Thrust Ball Bearings

Thrust ball bearings can handle loads in the axial direction 
only. Bearing rings mounted on the shaft are called shaft 
washers, and those mounted in the housing are called housing 
washers. Both washers contain raceways for the balls.

Thrust ball bearings are available as both single and bi-directional 
types. The bi-directional thrust bearing incorporates a third 
washer and an additional set of balls. This center washer is 
located in the axial direction by a shaft shoulder and sleeve.

Care must be taken in handling to prevent damage to the separable 
rings and ball assemblies.

Typical applications: live centers in lathes, lead screws, automotive 
clutches, kingpin supports, speed reducers
