[0002] Bearings are an important component in contemporary mechanical equipment. Their main function is to support mechanical rotating bodies, reduce the friction coefficient during their movement, and ensure their rotation accuracy. Most existing bearings are open structures. When in use, the rollers are exposed. Dust can easily enter the bearings and affect the rollers, which can easily affect the use of the bearings. In general, in order to prevent dust from entering the bearings, dust plates are usually added at both ends of the bearings. However, the existing dust plates are directly inserted into the bearings, which is not convenient for installation and removal. In addition, during the use of the bearings, the lubricating oil flows to the outside of the dust plates to form waste oil, which is not convenient for cleaning.
