Abstract
A sealing assembly is adapted to be disposed between a stationary part and a rotary shaft in the stationary part so as to provide a seal in the gap between the stationary part and the rotary shaft. The sealing assembly has a slinger capable of rotating as a unit with the rotary shaft, and a rubber seal having a lip which makes a sliding contact with the slinger. The portion of the slinger contacted by the lip of the rubber seal is provided with apertures which allow a lubricating oil to flow into the region of the sliding contact between the lip of the seal rubber and the portion of the slinger.
