Description:

Thrust ball bearings are able to bear radial load and axial load. As single row angular contact  ball bearings can only bear axial load in single direction, matched bearing mounting is often adopted. As matched pairs  bearings preload for them is more convenient retainers are made of brass, synthetic reins or other materials depending on different bearings features and application conditions.

Specification:

Applications:                        

Thrust ball bearing  are widely used in the common industry, automobile industry, agriculture, industry and household appliances industry.
