion. The frictional force of the lip area is small, and there is little wear. What lubrication factors of the seal lip's contact edge affect the life of an oil seal? These factors are explained in view of a seal's macroscopic phenomena. To understand these lubrication factors, it is important to evaluate the seal's frictional properties. For this reason, we placed seals in a test machine, as shown in Figure 1, and measured rotational friction forces by turning the shaft under various conditions.

processing technology. Underneath the very narrow lip edge, oil is continually circulated from the air side to the oil side, and then from the oil side to the air side. thus lubricating the sliding surfaces and limiting wear. Theoretical studies have revealed that the sealing mechanism is determined by minor "irregularities" in the sliding surface, and by how the pressure is distributed at the contact area. Here, the sealing mechanism of oil seal is briefly described through macroscopic phenomena.

In Figure 2. the positive slope area of the frictional properties has been explained by the lubrication theory. Under such lubrication conditions, the frictional property of seals is governed by the viscosity of the fluid and the shaft's linear velocity (and is also identical to the frictional property of the bearing), and the resultant oil film present underneath the lip edge. in other words, the oil seal's lip and the shaft slide against each other with an intervening film of oil, thus reducing wear.

The TR10 value is used to determine the low temperature limits. TR is an abbreviation for"temperature-retraction," as defined in ASTM D1329. TR represents the recovery properties during low temperatures,
\\
\
and nearly equals the recovery properties of
rubber-like elasticity. The TR10 value indicates the temperature when a given strain is recovered by 10%. Figure 1 shows a typical TR curve. T: Temperature ( C)

of the lowest allowable tempera¬ ture. Under actual use conditions, even if the temperature is lower than the TR10 value, the temper¬ ature at the sealing edge increas¬ es due to friction immediately after start-up, allowing rubber-like elasticity to be recovered and thus retain good sealing performance.
The lip of the oil seal flexes only a few percent when the run-out of the shaft is only a few percent.
17
However, even if the temperature is higher than the TR10 value. leakage may occur if the shaft run-out is too severe for the lip to follow properly. Thus, it is dan¬ gerous to determine the allowable temperature of oil seals solely on the TR10 value. These and other factors mentioned should be taken into consideration.

proper raw materials or compounding chemicals, and apply appropriate compounding techniques. At NOK. we develop high-quality raw materials and compounding chemicals, combined with research about the effect of each material on the sealing function, in order to create an optimal material for oil seals. Furthermore, we apply the results of this research and technology to manufacture better lip materials.
Each lip material is designed for outstanding sealing performance and the best balance between each property inherent to a raw material. To obtain well-balanced lip materials, it is vital to select Table 3: Types and Primary Uses of Typical NOK Lip Materials

The various degrees of resistances and the tempera¬ ture ranges shown in Tables 2 and 3 are for informa¬ tional purposes only. Users should carefully read Chapter li "NOK Oil Seal Application Guide" and Chapter J "Oil and Chemical Resistance of NOK Up
Materials." To safeguard the function of the oil seal, careful atten¬ tion is required regarding the application's operating temperatures, as temperature directly affects the both
the seal and the fluids. Rubber is sensitive to changes in temperature. A change in rubber at higher temperatures produces a chemical change in which elasticity is lost because the high polymers of the rubber are excessively cut or bonded due to heal, oils, chemicals or ozone. Therefore, the proper working temperature can be determined by the correlation between temperature and time. For example, relatively high temperatures may be used for short periods of time. Conversely. lower temperatures may be used for longer periods of time. Another change in rubber properties at very low tem¬ is hardening caused by less active polymers. This reversible phenomena is dependent on tempera¬ ture only. The normal rubber-like elasticity of an oil perature
seal is recovered when the ambient temperatures return to normal.

— The Function of a Garter Spring A garter spring increases and maintains the pressure of the sealing lip on the shaft. Since garter springs used in oil seal have the characteristics shown in Figure 2, it is possible to obtain the load necessary for good sealing with little elongation. As shown in Figure 2. even if a garter spring is elongated to some extent, the spring load does nqt change significantly. The length of a garter spring in an oil seal is determined by considering the proper amount of elongation required to ensure that it can function properly within the working range defined in Fig. 2.

E. NOK OIL SEAL APPLICATION GUIDE To ensure optimal performance, it is necessary to select the appropriate oil seal type and material for the actual operating conditions.
This chapter describes selection process and permissible temperature ranges for each type of oil seal listed in this catalog. If the oil seal you need (type, material, or dimensions) is not listed in this catalog, please contact us regarding customized products.
Selection Process Use the following steps to select your oil seal.
.
1 Select the Seal Type
Select the proper seal type per Figure 1 "Flowchart for Seal Type Selection" on pages E-4 and E-5.
2. Select the Seal Lip Material Since lip materials for catalog products should be selected according to the appropriate condi¬ tions for each oil seal type (see Table 1 "I.ip Materials by Oil Seal Type" ), please refer to Table 3 "A Guide to Permissible Working Range of Standard Oil Seals' (on pages E-6 and E-7) and Table 4 "A Guide to Select the oil seal type in accordance with Fig. 1 "Flowchart for Seal Type Selection" on pages E4 and E5. "A Guide to the Allowable Operating Conditions of General Oil Seals" (pages E8 to Ell), as well as Chapter J "Oil and Chemical Resistance Ratings of NOK Lip Materials." 3. Select the Metallic Materials The metallic materials for garter springs and cases should be selected by the appropriate oil seal type, same as lip materials. Table 2 shows the appropriate metallic materials by oil seal type. Please refer to Table 4 "Types and Applications of Garter Spring and Case Materials (page D-7).
4. Select Seal Dimensions Check whether the dimensions of the oil seal you want matches the shaft diameter, housing diameter, and width of the relevant area by refer¬ ring to Chapter H "Type and Size List of NOK Seals."
Please consult us before using NOK oil seals in aircraft or nuclear power equipment. The oil seals listed in this catalog are not designed nor manufactured to be used in medical equipment, and should not be used in medical equipment used for transplant surgeries or in applications that come into contact with bodily fluids or living tissue.

The permissible temperature of a lip material varies with the operating conditions of the actual equipment used.
Temperature limitations for the Slype oil seal, which is a typical oil seal, are summarized for your reference. Please note that the temperature at (he lip of the T type seal rises twice as much as the S type, and that the temiierature rise of the V and K types is the same as that of the S type.
Table 5 shows an example in which the usage time at
the maximum normal temperature is within 30% of the total operating time. Titus, if the working time at the maximum normal temperature exceeds 30% of the total operating time, reduce the permissible temperature (T) by 20 "C.
To select the proper lip material for an oil seal, it is necessary to estimate the approximate temperature at the seal lip edge of the oil seal (To). This temperature can be estimated by determining the maximum normal temperature of the fluid near the oil seal (Ti), and the increased underlip temperature generated by the friction between the shaft and lip (73 (Refer to Fig. 3.) The temperature at the sealing edge (To) can be given by the expression (1) below.
For gear oil or high-viscosity silicone oil, the frictiongenerated heal at the lip (71') is 1.5 times the value shown in Fig. 3. For grease, the friction-generated heat at the lip is 3 times that shown in Fig. 3.

2. Shaft Design Concepts The material, hardness, and machining method of the shaft has a significant influence on the performance of the oil seal. Design specifications for the shaft need to be determined after careful examination of all relevant
factors. (1) Shaft Material Steels for machine structural use, are suitable. However in case of cast iron or plastic, refer to Table 5 "Notes on Usage" before selecting one of these materials.
(2) Shaft Hardness The surface of the shaft with which the sealing lip of an oil seal comes into contact needs to be at least 30 HRC for the following reasons: 1. The shaft surface will nol be easily scratched or dented. 2. An appropriate surface finsih can be easily
machined. 3. The shaft (especially a hollow shaft) will nol deform easily.
Dents are easily overlooked, however, and ilis impor¬ tant to take care that the shaft is nol damaged by conlad during shipping and assembly. Table 5: Notes on Usage
Shaft Material
Notes on Usage
Cast Iron
Pinhole porosity is likely to appear in cast iron shafts. II the size of the pinhole is larger than 0.05 mm, and the seal lip rides in or around this pinhole, leaks may occur. This is due lo a localized and rapid loss of shafl contact to the seal lip. If cast iron shafts must be used, NOK recommends using nodular graphite casl iron shafts.
Plastics
Ceramics
NOK does not recommend using plastic shafts. II is difficult to insure proper hardness
and surface finish, and heat dissipation is poor due to low heal Iransfer qualities.
Although ceramic shafts may be used in chemical equipment, ceramic shafts are not recommended for use with oil seals. The unique surface roughness of ceramics accelerates seal lip wear, significantly reducing the life of the oil seal. Consult us before using ceramic shafts.
For use with J type (PTFE) seals, the shaft surface under the seal lip needs to be as hard as 50 lo 60 HRC, as the J type oil seal is more likely lo increase wear on the shaft compared to other oil seals. The J type oil seal is used for fluids with poor lubricity, such as chemicals or solvents, and in high temperature areas or under poor lubrication conditions. Therefore, a shaft with a hardness of only 30 to 40 HRC will quickly wear out.
(3) Shaft Finish and Machining Method Generally, the shaft roughness directly affects the degree of seal leakage and wear (this varies according to shaft speed and oil quantity) regardless of the shaft hardness. Therefore, it is important to use shafts with the surface finish roughnesses listed in Table 2. For rotating shaft oil seals, special attention is needed. If machining flaws run continuously along the shaft, leaks may occur even if the surface roughness of the shaft is within a range of 2.5 to 0.8mm Rz (excluding
T4 type and QI.FY type oil seals).
F
The following section discusses proper and improper machining methods (i.e., introducing machine lead onto the shaft through poor machining practices).
Proper Shaft Machining Methods Ground Finish Plunge grinding produces non-continuous machining striation markings that are at right angles to the shaft centerline, as shown in the photograph on the right. This is the optimum finish technique for best seal lite and performance. After plating with hard chromium to improve resistance to corrosion and wear, be sure to plunge-grind the final surface.

Minimize Shaft Wear * When the oil contains high levels of silica or alumina, shaft wear can be reduced by changing the oil at appropriate intervals. In addition, hard chromium plating of the shatt or using hard chromium plated sleeve shafts is recommended.
A shaft may experience wear even it it is treated via induction or carburizing hardening processes. This is primarily due to dust, earth and sand, or silica (Si02) or alumina (AI203) contained in deteriorated oil. These minute foreign particles can enter into the contact area of the sealing lip either from the air or oil side. To protect the shaft from wear caused by particles from the air side, NOK recommends using a dust seal together with an oil seal, or selecting an oil seal with higher dust resistance.
p Grindstone Dressing
-
— ---ÿ
ÿ
Take care when dressing the grindstone for plunge ground finishing. If the grindstone incurs directional lead during the dressing, the lead will transter to the shatt. NOK recommends roller dressing. If single-point dressing is unavoidable, use a slow feed rate and be sure to spark-out during grinding.

F-5
Improper Shaft Machining Methods Lathe Cut Finish lathe finishing is very distinctive: a roughness curve shows continuous rows of well-shaped triangular peaks and valleys spiralling around the shaft. These spiral valleys can continue from the inner side of the oil seal, through the sealing lip contact area, and to the air side, causing sealed fluid to leak through the valleys via a

.
"screw-pump" action.
Super-finishing
Super-finishing creates a herringbone-like texture, and reduces roughness compared to other finishing meth¬ ods. However, this texture also causes seal leakage through the presence of machine lead, which can over¬ power a seal and pump oil to the air side. in some cases, this herringbone-like texture can cause premature wear on the seal lip.
Roller Burnishing Roller burnishing is generally performed after a lathe cutting operation. The burnishing will not remove the substrate machine lead produced by the lathe, which could cause leakage. Roller burnishing is also prone to producing a loo-smooth finish, causing the oil film to become too thin, resulting in increased friction and premature seal wear.

Emery Paper Finishing
After lathe machining, finishing the surface with emery paper is the easiest and most widely accepted method. However, finishing by moving the emery paper axially produces a herringbone lead texture, causing leaks to occur (similar to super finishing).

ÿ Housing (4) Shaft Chamfer If there is a sharp corner at the shaft's end, the seal lip will bo damaged when the oil seal is installed over the shaft, thus causing a leak. Also, if the shaft is not prop¬ erly chamfered, the sealing lip might get caught on the corner as shown in Fig. 4, causing lip "turn-under" and possible garter spring ejection. Therefore, the shaft should be properly chamfered as shown in Tables 3 and 4.
Figure 4: Lip "Turn-Under" and Garter Spring Ejection
The housing is the area where a bore recess can receive and retain a seal. Table 6 shows the most desirable design characteris¬ tics for housing bores, and Tables 7 and 8 show the shapes and sizes of various housing bores.
1. Housing Design Specifications Design specifications for housings are shown in Table 6. Refer to Table 10 for MG type, Table 11 for 0 type, and Table 12 for VR and 7. type oil seals. 2. Housing Bore Configuration The shape and size of a housing bore needs to be determined according to the type and size of the oil seal to be used. Design a housing bore based on the following:
(1) Standard Oil seals
For standard oil seals (with shafts up to 300 mm in diameter), the shape and size of the housing hole varies depending on the pressure in the application.
Shalt Inserted This Direction
Non-Pressurized Applications (Ma*. 0.03 MPa (0.3 kgl/cm*)
The shapes and sizes of housing bores in non-pressur¬
ized applications are shown in Table 7. (5) Shaft Key Ways and Splines
Even if the shaft is properly chamfered per Tables 3 and 4, the seal lip may be damaged if there is a key way or spline on the shaft surface which the lip contacts during installation.
Figure 5: Cover Design for Key Ways or Splines
Round to 0.3
If a key way or spline must be used on the shaft surface that will pass under the seal's lip during installation, make the nominal diameter of the key way or spline 5 to 15mm smaller than the diameter of the shaft's seal journal so that a cover may be used, as shown in
or chamter
Figure 5.
(6) Miscellaneous If a shaft's bearing journal is the same diameter as the shaft's seal journal, the shaft will be scratched from bearing installation, and thus cause a leak path under the seal lip. Instead, design the shaft's bearing journal to be larger than that of the seal journal, thus avoiding shaft damage in the critical seal lip area of the shaft

MG Type Oil Seal Design specifications of the housing bores for MG type oii seals are shown in Table 10. Since no reinforcing metal case is used in an MG type oil seal, the seal is installed by cutting the seal at one point and butt-jointing the cut ends, which makes it difficult to obtain the proper retention strength.
Therefore, the housing bore must be designed so that the oil seal sits at the correct position and is secured by pressure from both sides.

3. Housing Design Concepts The material. roughness. size, and shape of the hous¬ ing bore will affect the performance of the oil seal. Determine the design specifications after careful con¬ sideration of these factors. (1) Housing Material For steel or cast iron housings, use either rubber OD or metal OD seals. Since light alloys or resins generally have high coefficients of thermal expansion, the size of the housing hole increases as the temperature increases. For metal OD oil seals, leakage may occur in the press-fit area, or the seal itself may become dislodged. If light alloy or plastic housings must be used, use rubber OD
(4) Housing Bore Design If excessive weight or pressure is placed on the oil seal, it may become dislodged. No special care is needed if there is no inner pressure on the oil seal (max. 0.03 MPa (0.3 kgf/cm-'). In applications where the pressure is 0.03 MPa (0.3 kgf/cm-) or larger. design the housing so that it secures the oil seal axially. The shape and size of the housing bores are shown in Table 8 on page F-9. You can select either configu¬ ration O or 0 in the table. Configuration © allows easy installation and removal of the oil seal. If a snap ring must be used, round (blend) the snap ring groove edges of the bore as shown in ©.
seals. (2) Surface Roughness of Housing Bore (inner diameter surface) Oil seals prevent leakage by maintaining contact between the sealing edge and shaft and also by obtaining a proper fit to the bore. Thus, care is needed when machining the housing hole. A very rough inner housing surface will create a leak path past the seal. Refer to Table 6 on page F-8 for pro|>er roughness levels.
(3) Dimensional Tolerances of Housing Bores At NOK. we define outside diameter tolerances for oil seals based on J IS H8 for oil seals with 400 mm or smaller nominal outside diameters and J1S H 7 for oil seals with 400 mm or larger nominal outside diameters.
IfJISII8or JISH7 standards are not used, seal installation be difficult, cause damage, or even fail to be retained during operation.
(5) Split-Typo Housing Avoid using a split-type housing for the following rea¬ sons:
© Leakage may occur from the split line area.
® Seal displacement may occur at the split line area.
® it may be difficult to ensure proper roundness of the housing bore.
©
Misalignment may occur between the shaft and
housing hole. Items © and @ result in leaks at the split line area. and item © results in leaks at the sealing lip. If a split-type housing must be used, machine the hous¬ ing so that it does not misalign and become ovalshaped. and then use a rubber OD seal in the preassembled housing.

(6) Improper Housing Bore Designs Figure 3 illustrates two improper housing designs. For case O, since stamped steel is used, the hole sur¬ face is apt to be tapered and the inside diameter or roundness will vary, causing the oil seal to leak or even
become dislodged. For the housing design in 0. the housing may be installed off-center, as it uses a combination of screws. Do not usea screwed-in housing.

G. NOK OIL SEAL HANDLING GUIDE Even if you correctly designed or selected the shaft and housing into which the oil seal is installed, rough handling or assembly of the oil seal may result in the oil seal being unable to function as intended. This chapter discusses proper handling of oil seals during assembly and replacement. Before using an oil seal, read and follow the rele¬ vant instructions.
ÿHandling NOK's Standard Oil Seals Use the following as guide to proper seal handling.
1. Packaging Oil seals are packaged in bags, rust-preventing paper. or corrugated cardboard boxes, depending on the size or quantity, lite packaging is necessary to protect the oil seal against rust, damage, and foreign matter. Only open the package immediately before use. 2. Storage (1) Storage Precautions Follow these instructions when storing oil seals. O Do not open the package until needed, as the oil seals may become contaminated or damaged. 0 Do not expose the oil seal to direct sunlight for extended periods of time. Ultraviolet rays may has¬ ten the deterioration of rubber. ©Do not place the oil seal in locations where it may be exposed to excessive moisture. Rust can form on the external metal or garter spring of the oil seal. ©Do not place the oil seal near heal sources, such as a boiler or stove. Heat accelerates the deterioration of
3. Protect the Shaft and Housing Take care not to damage the shaft and housing before assembly, as leaks may occur. Use a carrying jig to prevent the finished surfaces of the shaft and housing from contacting other objects, as indicated below. Figure 1shows a storagejig for housings. Each housing is placed so that it leans against individual partitions to prevent damage. This jig is made from plastic to prevent the metal part from being scratched. Figure 12 shows a storage/transport cap jig for shafts. Placing this plastic cap over the shaft prevents the shaft from beingdamaged. Figure 1: Housing Storage Jig

dangling the oil seal using a cord. The oil seal may be deformed, or its sealing edge may be damaged. ©When storing the oil seal after opening its package. take care to protect it from rust, as well as foreign particles such as dust and sand. ©Avoid excessive shock during handling or transit to prevent deformation of the oil seal or dislodging the garter spring.

•The storage periods shown on the left are applicable to products sealed in standard packaging and stored in a cool dry place away from direct sunlight. • The indicated storage periods do not account for rust formation on the metal jwrts of bonded seal products, since rust is largely influenced by the storage environment. • Before using an oil seal that has been kept in storage for an extended period of time, check that it is free from rust. • A white powder may api>car on the surface of rubber products (known as "bloom phenomenon" ). This does not affect oil seal performance.

4. Preparation Before Assembly (1) Oil seal
ODo not use an oil seal that has dust or sand on it, as leakage may occur.
0 Do not scrape the sealing edge of the oil seal with nails or other hard objects. The sealing edge is the most important part in determining oil seal perfor¬
mance.
© For an oil seal having two or more lips, such as the T type and K type oil seals, apply mineral based lithi¬ um grease (for example, Sealube SI made by NOK) betweenthe lips to lubricate the lips. (See Fig. 3.). 0For an oil seal having only one lip, such as the S type, V type, and TCK type oil seals, coat the seal lip edge with grease to lubricate the lip. For recommended greases, refer to page K-ll. Figure 3: How to Apply Grease (A) Correct
Apply the grease so that it does not overflow past the lip. as shown in (A).
(B) Incorrect
Applying too much grease, as shown in (B). may cause overflow during assembly that may be mistaken for leakage.
(2) Shaft and Housing
O Check that the shaft surface and the housing bore
© Check that the inner surface of the housing bore
are free of rust preventatives, dust and grit. If these impurities exist, clean thoroughly to remove. If oil or gasoline is used for cleaning, carefully wipe the area dry. Also, spraying compressed air is effective, as it cleans areas that are not readily visible. Residual oil or gasoline on the shaft or the housing bore can result in the oil seal swelling to an incorrect size, which may cause leaks.
and the chamfered area, as well as the shaft end and the shaft surface into which oil seal is inserted are free of defects and burrs. Remove any irregularities with emery paper to prevent damage to the sealing edge or outer surface during assembly.
0Check that the shaft surface that the sealing edge will contact is free of defects and rust, thus prevent¬ ing leaks from those causes.

(2) Assembly Into a Split-Type Housing avoid using a split-type As mentioned on page housing if possible. If a split housing must be used. first assemble the housing, then install the seal in order to prevent cocking the seal.
6. Installing the Seal Onto the Shaft © Apply a thin coating of lubricant or mineral oil based lithium grease (for example. Scalube SI made by NOK) to the shaft surface and the chamfer area. The seal should be smoothly inserted onto theshaft. Take care not to cause lip turn-under during this operation.
beaks can occur at the mating surface areas of the split housing. Apply a coat of liquid gasket sealant to the split area to prevent this leakage.
©Align the center the of the seal with the shaft centerline, and carefully insert the shaft into the oil seal.
(3) Liquid Gasket Sealant
©When
When a metal 01) seal is used, it is necessary to apply a coat of liquid sealant to prevent the bore II) surface from developing flaws during oil seal replacement, or when a metal OD seal is used and the application is subjected to internal pressure. Observe the following precautions when using sealants.
©Apply a thin coating of lite sealant to the bore II) surface of the housing, and wipe off any excess. Leakage can occur if the lip or the shaft surface is contaminated with sealant.
installing a pre-assembled housing and seal onto a shaft, or inserting a long shaft into a prcassembled seal/housing, the seal lip can be damaged due to shaft contact during this awkward operation. See sketch (A) in Figures 11 and 12. Avoid this damage by installing the seal only after the shaft and housing are assembled. If this is impossible, use an installation guide for the housing or shaft, as illustrated by (B) in Figures and 12.
0 Full-curing or extremely
strong sealants require excessive force to remove the oil seal, usually resulting in damage to the housing. Always use
semi-drying liquid gasket sealant.

8. Cleaning and Painting ©Cleaning the machine with oil or gasoline may cause the lip material of an exterior seal to swell, resulting in reduced seal performance. 0 When painting the machine with an exterior seal, use care not to get paint on the oil seal or the shaft surface.
ÿHandling NOK's General Oil Seals The following explains how to handle general oil seals. Handle D-type oil seals in the same manner as standard
oil seals. J-Type (PTFE) Oil Seal The sealing edge of a J type seal is more susceptible to installation damage than seals with standard synthetic rubber lips. Observe the following precautions when mounting J type oilseals onto the shaft.
O Check that the shaft end is free of burrs or other defects. © Use an installation jig when there are keyways or splines on the shaft. (Refer to Fig. 8 on page G-8.) ©Insert the shaft in the direction indicated in Fig. 14.
OC-Type Oil Seal The seal lip and press-fit area of OC type seals are "inside out" (reversed) relative to those of standard oil seals. Nevertheless, handle this seal in the same manner as standard oil seals.
The lip is located on the outer circumference. Protect the outer peripheral lip during transit or storage. QLFY-Type (With Integral Shaft) Oil Seal The QI.FY type seal has an integrated shaft (known as a unitized design). Mount this oil seal as a one-piece structure.

WTieWTT,e Nitrile rubber (NBR) oil seal ÿHandling of WTT Type •The WTT Type oil seal issecured with a lightening collar band at its cut point. Any mounting diameter can be selected. •The maximum mounting diameter is 1500 mm. and seven mounting lengths arc available (35. 40. 45, 50, 55, 70. 75 mm). (For your reference, the product sixes currently available are shown on page H-94.) •The WTT Type oil seal cannot completely prevent the entry of rolling fluid or cooling water. Provide a drain at the bottom.
•Position the bolt for the collar band at a 45degree angle from the drain. Example TÿttriogCoU'Mfvl WTTTypo
The WT Type oil seal cannot completely prevent the entry of rolling fluid or cooling water. Provide a drain at the base.
•When ordering, please indicate the NOK part number and the relevant dimensions. •Check the Guide to Allowable Operating Conditions on pages E-10 and E-ll for relevant information on the seal selected before use.

I. SEAL LEAKAGE TROUBLESHOOTING GUIDE ÿCauses of Seal Leaks
Figure 1: The Two Points of Origin of Seal Leakage
If oil leakage is discovered, first determine the point of origin of the leak. The leaks may not have originated from the oil seal, and residual oil or grease on the seal itself can also be mistaken for a leak. Seal leaks are divided into two groups: leaks from the sealing lip and leaks from the press-fit area of the hous¬ ing, as illustrated in Fig. 1. Typical causes of each group of leaks are shown in factorial diagrams (Figs. 2 and 3). Examples of improper diagnosis is discussed on page 1-8.

J. TECHNICAL DATA Frictional Torque of an Oil Seal The frictional torque of an oil seal can be expressed by equation (1).

increases.
The coefficient of friction (f) is determined by many factors, but it generally means dynamic friction under lubricated conditions, and can be expressed by equation (2).
f =$>(// ÿu-b/Pr)U3
The linear shaft speed also influencesfrictional torque. Figures 2 and 3 show the relationship between shaft speed and frictional torque.

/i
It becomes evident that the coefficient of friction (f) for a specific oil seal is influenced by the viscosity (m) of the sealing fluid and the linear shaft speed (u). Figure 1 shows the relationship between frictional torque and oil temperature by oil type. Frictional torque decreases as the oil's viscosity decreases. Also, frictional torque is inversely related to the oil temperature, since oil becomes lessviscous as oil temperature increases.

Frictional torque decreases as shaft speed increases. This is because as the shaft speed increases, Ihe grease temperature increases due to the heat generated by friction, thus decreasing the its viscosity and the overall frictional torque.

Service Life of an Oil Seal 1. Lip Material Degradation Material degradation consists of hardened or softened rubber, cracks, or taking a set. The sealing ability of an oil seal is reduce or eliminated when the lip contact area is hardened or cracked, or the lip-to-shaft interfer¬ ence is decreased.
The failure modes and ultimate service life will vary according to the usage conditions, including operating, environmental, and lubrication conditions. The following will discuss the degradation of lip mate¬ rialsand lip wear (causing a loss of lip-to-shaft interfer¬ ence), which are responsible for the most common oil seal failures.
This degradation often occurs as a result of a chemical reaction between the rubber and the scaling fluid, or a substance intermingled with or dissolved in the sealing fluid. Generally, degradation advances rapidly as the oil temperature increases, shortening the service life of the oil seal. Figure 5 shows the service life of various oil seal mate¬ rials vs.the temperature at the lip contact area (for ref¬ erence only).

2. The Effects of Lip Wear
When there is sufficient lubrication, an oil seal continually circulates oil underneath the lip, thus minimizing lip wear. Lip wear is accelerated by a lack of or degradation of the lubricant, foreign matter trapped in the lubricant, or the entry of external dust under the main lip. Figure 6 shows the relationship between the quantity of lubricant supplied to the lip contact area and the resulting lip wear.
Lip wear increases as the lubricant quantity decreases. However, lip wear actually progresses faster in the presence of a very small amount of lubricant than in the complete absence of lubricant.
Lip wear causes lip-to-shaft interference to decrease, thereby decreasing the seal's ability to compensate for shaft eccentricity. Therefore, the life of a seal with respect to lip wear expires when the lip interference can no longer follow an eccentric shaft (shaft run-out). Figure 7 shows an example of the shaft eccentricity limits of a worn oil seal. Leakage occurs when the Up interference value falls below approximately twice the shaft eccentricity (shaft run-out). Since the progress of lip wear is largely influenced by the quantity of lubricant or other environmental conditions, such as the presence of foreign matter in the lubricant, the performance of oil seals varies according to the actual
apphcation conditions.

How to Read the Table The test method used are in accordance with J1S K 6258 "Testing methods of the effect of liquids for vulcanized rubber" and J1S K 6253 "Hardness testing methods for rubber, vulcanized or thermoplastic". The table displays the test temperature and time, and the post-test changes in hardness and volume.
Ratings of NOK's Lip Materials
The following data is a summary of material test results. It shows the resistance of each lip material to
various lubricants and chemicals. After selecting a preliminary lip material in Chapter E. please verify its compatibility with the lubricant or chemicals to be used.
Hardness and volume change data indicate the post-test change in hardness against the pre-test hardness, and the post-test change in volume against the pre test volume of the test piece, respectively. Plus (+) indicates that the hardness or volume increased after the test, while minus (-) indicates that the hardness or volume decreased after the test. The absolute value is inversely related to the oil or chemical resistance of the material. The resistance of each lip material is determined by assuming that it is used for 500 hours continuously at the listed test temperature, and based on the indicated lest results. Symbols in the "Material Resistance Rating" column are as follows: @ : Good resistance O : Resistance, except in special cases* A : No resistance, except in special cases* X : No resistance tti: Consult NOK before use. In most cases, the stability of the lip material can be determined by consulting the hardness change and volume change data; however, some materials may be classified as A or X despite their small hardness or volume change values. Such classifications are based on other considerations and do not contradict the above-mentioned general principles. For the classification of oil types, refer to the "Lubricant Brand Guide" published by the Lubrication
News Agency. Please refer to the guide for the properties of each oil type.
There are cases in which an inorganic acid, organic acid, alkaline acid, or inorganic salt should not be used due to environmental conditions. Please consult with us before use.
