ABSTRACT:
A track roller assembly for a track-type machine such as an excavator or a tractor includes an outer surface with no fluid ports and an inner surface free from any fluids. The track roller includes a shaft resting on self-lubricated bushings, which include a substrate that has lubricating properties, such as a substrate that carries a solid lubricant. The track roller assembly also includes a collar on either side of the shaft, with a retention pin passing through the shaft and connecting the two collars.
