ABSTRACT:
A seal assembly for antifriction bearings in which a cone and a cup have raceways for roller bearings, a seal case carried by the cone and by the cup for supporting a seal element on each of the seal cases to provide a space therebetween for retention of a body of lubricant in position to create a barrier for blocking the ingress of contaminants from the exterior. One of the seals is positioned to be exposed to the outside to have a lip operative on one of the seal cases to preclude the ingress of contaminants, and the other one of the seals is exposed to the bearing interior to allow lubricant to pass into the cavity between the seals and also to assure the presence of lubricant to the interior of the bearing assembly.
