Preload of Spherical Thrust Roller Bearings

When spherical thrust roller bearings are used, damage such as scoring may occur due to sliding between the rollers and outer ring raceway. The minimum axial load (F amin ) necessary to prevent such sliding is obtained from the following equation:

F amin =Minimum
