ABSTRACT:
A seal for an axle bearing lubricated with oil, including a swivel ring fixed to the shaft and protruding radially outward which operates in conjunction with a sealing ring connected to the bearing housing and protruding radially inward. Between the sealing ring and the swivel ring a separation ring is located which protrudes radially inward and is connected to the bearing housing. A number of surfaces on the insides of the sealing and separation rings, together with corresponding surfaces on the outside of the swivel ring, enclose annular gaps, whereby several of these surfaces are conically at an angle from the inside to the outside with regard to the cardioid of the shaft.
