[0002] Bearings are components that fix and reduce the load friction coefficient during mechanical transmission. In other words, when other parts move relative to each other on the shaft, they are used to reduce the friction coefficient during power transmission and keep the center position of the shaft fixed. Bearings are an important component in modern mechanical equipment. Their main function is to support the mechanical rotating body and reduce the mechanical load friction coefficient of the equipment during transmission.

[0003] When the existing rolling mill bearings are in use, the outer wall of the inner bearing ring inside it rubs against the inner wall of the bearing shell, resulting in energy and kinetic energy loss during the rotation of the inner bearing ring, which will affect the service life of the inner bearing ring. In addition, the bearings will generate a lot of heat inside when used for a long time. If the heat is not removed in time, the internal deformation of the bearings may be easily caused by high temperature. Utility Model Content
