ABSTRACT:
An improved tractor roller or idler assembly for a track-type tractor. A stationary shaft is secured to the major or minor bogie. The shaft has an internal cavity which retains a supply of lubricating oil. Radially extending passageways are projected through the stationary shaft to its exterior surface. Sleeve bearings rotate on the shaft and enhance rotation of the roller or idler. Lubricating oil is permitted to flow through the radially projecting passageways to lubricate the sleeve bearings. A filter, disposed within the radially extending passageways and extending into the internal cavity, assures that harmful contaminants in the lubricating oil do not reach or interfere with the sleeve bearings.
