Power steering oil seals are used in the power steering system of automobiles, which are used to prevent dust, sediment and water from entering the steering system, keep the gears lubricated, and ensure the normal operation of the power steering system. The inner diameter of the back support ring design strengthens the pressure resistance of the oil seal. The lip oil return groove design sends the sealed oil body back to the oil side, so as not to leak oil, and can reduce friction and temperature rise.
