Abstract
Track roller for track-laying vehicles such as excavators having a shaft, a roller body rotatably supported thereon, two caps for limiting relative axial movement of shaft and roller body, and end pieces for attaching the track roller to the frame. The shaft has at its center a relatively large diameter, laterally thereof, spaced axially from each other, two relatively wide cylindrical bearing surfaces of larger diameter and, on its sides, ends of reduced diameter with elastic packings at suitable places between the end pieces and the caps and between the caps and the roller body, and an antifriction metal washer arranged between shaft and caps for the feeding of oil to those packings requiring lubrication which is effected from the oil space arranged between the bearing surfaces of the shaft and serves as an oil reservoir.
