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

1. There are two types of unidirectional and bidirectional. 2. In order to allow installation errors, whether it is unidirectional or bidirectional, you can choose spherical self-aligning spherical seat cushion type or spherical seat type. 3. High-quality steel—Using ultra-clean steel that can extend bearing life by up to 80% 4. High grease technology—NSK's lubricant technology can extend grease life and improve bearing performance 5. High-grade steel balls— Quiet and smooth when rotating at high speed 6. With the ferrule in the option, installation errors can be tolerated.

Thrust ball bearings are only suitable for parts that bear axial load on one side and have low 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 separated and can be assembled and disassembled separately.
