Abstract
A replaceable composite tread ring for a track roller assembly of a track-type vehicle includes a non-metallic outer tread portion and a metallic inner base portion. The metallic base portion is C-shaped and encloses portions of the non-metallic tread. Conventional track roller assemblies have non-replaceable metal tread portions which produce considerable wear on the mating link rails. The subject composite tread ring prolongs the useful life of the link rails by reducing the wear of the rails, since the rails contact the non-metallic portion of the tread ring.
