Thrust bearings generally consist of two thrust washers or more thrust washers and a number of rolling elements. Generally, thrust washers are divided into shaft and seat. The most common type of rolling element is iron or copper. The cages are combined into one. Thrust bearings are special bearings used to specifically support axial forces, and are bearings that are parallel to the direction of the shaft. Thrust bearings are also known as thrust bearings.

As the name implies, the thrust bearing is a dynamic pressure bearing. To make the bearing work normally, the following conditions should be met:

1. The lubricating oil has a viscosity;

2. There is a certain relative speed between the moving and the static body;

3. The two surfaces of the relative motion are inclined to form an oil wedge;

4. The external load is within the specified range;

5, enough oil.
