Thrust ball bearing

         According to the force situation, it is divided into one-way thrust ball bearing and two-way thrust ball bearing. One way thrust ball bearing can bear one-way axial load. The two-way thrust ball bearing can bear two-way axial load, and the shaft ring is matched with the shaft. The bearing with spherical mounting surface of seat ring has self-aligning performance, which can reduce the influence of installation error. The thrust ball bearing can not bear the radial load and the limit speed is low.
