Thrust Ball Bearing

The thrust ball bearing is designed to withstand the thrust load at high speed and consists of a gasket ring with a ball rolling raceway groove. Because the ring is cushioned, thrust ball bearings are divided into two types: flat-bottom cushion and center-adjusted spherical cushion. In addition, the bearing can withstand axial load, but not radial load.

The material of the cage is divided into stainless steel and brass, the planar thrust ball bearing is a separable bearing, contact angle 90, can be installed separately and can only withstand axial load. The limit of thrust ball bearing: single direction thrust ball bearing can only withstand one direction axial load. Double direction thrust ball bearing can withstand bidirectional axial load. The thrust ball bearing with spherical seat ring has the function of adjusting center and can eliminate the influence of installation error.
