Abstract: A track link includes a link body having first and second sides, a rail surface, a shoe engaging surface, and first and second end portions. A link pin bore at the first end portion is configured to receive a link pin. A bushing bore at the second end portion is configured to receive a bushing. A link pin boss is located at the first end portion on the first side and surrounds the link pin bore. A bushing boss is located at the second end portion on the second side and surrounds the bushing bore.

Abstract: A roller assembly for a ground-engaging track system includes a roller forming a shaft bore, and a roller shaft within the shaft bore and having a circumferential ramp surface. A roller retention system for the roller assembly includes a roller retention collar with an outer peripheral surface, and an inner peripheral surface that may include a wedge surface structured to friction fit the retention collar, within a collar bore in the roller, upon the circumferential ramp surface to limit axial displacement of the roller upon the roller shaft. The roller assembly may include two roller retention collars supporting the roller against axial displacement without use of thrust washers or the like, and fixing the roller and roller shaft to rotate together relative to a track roller frame.

Abstract: A steel track chain component, such as a track bushing, may be formed with a carburized portion, a hardface portion, and a core portion. The core portion may be softer than the carburized portion, which in turn, may be softer than the hardface portion. This configuration of the various portions of the component may allow for relatively high wear resistance of the component, as well as toughness. The core portion may be mostly ferrite crystal structure, while the carburized portion and the hardface portions may include martensitic and/or austenitic crystal structure. The carburized portion may be formed by carburizing the track chain component in a heated and carbon rich environment. The hardface portion may be formed by welding a hardface alloy over at least a portion of the carburized portion.

Abstract: A method for manufacturing a component is provided. The method includes providing one or more notches on a surface of the component. Further, depositing a coating on the surface to provide a thickness of the coating on the surface, is performed. The method also includes removing, at least partially, the coating from the surface such that the thickness of the coating over the notches is different from the thickness of the coating on the surface adjacent to the notches.
