ABSTRACT:
An annular metallic support member has a cylindrical surface mountable within a bore of the spherical plain bearing outer ring or bearing housing such that a conical surface of the metallic support member overlies the spherical member. An annular elastomeric seal lip is mounted on the conical surface of the metallic support member, and an elastomeric seal body is mounted on the conical surface of the metallic support member, axially inward of the elastomeric seal lip, such that the elastomeric seal lip and elastomeric seal body contact the spherical member. The elastomeric seal body may have grooves for supplying lubricant to the elastomeric seal lip.
