Abstract
A hub rotates around the end of an axle housing on a tapered roller bearing which is packed with grease. The axle housing, which is part of a drive axle, conveys lubricating oil to the interior of the hub, but the oil does not encounter the grease, for a seal, which is fitted into the end of the bearing, separates the oil from the grease. The seal pumps the grease back to the interior of the bearing and the oil away from the interior of the bearing.
