Shaft Axis
Type ini utamanya terjadi pada part bentuk disk yg tipis, misalnya : flywheel, turbine disk Can be corrected by single plane Priciple Inertia Axis = Sumbu Inersia C.G = Center of Gravity
COUPLE UNBALANCE Terjadi bila : Sumbu inersia berpotongan dgn sumbu shaft pada posisi C.G C.G
Shaft Axis Unbalance
