A seal assembly for sealing between first and second tubular members includes an annular seal body disposeable within an annular gland between the tubular members and formed of a generally compressible polymeric material. The seal body has a first axial sealing surface disposed against a first tubular member end surface, a second axial sealing member disposeable against a second tubular member end surface and a recess(es) defined partially by an angled activation surface. An annular backing ring formed of a substantially rigid material is disposed the body recess to couple the backing ring with the seal body. The backing ring has an outer axial end disposeable against the first member end surface to prevent radially outward displacement of the portions of the seal at the first member end surface and is biased axially toward the first member end surface when compression of the seal body displaces the activation surface axially.

Axial face seal assembly with outwardly-biased backing rings

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.
