The structure of a deep groove ball bearing with a snap ring includes a bearing body and a stop ring. The bearing body comprises an inner ring, an outer ring, a steel ball, a cage, a sealing ring and a skeleton. The outer wall of the outer ring is concave inward to form a stop groove. The stop groove is equipped with a stop ring. The stop ring is an open elastic part. The ratio of the depth of the stop groove to the thickness of the outer ring is 0.2-0.3. The deep groove ball bearing with snap ring can prevent the axial displacement of the bearing, with strong lubrication ability and long service life.
