Ball Bearings Overview

Ball Bearing is an important component in contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy.

Ball Bearings Classification

1. According to different contact angles:Rolling bearings are mainly divided into radial bearings and thrust bearings

2. According to the structure of rolling elements and rings:Rolling bearings can be divided into deep groove ball bearings, self-aligning ball bearings, angular contact ball bearings, thrust ball bearings, and cylindrical roller bearings, needle roller bearings, spherical roller bearings, tapered roller bearings, thrust spherical roller bearings, thrust tapered roller bearings, etc.

3. According to the number of rows of rolling elements:Rolling bearings can be divided into single row, double row and multi-row (three rows and four rows)
