Thrust ball bearing is made by axial ring, washer, ball and retainer.

According to the force situation, it is divided into unilateralism thrust ball bearings and double direction thrust ball bearings.

Unilateralism thrust ball bearing can bear axial load in one direction, double direction thrust ball bearings can withstand bidirectional axial loads, of which the collar and the shaft cooperate. 

Applications: Heavy machine hook, vertical pump, vertical centrifuge, jack, low speed reducer, etc.
