○ Thrust ball bearings consist of ball. retainer. both shaft and housing washers which contain grooves for the balls. ○ This Bearing consists of 3 kinds of grooved washer bearing rings. 2 kinds of cage and ball assembly. ○ Aligning seat washers with an aligning surface radius are also available for ease of design and mounting against a flat housing shoulder.
1. The design of Thrust Ball Bearing may not be subjected to any radial load. Thrust Ball Bearings are not suitable for high-speed rotation since lubricant is expelled by centrifugal force. 2. When used on a horizontal shaft. a minimum axial load must be applied. 3. Care must be taken in handling to prevent damage to the separable rings and ball assembly.
○ Machines in general
1. Ball Thrust Bearings should use close to the radial bearing. in order to prevent the effect of shafts deflection. 2. When using big size ball bearings on a horizontal shaft. preload should be implemented to prevent the clearance between housing washer and balls. 3. Under the inevitable circumstances of shaft deflection and misalignment. aligning seat washer should be applied.
