1. A track roller member comprising:
a body including a revolved configuration defining an axis of rotation, a radial direction, and a circumferential direction disposed about the axis of rotation, the body defining
a proximate axial end disposed along the axis of rotation and a distal axial end disposed along the axis of rotation; and
a half-tread portion including a first track interface region including an interface surface that is disposed proximate to the distal axial end and extending axially, that is configured to contact less than the full axial-direction width of an inboard portion of a track link and to bear a force, from the track link, that is primarily directed radially inwardly, and defining a first aperture disposed axially between the first track interface region and the proximate axial end,
wherein the force creates a contact pressure.
