Thrust ball bearing

Thrust ball bearings are designed to withstand thrust loads at high speeds and consist of washer-like rings with raceway grooves for ball rolling. Because the ferrule is cushion-shaped, thrust ball bearings are divided into two types: flat base cushion type and self-aligning spherical cushion type. In addition, this kind of bearing can bear axial load, but cannot bear radial load.

According to the stress situation, it can be divided into one-way thrust ball bearing and two-way thrust ball bearing. One-way thrust ball bearings can bear one-way axial load. Two-way thrust ball bearings can withstand two-way axial loads, in which the shaft ring is matched with the shaft. The mounting surface of the seat ring is a spherical bearing, which has self-aligning performance and can reduce the influence of installation errors. Thrust ball bearings cannot bear radial loads, and the limit speed is low.

Applications of thrust ball bearings: only suitable for parts that bear axial load on one side and low speed, such as crane hooks, vertical water pumps, vertical centrifuges, jacks, low-speed reducers, etc. . The shaft ring, seat ring and rolling elements of the bearing are separated and can be assembled and disassembled separately.
