-15- Abstract of the Disclosure Track Roller Assembly A track roller assembly supports and guides a portion of the endless track of a track type vehicle as that portion of the track travels between a drive wheel and an idler wheel of the vehicle. The rim portions of the roller assembly include a plurality of alternating resilient non-metallic rings and metallic rings. The non-metallic rings are compressed between the metallic rings to increase the diameter of the outer walls of the rings. The link rails contact the non-metallic rings only. Conventional track supporting rollers have metallic treads which generate noise and impact against the metal link rails. The rollers often fail to rotate due to insufficient friction with the link rails. The subject roller assembly, with resilient rings in contact with the link rails, generates low levels of noise and vibration and produces sufficient friction to rotate the rollers.
