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.

Abstract: 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. The load ring includes a main body and a neck having a neck perimeter with a first sealing blade disposed along the neck perimeter and comprising an outwardly-extending projection. The first sealing blade is adapted to sealingly engage one of the seal ring and the first member.
