An endless track assembly comprises a plurality of pivotally interconnected links with each pair of adjacent links having an annular seal assembly mounted therebetween. The seal assembly comprises an elastomeric crescent-shaped seal having a lip disposed in sealing contact with a sealing surface defined in the track assembly. An annular elastomeric load ring is disposed within the seal to urge the lip into such sealing contact. A metallic reinforcing ring, disposed between the lip and the load ring, is preferably bonded only to the lip.
