Thrust Ball Bearing for Crane Hook (51730-51791)

Brief Introductions
Thrust ball bearing consist of two precision chrome steel washers (ring) and a ball complement spaced by bronze retainer. They can be supplied with or without radius ball grooves in the rings. Thrust bearings are used under purely axial loads. 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. Types of bearings

Axial loads in one direction can be sustained.
2) Double-Direction Thrust Ball Bearings
