ABSTRACT:
A track roller for a continuous track on a crawler tractor or the like comprises two sections welded together to define an interior lubrication cavity which communicates by means of lubrication passages to spaces containing bearings and to an exterior lubrication port. The track roller has a central cavity with a foam material holding a lubricant in its open cells. Axles extend from the track roller and through which a passage extends to communicate with the cavity. The axles are supported by bearings in the caps that are fixedly and non-rotatably mounted on the frame that supports the track roller. The passage in each axle permits lubricant to pass from the cavity to the bearings.
