A seal assembly can be incorporated into a track pin joint assembly including a pin defining a longitudinal axis, a first member and a second member both coaxial with the pin about the longitudinal axis. The first member is pivotable about the longitudinal axis with respect to the second member and includes a load ring engagement surface defining, at least in part, an axially-extending seal cavity disposed in proximal relationship to the second member. A seal assembly including a seal ring and a load ring is disposed in the seal cavity and sealingly engages the first member and the second member. At least one of a load ring engagement surface of the first member and an axial segment of a first member engagement surface of the load ring includes a convex rounded portion extending over at least half the axial length thereof.
