The thrust ball bearing and Thrust angular contact ball bearing consist of cage with a row of balls, shaft ring and housing ring. They belong to separable bearing and then could be mounted and dismounted from shaft or housing holes easily. The thrust ball bearing could be divided into single direction thrust ball bearing (51000 series) and double direction thrust ball bearing (5200 series) according to structure. It could be divided into thrust ball bearing with flat back faces and thrust ball bearing with aligning seat washer according to the different undersurface. Thrust ball bearing with aligning seat washer has spherical performance and could reduce the effects raised from mounting error. Single direction thrust ball bearing could carry single directional axial load and axial displacement of single directional limiting axle. Double direction thrust ball bearing could carry two directional axial load and axial displacement of limiting axle. However, such kinds of bearing could not carry radial load.
It has 45° and 60°contact angle for thrust angular contact ball bearing. Such kinds of bearing are especially suitable for such application that need mainly bear axial load and certain radial load. It could eke out thrust ball bearing that could only carry axial load while not the radial load. Radial load of such bearing depends on the contact angular. Normally, the smaller the contact angular, the bigger the radial load carried.
The thrust ball bearing mainly use steel stamping cage. When the outer ring ≥2500mm, it use solid cage.
