CAT. No. E1102e
Introduction to Revised NSK Rolling Bearing Catalog (CAT.No.E1102e) We want to thank you for your interest in this edition of our Rolling Bearing Catalog. It has been revised with our customers in mind, and we hope it fills your needs. Recently, technology has been advancing at a remarkable pace, and with it has come a host of new products in many fields including computers, office automation, audio-visual equipment, medical equipment, and many others. These striking innovations present a challenge to bearing manufacturers since there are ever increasing demand to offer bearings with higher performance, accuracy, and reliability. Manufacturers of diverse equipment have many different bearing requirements including higher speeds, less torque, less noise and vibration, zero maintenance, survival in harsh environments, integration into units, and many more. This catalog was revised to reflect the growing number of NSK products and certain revisions in JIS and ISO and to better serve our customers. The first part contains general information about rolling bearings to facilitate selection of the most appropriate type. Next supplementary technical information is provided regarding bearing life, load ratings, limiting speeds, handling and mounting, lubrication, etc. Finally, the catalog presents extensive tables containing most bearing numbers and showing dimensions and pertinent design data listed in the order of increasing bore size. Data in the table are given in both the international Unit System ( SI) and Engineering Unit System (Gravitational System of Units). We hope this catalog will allow you to select the optimum bearing for your application. However, if assistance is required, please contact NSK, and the company’s engineers and computer programs can quickly supply the information you need.

1.TYPES AND FEATURES OF ROLLING BEARINGS 1.1 Design and Classification Rolling bearings generally consist of two rings, rolling elements, and a cage, and they are classified into radial bearings or thrust bearings depending on the direction of the main load. In addition, depending on the type of rolling elements, they are classified into ball bearings or roller bearings, and they are further segregated by differences in their design or specific purpose. The most common bearing types and nomenclature of bearing parts are shown in Fig.1.1, and a general classification of rolling bearings is shown in Fig. 1.2.
1.2 Characteristics of Rolling Bearings Compared with plain bearings, rolling bearings have the following major advantages: (1) Their starting torque or friction is low and the difference between the starting torque and running torque is small.

Furthermore, different types of rolling bearings have their own individual advantages. The features of the most common rolling bearings are described on Pages A10 to A12 and in Table 1.1 (Pages A14 and A15).

(2) With the advancement of worldwide standardization, rolling bearings are internationally available and interchangeable. (3) Maintenance, replacement, and inspection are easy because the structure surrounding rolling bearings is simple. (4) Many rolling bearings are capable of taking both radial and axial loads simultaneously or independently. (5) Rolling bearings can be used under a wide range of temperatures. (6) Rolling bearings can be preloaded to produce a negative clearance and achieve greater rigidity.

DESIGN, TYPES, AND FEATURES Contact angle α
SINGLE-ROW ANGULAR CONTACT BALL BEARINGS Since these bearings have a contact angle, they can sustain significant axial loads in one direction together with radial loads. Because of their design, when a radial load is applied, an axial force component is produced; therefore, two opposed bearings or a combination of more than two must be used. Since the rigidity of single-row angular contact ball bearings can be increased by preloading, they are often used in the main spindles of machine tools, for which high running accuracy is required. (Refer to Chapter 10, Preload, Page A96). Usually, the cages for angular contact ball bearings with a contact angle of 30° (Symbol A ) or 40°(Symbol B ) are in accordance with Table 1,but depending on the application, machined synthetic resin cages or molded polyamide resin cages are also used. The basic load ratings given in the bearing tables are based on the cage classification listed in Table 1. Though the figures in the bearing tables (Pages B50 to B61; bearing bore diameters of 10 to 120) show bearings with single-shoulder-type inner rings, both-shoulder-type bearings are also available. Please consult NSK for more detailed information. Table 1 Standard Cages for Angular Contact Ball Bearings Series

In addition, for bearings with the same serial number, if the type of cages are different, the number of balls may also be different. In such a case, the load rating will differ from the one listed in the bearing tables. Angular Contact Ball Bearings with contact angles of 15° (Symbol C) and 25° (Symbol A5) are primarily for high precision or high speed applications, and machined brass or synthetic resin cages or molded polyamide cages are used. The maximum operating temperature of molded polyamide cages is 120 °C. B 46

SELF-ALIGNING BALL BEARINGS SELF-ALIGNING BALL BEARINGS
Bore Diameter 5 – 110 mm ················ B74
DESIGN, TYPES, AND FEATURES The outer ring has a spherical raceway and its center of curvature coincides with that of the bearing; therefore, the axis of the inner ring, balls and cage can deflect to some extent around the bearing center. This type is recommended when the alignment of the shaft and housing is difficult and when the shaft may bend. Since the contact angle is small, the axial load capacity is low. Pressed steel cages are usually used.
PROTRUSION AMOUNT OF BALLS Among self-aligning ball bearings, there are some in which the balls protrude from the side face as shown below. This protrusion amount b1 is listed in the following table. b1 (mm)

INTERNAL CLEARANCE ········································ Table 9.12 (Page A90) PERMISSIBLE MISALIGNMENT The permissible misalignment of self-aligning ball bearings is approximately 0.07 to 0.12 radian (4° to 7°) under normal loads. However, depending on the surrounding structure, such an angle may not be possible. Use care in the structural design. B 72

SINGLE-ROW CYLINDRICAL ROLLER BEARINGS
Four-Row Cylindrical Roller Bearings are described on Pages B330 to B339.
DESIGN, TYPES, AND FEATURES Depending on the existence of ribs on their rings, Cylindrical Roller Bearings are classified into the following types.
NU
NJ
NNU
NUP
N
NF
NH
NN
Types NU, N, NNU, and NN are suitable as free-end bearings. Types NJ and NF can sustain limited axial loads in one direction. Types NH and NUP can be used as fixed-end bearings. NH-type cylindrical roller bearings consist of the NJ-type cylindrical roller bearings and HJ-type L-shaped thrust collars (See Page B102 to B105). The inner ring loose rib of a NUP-type cylindrical roller bearing should be mounted so that the marked side is on the outside.

Besides metric design tapered roller bearings, there are also inch design bearings. For the cone assemblies and cups of inch design bearings, except four-row tapered roller bearings, the bearing numbers are approximately formulated as follows: Example:

Among inch design tapered roller bearings, there are those to which the following precision classes apply. For more details, please consult with NSK. (1) J line bearings(in the bearing tables, bearings preceeded by )
For tapered roller bearings, besides single-row bearings, there are also various combinations of bearings. The cages of tapered roller bearings are usually pressed steel.

DESIGN, TYPES, AND FEATURES THRUST BALL BEARINGS
Thrust ball bearings are classified into those with flat seats or aligning seats depending on the shape of the outer ring seat (housing washer). They can sustain axial loads but no radial loads. The series of thrust ball bearings available are shown in Table 1. For Single-Direction Thrust Ball Bearings, pressed steel cages and machined brass cages are usually used as shown in Table 2. The cages in DoubleDirection Thrust Ball Bearings are the same as those in Single-Direction Thrust Ball Bearings of the same diameter series. The basic load ratings listed in the bearing tables are based on the standard cage type shown in Table 2. If the type of cage is different for bearings with the same number, the number of balls may vary, in such a case, the load rating will differ from the one listed in the bearing tables.

CYLINDRICAL ROLLER THRUST BEARINGS
These are thrust bearings containing cylindrical rollers. They can sustain only axial loads, but they are suitable for heavy loads and have high axial rigidity. The cages are machined brass. SPHERICAL THRUST ROLLER BEARINGS
These are thrust bearings containing convex rollers. They have a selfaligning capability and are free of any influence of mounting error or shaft deflection. Besides the original type, the E type with pressed cages for high load capacity is also available. Their bearing numbers are suffixed by E. For horizontal shaft or high speed application, machined brass cages are recommended. For details, contact NSK. Since there are several places where lubrication is difficult, such as the area between the roller heads and inner ring rib, the sliding surfaces between cage and guide sleeve, etc., oil lubrication should be used even at low speed. The cages in the original type are machined brass.
TOLERANCES AND RUNNING ACCURACY
DIMENSIONS RELATED TO MOUNTING The dimensions related to mounting of spherical thrust roller bearings are listed in the Bearing Table. If the bearing load is heavy, it is necessary to design the shaft shoulder with ample strength in order to provide sufficient support for the shaft washer.
PERMISSIBLE MISALIGNMENT The permissible misalignment of Spherical Thrust Roller Bearings varies depending on the size, but it is approximately 0.018 to 0.036 radian (1° to 2°) with average loads.
MINIMUM AXIAL LOAD It is necessary to apply some axial load to thrust bearings to prevent slippage between the rolling elements and raceways. For more details, please refer to Page A99.

DESIGN, TYPE, AND FEATURES DOUBLE-DIRECTION ANGULAR CONTACT THRUST BALL BEARINGS
Double-Direction Angular Contact Thrust Ball Bearings are specially designed high precision bearings for the main spindles of machine tools. Compared with the Thrust Ball Bearings in the 511 Series, this type contains more balls of smaller diameter and has a contact angle of 60°. Consequently, the influence of centrifugal force is less and they can withstand higher speed and have higher rigidity. Bearings in Series 20 and 29 have the same inner and outer diameters as the double-row cylindrical roller bearings in Series NN30 and NN49 respectively, and they are both used for high axial loads. Their cages are machined brass. There are the BTR, BAR Series of highly rigid angular contact ball bearings suitable for high speed that can be easily replaced by these double- direction angular contact ball bearings. For more details, please contact NSK. ANGULAR CONTACT THRUST BALL BEARINGS FOR BALL SCREWS
Bearings of this type were specially designed to support NSK Precision Ball Screws. They are usually used in combinations of more than two bearings and with a preload. Their contact angle is 60°. For more details, please refer to Catalog CAT. No. E1254 SUPER PRECISION BEARINGS. Their cages are molded polyamide.

In this catalog, only the types marked by are shown.
SN SN SN SN SN SN
5 6 30 31 2 3
SN 2C SN 3C
These are the most common type. Models SN30 and SN31 are for medium loads. For types SN2C and SN3C, the bore diameters on the two sides are different.
SN 5B SN 6B SN 30B SN 31B SN 2B SN 3B SN 2BC SN 3BC
These have the same dimensions as those of types SN5 and SN6. To increase the bearing box strength, no material is removed from the top or bottom of t he base, so mounting holes can be drilled anywhere.
Dustproof plummer blocks have a combination of oil seals, labyrinth seals, and oil groove seals, therefore, they are suitable for environments with much dust and other foreign matter.
SD SD SD SD SD SD SD SD
These are large and made for heavy loads. The standard ones have double seals and four mounting bolt holes. For types SD2C and SD3C, the bore diameters on the two sides are different.
SG 5
SD31TS SD32TS
V·C
These are provided with labyrinth seals, so they are suitable for high speed applications. B 300
30S 31S 5 6 2 3 2C 3C
Single-piece plummer blocks (integrated type roller bearing unit)have higher rigidity and precision than split type plummer blocks.

DESIGN, TYPES, AND FEATURES Four-row tapered roller bearings and four-row cylindrical roller bearings used for rolling-mill roll necks are easy to service and check, and are designed to have the highest load rating possible for the limited space around roll necks. Also, they are designed for high speed to satisfy the demand for fast rolling. In addition to the open type (KV) four-row tapered roller bearings listed in this catalog, sealed-clean type four-row tapered roller bearings are also available. Please refer to “Large-Size Rolling Bearings” catalog (CAT. No. E125) or “Extra-Capacity Sealed-Clean TM Roll Neck Bearings” catalog (CAT. No. E1225) for more detailed information.

Railway Rolling Stock Bearings Railway rolling stock bearings are important components of rolling stocks that require high reliability. The main bearings consist of axle bearings that are mounted at both ends of axle and support the entire weight of the rolling stock. Additionally, there are railway traction motor bearings that are used for the motor that drives the axle; and gear unit bearings that transfer the power from the motor to the axle. NSK has designed and manufactured specific bearings for these very applications.
Types and Features Axle Bearings
•
Axle bearings consist of the following types of bearings to meet operator demands for high-speed capability of rolling stock, weight reductions, and minimal maintenance and inspection requirements: ➣ Cylindrical roller bearings with a thrust collar (oil bath lubrication, grease lubrication) ➣ Tapered roller bearings (oil bath lubrication) ➣ RCC Bearings (sealed-clean rotating end cap cylindrical roller bearings) (grease lubrication) ➣ RCT bearings (sealed-clean rotating end cap tapered roller bearings) (grease lubrication) • NSK has been approved by AAR (Association of American Railroads). Traction Motor Bearings
•
Bearings for inverter controlled AC motors are speciality designed to meet high-speed specifications and requirements for ensuring dimensional stability. NSK recommends longlife grease for these bearings. • NSK offers the following bearings as a measure against electric erosion, which occurs when electric current is allowed to flow through the motor bearings: ➣ Ceramic-insulated bearings (ceramic-coated bearings) and PPS-insulated bearings • High capacity bearings also available for locomotive-type large traction motors Axle Bearings
Gear Unit Bearings
• These bearings are designed to meet high-speed specifications and offer excellent seizure resistance. • A reinforced cage has been adopted for these bearings.
