Product Description

Product Description

 

Thrust ball bearings have a small contact surface with the bearing raceway which reduces friction. Low friction allows ball bearings to run at higher speeds but with a lower load capacity than roller bearings. These bearings support axial, or thrust, loads in a single direction.

The banded ball thrust bearings ease installation and provide extra protection to the internal bearing components against contaminants. They consist of a housing washer, a shaft washer, and a ball and cage assembly that are banded together as one unit.
 

The B20 thrust bearing is a single acting, flat seat design thrust ball bearing with a 1-11/16" bore and grooved races. What separates this bearing from some of the other B20 bearings on the market is its precision-made components, 52100 thru-hardened steel rings and balls, and high-quality, low-carbon steel band. This bearing is also supplied with light oil lubrication from the factory and features an oil hole in the band for relubricating. Thrust ball bearings are rotary bearings designed to support a predominately axial load. B20 bearings are composed of bearing balls that are supported in a ring and allow for use in applications with low thrust and little axial load.

Structure of thrust ball bearings

The structure of thrust ball bearings usually comprises a seat ring, a shaft ring, and a steel ball cage component. The shaft ring matched the shaft, and the seat ring matched the shell. The steel ball cage component keeps steel balls in the correct position in the bearing.

Classification of thrust ball bearings

According to the force, the thrust ball bearings can be divided into two types: single-direction thrust ball bearings and double-direction thrust ball bearing.

Single-direction thrust ball bearings can withstand unidirectional axial loads, while double-direction thrust ball bearings can withstand two-way axial loads.
