ABSTRACT:
A track roller assembly for guiding an endless track includes a central supporting shaft, a roller shell having a through bore, a pair of bushings surrounding the shaft and positioned within the roller through bore, and a pair of split rings which secure the roller shell in a fixed position with respect to the bushings and the shaft. A seal assembly at each end of the through bore seals in lubricating fluid and seals out dirt and other harmful matter. The split rings hold the shaft, bushings, and roller shell together and eliminate threaded fasteners which reduce the useful wear life of the roller shells. Resilient load rings in the seal assemblies provide proper loading of the seal assemblies and prevent dirt from eroding the load rings.
