High-strength dustproof and waterproof thin-wall bearing

The high-strength dustproof and waterproof thin-wall bearing comprises an outer ring, working balls are evenly arranged on the inner side of the outer ring, an inner ring is jointly arranged on the inner sides of the working balls, protection plates are arranged on the two sides of the outer ring and the two sides of the inner ring, and clamping plates are arranged at the bottoms of the sides, close to the outer ring, of the protection plates. A metal ball extending to the outside of the clamping plate is embedded into the clamping plate; through mutual cooperation of the installation plate, the groove, the installation groove A and the protruding block, connection and sealing between the protection plate and the inner ring are achieved, external dust and water stains are blocked on the outer side through the groove and the protruding block, and therefore the possibility that dust enters is avoided, and through mutual cooperation of the clamping plate, the rolling groove, the metal ball and the installation g
