[0002] Bearings are a commonly used mechanical component that can be used in support, rotation systems and transmission systems. They support components, connect rotating parts and reduce friction, and play an important role in many fields.

[0003] The bearing ring is a component of the bearing. The bearing ring usually fits tightly with the shaft and rotates with the shaft. In order to reduce the friction between the bearing ring and the shaft, the bearing ring needs to be polished to reduce its surface roughness to reduce the friction between the outer side of the bearing ring and the rolling element. By applying a certain pressure and movement on the surface of the bearing ring, the surface becomes smooth, which can improve its surface quality and performance and extend its service life. When using the existing polishing machine, the inner ring of the bearing needs to be moved to the polishing machine, and manpower is also required to move the inner ring of the bearing away from the polishing machine, which increases the consumption of manpower and the labor intensity of the staff. The work efficiency is low and it is far from meeting the needs of mass production. Utility Model Content
