Abstract
A track roller assembly supports and guides the link rails of the endless track of a track-type vehicle as the endless track travels along the ground. Contact between the link rails and the roller assembly is at the tread portion of the roller. A replaceable tread ring on the roller tread portion has a non-metallic outer tread portion which contacts the link rails. The tread ring is held in place by a replaceable flange plate. A separate seal plate holds the various seals in place when the flange plate is removed for replacement of the tread ring or the flange plate. Conventional track roller assemblies have non-replaceable flange plates and metal tread portions which produce considerable wear on the mating link rails. The subject roller assembly prolongs the useful life of the link rails and provides an easily replaceable flange plate and tread ring.
