ABSTRACT:
A cartridge bearing assembly for a track chain of a track type work machine is provided. The cartridge bearing assembly includes axial/radial load bearing insert members positioned about a pin, and a rotatable bushing positioned therebetween. Crowned sleeve bearings are disposed between the insert members and the pin, as well as between the pin and the rotatable bushing. Collars are disposed at opposite ends of the pin and fixedly coupled thereto, trapping the other components of the cartridge assembly therebetween. A method of operating a track type work machine is further provided, including reducing wear between coupled track links by reacting axial loads via insert members positioned about a track pin.
