Thrust ball bearings are made up of shaft washer, housing washer, steel balls and cage. The bearing with housing washer which has spherical mounting surface is self-aligning, which can reduce the effects of mounting error. Thrust ball bearings are mainly used under axial loading, it can transfer large axial loads, but can not carry radial load. Thrust Ball Bearings supplied by ZWLXJ: 1. Single Direction Thrust Ball Bearings: The type 51000, they can only carry axial load in single direction, and restrict the shaft and housing in the direction of axial movement. Can not carry radial load 2. Double Direction Thrust Ball Bearings The type 52000, center washer coordinate with axle. Double direction thrust ball bearings can carry a two-way axial load, can be restricted in the case of two axis and the direction of axial movement. Can not carry radial load. 3. Thrust Angular Contact Ball Bearings The type 560000, thrust angular contact ball bearings mainly carry axial load in one direction, can restrict the shaft and a housing in the direction of axial movement, at the same time can carry a certain degree of radial load. Angles of thrust angular contact ball bearings supplied by ZWLXJ includes 45° and 60° .
