A track roller shaft comprises a body including a revolved surface defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation. The body also defines a proximate axial end disposed along the axis of rotation, a radially extending hole that is disposed axially adjacent to the proximate axial end, and a guide member receiving pocket disposed axially farther away from the proximate axial end than the radially extending hole.

A track pad may include a base member and a roller path member extending from the base member. The roller path member may include a roller path surface for engaging with a roller of a machine. The roller path member may include a leading side and a trailing side in a direction of travel of the machine. The roller path member may include a hardened region that extends from the roller path surface and a body region adjacent the hardened region. The hardened region may have a greater hardness than the body region. The hardened region may have a uniform depth from the leading side to the trailing side of the roller path member.

A track roller rim is disclosed. The track roller rim may include an outer member including an annular configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation, where the outer member has an inner circumference, an outer circumference, a first axial end disposed along the axis of rotation, and a second axial end disposed along the axis of rotation. The track roller rim may include a first annular inner member, where the first annular inner member is interference fit within the inner circumference of the outer member at the first axial end. The track roller rim may include a second annular inner member, where the second annular inner member is interference fit within the inner circumference of the outer member at the second axial end.

A clamping master track link includes a body that defines a first bore and a second bore, a first aperture disposed between the first bore and the second bore, a second aperture disposed between the first aperture and the second bore, a first strut with a first gap disposed between the first aperture and the second aperture, a second strut with a second gap disposed between the first aperture and the first bore, and a bridge disposed between the second aperture and the second bore. The first bore defines a cylindrical bore surface that is at least partially textured.

A cored wire for hybrid laser cladding includes a hollow metal sheath and a core powder composition. The core powder can include, by weight percent: carbon from about 0.8% to about 1.2%, manganese from about 1% to about 1.4%, silicon from about 0.8% to about 1%, chromium from about 22% to about 30%, titanium from about 0.5% to about 2%, vanadium from about 0.5% to about 2%, boron from about 0.8% to about 1.2%, phosphorus from 0% to about 0.04%, and sulfur from 0% to about 0.03%, the balance of the core powder composition being substantially iron. Components and methods using the cored wire are also disclosed.
