Abstract
A sealed antifriction bearing with an inner and outer ring and rolling elements between them includes sealing rings at both axial ends of the annular space between the rings. A sealing ring is fixed to the outer ring and rotates with it. At the inner ring, the sealing ring has a resilient sealing lip with a sealing edge adjacent the inner ring. Projections from the sealing lip project toward the inner ring and are wedge shaped and oriented such that relative rotation of the outer and inner rings causes the projections to convey lubricating oil axially into the annular space between the bearing rings. The sealing lip has a less inclined surface axially inward of the sealing edge and a more sharply inclined surface outward of the sealing edge. The projections are on the sealing lip surface axially inward of the sealing edge.
