Double row thrust ball bearing

The thrust ball bearing adopts a design that can withstand thrust loads during high-speed operation, and is composed of a washer like ring with a ball rolling raceway groove. Due to the cushion shaped collar, thrust ball bearings are divided into two types: flat bottom cushion type and self-aligning spherical cushion type. In addition, this type of bearing can withstand axial loads, but cannot withstand radial loads.

According to the force situation, it is divided into unidirectional thrust ball bearings and bidirectional thrust ball bearings. Unidirectional thrust ball bearings can withstand unidirectional axial loads, while bidirectional thrust ball bearings can withstand bidirectional axial loads, with the shaft ring and shaft fitting. The bearing with a spherical installation surface of the seat ring has centering performance, which can reduce the impact of installation errors. The thrust ball bearing cannot withstand radial loads and has a lower limit speed.

Thrust ball bearings are only suitable for parts that bear one axial load and have low rotational speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. The shaft ring, seat ring, and rolling element of the bearing are separate and can be installed and removed separately.
