Abstract
A seal assembly can be incorporated into a track joint assembly of an undercarriage of a track-type machine. The track joint can have a first member pivotable about a rotational axis relative to a second member thereof. The first member includes a seal member engagement surface defining, at least in part, an axially-extending seal cavity about the rotational axis and within which the seal assembly is disposed. The seal assembly can include a thrust ring and a seal member mounted to the thrust ring. The seal member includes a first member engagement surface, a second member engagement surface, a frusto-conical inner relief surface, a thrust ring engagement surface, and an outer relief surface.
