Abstract: A mechanical face seal includes a seal ring, the seal ring including an inner circumferential surface, an outer circumferential surface, and a generally annular body extending between the inner and outer circumferential surfaces. An annular flange projects radially from the annular body to an outer perimeter of the flange and a sealing band is on the annular flange. A slot may extend radially into the seal ring from the inner circumferential surface of the seal ring. A cooling channel may be in and extend generally circumferentially through at least one of the annular body and annular flange.

Abstract: A track link for a ground-engaging track includes an elongate link body having a lower hardness material forming a lower mounting surface for mounting a track shoe, and a sacrificial higher hardness material forming an upper rail surface for contacting rotatable track engaging elements. The lower hardness and higher hardness materials transition at a material interface within the elongate link body, and the material interface is longitudinally non-uniform, such that the sacrificial higher hardness material has a varying depth from the upper rail surface to retard scalloping.
