A radial seal assembly for sealing a lubricant-containing bearing cavity in an anti-friction bearing includes a rigid annular ring mounted in a cylindrical bore of the outer bearing case and a resilient sealing body bonded onto the ring and engaging an outwardly directed cylindrical sealing surface supported for rotation relative to and coaxially with the cylindrical bore in the bearing case. The seal body includes an outer dust seal lip engaging the sealing surface and a primary lubricant seal lip forming a dynamic seal with the sealing surface. The primary seal lip has a generally conical surface on the side thereof directed toward the bearing cavity, and a plurality of oil deflectors are integrally formed on and project from the conical surface within the annular space between the conical surface and the sealing surface, with the respective oil deflectors having leading and trailing surfaces inclined with respect to the direction of relative rotation.
