Thrust ball bearing
- Sep 18, 2018 -

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


Thrust ball bearing composition:

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

The so-called shaft ring that cooperates with the shaft, and the seat ring that cooperates with the outer casing.


One-way thrust ball bearings and two-way thrust ball bearings are classified according to the force. One-way thrust ball bearings can withstand one-way axial loads.

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

Thrust ball bearings cannot withstand radial loads and have lower limit speeds.


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

2. In order to allow installation errors, either spherical or spherical, you can choose either a spherical or spherical seat type or a spherical seat type.

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

4. High grease technology - NSK's lubricant technology extends grease life and improves bearing performance

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

6. Use the ferrule in the option to allow for installation errors
