Thrust Ball Bearing 51108 With High Precision

thrust ball bearing

Thrust ball bearings are divided into single and double direction types. The former is able to accommodate 

axial load in one direction, while the latter is able to accommodate it in both directions. 

Neither is suitable for applications that involve radial load or high-speed rotation. Bearings whose housing washer back face is spherical (with a spherical back face 

or aligning seat washer) 

are designed with a self-aligning capability and can accommodate the effects of inaccurate mounting. 

With flat back faces: 51100  51200  51300  51400 

With spherical back face: 53200  53300  53400 

With aligning seat washer: 53200U  53300U  53400U

Thrust ball bearings can support high axial forces but must not be subjectedto radial loads, single and double direction designs available. 

Thrust ball bearings 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.
Applications:
Live centers in lathes, lead screws, automotive clutches, kingpin supports, speed reducers
