[0002] With the development of industrial technology, bearings are more and more widely used in various mechanical equipment. Ball bearings are composed of multiple parts that cooperate with each other. In order to facilitate the free movement of each part, there is a certain distance between each part. Therefore, a high-sealing bearing structure is required to prevent dust from entering the bearing. However, the existing device still has certain defects when used, such as:

[0003] The patent number "CN202110758310.X" discloses a bearing with good rotation effect and high sealing. When in use, the device is divided into two parts by a base and a top cover, which is convenient for fixing and installing the bearing, and for adjusting the tightness of the base and the top cover. While reducing friction, it is convenient to adjust according to the size of the bearing. However, during the use of the device, a large amount of heat will be generated during the rotation of the bearing, which will cause the bearing to deform due to excessive temperature, thereby affecting the normal operation and service life of the bearing.
