Sealing mechanisms are mounted on the upper and lower sides of the outer ring and the inner ring, respectively, and on the adjacent ends. A plurality of steel balls are movably mounted between the outer ring and the inner ring, and a retention groove is provided within the outer ring. The utility model utilizes the protective groove and the protective ring to provide a seal between the outer ring and the inner ring, preventing external dust and impurities from entering and damaging the bearing body, thereby significantly extending the bearing body's service life.
