8306 Flat Axial Thrust Ball Bearing 51306 High Speed 30*60*21mm 51306

The thrust ball bearing adopts a design that can withstand thrust loads during high-speed operation, and is composed of a washer shaped ring with a rolling groove for the ball. Due to the cushion shaped ring, thrust ball bearings are divided into two types: flat bottomed cushion type and self-aligning spherical cushion type. In addition, this type of bearing can withstand axial loads,but cannot withstand radial loads. Divided into unidirectional thrust ball bearings and bidirectional thrust ball bearings according to the force situation. Unidirectional thrust ball bearings can withstand unidirectional axial loads. Bidirectional thrust ball bearings can withstand bidirectional axial loads, where the shaft ring is matched with the shaft. The installation surface of the seat ring is a spherical bearing with self-aligning performance, which can reduce the impact of installation errors.
