1. The inner ring usually fits tightly with the shaft and rotates together with the shaft.

2. The outer ring is usually matched with the bearing seat hole or mechanical part shell to play a supporting role. However, in some applications, the outer ring rotates, the inner ring is fixed, or both the inner ring and the outer ring rotate.

3. The rolling elements are evenly arranged between the inner ring and the outer ring by means of the cage. Its shape, size and quantity directly affect the bearing capacity and performance of the bearing.

4. The cage evenly separates the rolling elements, guides the rolling elements to move on the correct track, and improves the internal load distribution and lubrication performance of the bearing.
