Q: What are thrust ball bearings and what are their characteristics?

A: 

Thrust ball bearing composition:

The thrust ball bearing is composed of three parts: seat ring, shaft ring, and steel ball cage assembly.

The shaft ring matched with the shaft is called the seat ring, and the housing ring matched with the housing.

Thrust ball bearing types:

　　 According to the force, it is divided into one-way thrust ball bearings and two-way thrust ball bearings.

        One-way thrust ball bearings can bear a one-way axial load.

　　 Two-way thrust ball bearings can bear a two-way axial load. Two-way thrust ball bearings, in which the ring matches the shaft. The mounting surface of the seat ring is a spherical bearing with self-aligning performance, which can reduce the influence of installation errors.

　　 Thrust ball bearings cannot bear radial load, and the limit speed is low.

Features

　　1. Available in one-way and two-way types

　　2. In order to tolerate installation errors, whether it is one-way or two-way, you can choose spherical self-aligning spherical seat cushion type or spherical seat ring type.

　　3. High-quality steel ― Using ultra-clean steel that can extend bearing life by up to 80%

　　4. Advanced grease technology-NSK’s lubricant technology can extend the life of grease and improve bearing performance

　　5. High-grade steel ball ― quiet and smooth at high speed

　　 6. Using the ferrule in the option, installation errors can be tolerated.
