Deep groove ball bearing sealing assembly

The invention relates to a deep groove ball bearing sealing assembly. Sealing lip pieces of the sealing assembly are each in an L shape; one end of each sealing lip piece is clamped on a steel skeleton, and an oil groove is formed in the face, making contact with an inner ring, of the other end of each sealing lip piece; the sealing lip pieces and the steel skeleton constitute a sealing ring; theouter circle of the sealing ring is in interference contact with an outer ring, and the inner circle of the sealing ring is in interference contact with the inner ring; and a retainer and a steel ballare arranged between the outer ring and the inner ring. By adopting the deep groove ball bearing sealing assembly, external particles and dirt are not prone to make contact with the sealing lip pieces directly, and thus the service life of the sealing ring is prolonged; through the steel skeleton, the sealing lip pieces are radially attached to the inner surface of the inner ring for sealing, andsealing is reliable; the f
