The inner ring and the outer ring are set up coaxially. The rolling body is connected between the inner ring and the outer ring. At least 5 rolling bodies are set up annularly. The holder is used to connect the rolling bodies. At least 3 lubrication holes are set up annularly on the front end surface of the outer ring. The lubrication hole is of L shape. The end of the lubrication hole away from the outer ring faces the inner surface of the inner ring. A sealing plug is set up in the lubrication hole. A circular groove is set up on the front end surface of the outer ring. The circular groove and the outer ring are set up coaxially. A cover is equipped in the circular groove. This device is convenient for lubrication and can effectively avoid a waste of lubricating liquid and increase utilization ratio of lubricating liquid.</p> |
