ABSTRACT:
An endless track chain with a rotatable bushing is disclosed that utilizes sleeve bearings for rotatably mounting the inboard end collars of the links about the pin. The joint of the track chain is sealed and lubricated. Sealing rings for the joint incorporates the use of a second set of seals for sealing between the rotatable bushing and the inboard end collars of the link. A unique design for the links enables the chain to accommodate the second set of seals without any loss of structural integrity in the chain or any disadvantageous increase in rail gauge width ('G") of the chain. The track chain also utilizes a punch for mechanically interlocking the outboard end collars of the links to the end portions of the pin to eliminate joint end play.
