[0002] Bearings are 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. Bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage. In order to ensure the service life of the bearing, it is usually necessary to install a sealing device in the bearing to play a sealing and dustproof role, so that the bearing is fully lubricated during operation and prevent external impurities from entering the bearing. When the bearing space is limited, it cannot meet the installation requirements of the sealing structure, and it is difficult to achieve a good bearing sealing effect, which affects the normal operation of the bearing. The assembly of the bearing is generally a snap-on connection. Although it is easy to load and unload, it is easy to wear and scrap during the assembly process. At the same time, its assembly strength is also limited, which does not meet the use requirements. Summary of the invention
