Abstract
A seal assembly is for a spherical plain bearing with an inner ring mounted on a shaft and an outer ring disposed about the inner ring and having a concave inner surface slidably displaceable against the inner ring convex outer surface. The seal assembly includes an annular inner member disposed about the shaft axially adjacent to the bearing inner ring and having opposing first and second axial ends and an outer engagement surface extending axially between the first and second ends. A generally annular outer member has a base portion coupled with the bearing outer ring and a lip portion extending radially inwardly from the base portion and having an outer end sealingly engageable with the outer engagement surface of the seal inner member. The lip portion slidably displaces generally axially along the inner member engagement surface when the outer ring displaces axially relative to the inner ring.
