A deep groove ball bearing seal assembly

The utility model relates to a deep groove ball bearing sealing assembly which is characterized in that a sealing lip of the sealing assembly is L-shaped, one end of the sealing lip is clamped on a steel framework, and an oil groove is formed in the contact surface of the other end of the sealing lip and an inner ring; the sealing lip and the steel framework form a sealing ring; the outer diameterof the sealing ring is in interference contact with the outer ring, and the inner diameter of the sealing ring is in interference contact with the inner ring; and the retainer and the steel balls arearranged between the outer ring and the inner ring. By the adoption of the sealing ring, outside particles and dirt are not prone to making direct contact with the sealing lip piece, and the servicelife of the sealing ring is prolonged; the sealing lip pieces are radially pressed on the inner surface of the inner ring for sealing through the steel framework, sealing is reliable, the formed oil grooves can exhaust expanded
