Abstract: A track link comprises a body defining a top surface, a bottom surface, a first side surface and a second side surface, a proximate end and a distal end, a first bore adjacent the distal end defining a first longitudinal axis and a second bore adjacent the proximate end defining a second longitudinal axis; wherein either the first bore or the second bore is a blind bore, forming a counterbore configured to house a seal assembly and the counterbore defines a wall that forms an angle with the longitudinal axis of the bore that is greater than zero degrees.

Abstract: A link assembly for a machine is disclosed herein. The link assembly includes a first master link portion, a full track link, and a plug. The full track link is coupled to the first master link portion. The plug is positioned within the full track link and adjacent to the first master link portion. The plug is positioned and shaped to prevent the rotational movement of the first master link portion.

Abstract: An idler assembly includes a cylindrical hub defining an axis of rotation, a radial direction, and a circumferential direction. A stepped circumferential surface of the cylindrical hub has a first radially inner face, and a radially outer cylindrical face. Mounting holes extend radially into the radially outer cylindrical face. A first idler segment is attached to the cylindrical hub, and includes an at least partially flat body having a first planar chain link contacting surface. The cylindrical hub has a first set of metallurgical properties that is different than the second set of metallurgical properties of the first idler segment.

Abstract: A bushing assembly for a track assembly includes a first end element, a second end element, and a central element positioned between the first end element and the second end element. The central element may be interference fit or positioned between the first end element and the second end element, and the central element may include a greater hardness than the first and second end elements. The first end element, the second end element, and the central element form a bushing with a longitudinal opening extending longitudinally through the bushing.
