High quality 51201 thrust ball bearing for vertical pumps 12*28*11mm
The thrust ball bearing is designed to bear thrust load at high speed, which is composed of washer ring with ball rolling raceway groove. Because the ring is cushion shaped, the thrust ball bearing can be divided into two types: flat bottom cushion type and self-aligning spherical cushion type. In addition, the bearing can bear axial load, but not radial load.
