A seal assembly for the pivot of a track of a tracklaying vehicle comprises an annular U-section nonmetallic and elastomeric seal and a metallic load ring received in the groove formed between the sides of the seal which bear in turn on a pair of axially confronting flanks of a pair of relatively pivotal members each belonging to a respective track segment. The metallic load ring has a pair of sides each bearing axially against a respective surface of a respective side of the seal and is received between the sides of the seal. This load ring may be of U-section, or may be constituted by a pair of oppositely dished metal washers.
