Thrust ball bearings

The thrust ball bearing is designed to bear thrust load when running at high speed, and is composed of a washer like ring with ball rolling raceway groove. Because the ring is cushion shaped, the thrust ball bearing is divided into two types: flat bottom cushion type and self-aligning spherical cushion type. In addition, the bearing can bear axial load, but cannot bear radial load.

It is divided into one-way thrust ball bearing and two-way thrust ball bearing according to the stress conditions. One way thrust ball bearing can bear one-way axial load. Two way thrust ball bearing, which can bear two-way axial load, in which the shaft ring is matched with the shaft. The mounting surface of the race is spherical bearing, which has centering performance and can reduce the influence of installation error. The thrust ball bearing cannot bear radial load, and the limit speed is low.

Applications of thrust ball bearing: it is only applicable to mechanical parts bearing axial load on one side and low speed, such as crane hook, vertical water pump, vertical centrifuge, Jack, low-speed reducer, etc. The shaft ring, seat ring and rolling element of the bearing are separated and can be assembled and disassembled separately
