Undercarriage track shoe for mobile earthmoving machine

An undercarriage assembly for a mobile machine includes a continuous track having a plurality of mated track links that can translate with respect to the machine. Each track link may include a shoe portion and a body portion. The body portion includes a plurality of projecting pin lugs each having a pin bore to receive a bin and link adjacent track links together. The pin lugs can include a pair of sprocket lugs for making rolling contact with a sprocket, a pair of roller lugs for making rolling contact with a plurality of rollers, and a side lug having a protruding shoulder to assist in aligning the plurality of rollers.

Undercarriage assembly and track links for assembly

A seal ring for a seal assembly includes a body and a seal flange. The body is generally cylindrical and extends along a longitudinal axis between a load end and a seal end. The seal flange is disposed at the seal end of the cylindrical body. The seal flange circumscribes the body and projects radially from the body to a distal perimeter of the seal flange. The seal flange includes a sealing face which is annular and disposed adjacent the distal perimeter. The seal ring is made from an alloy that includes between 8 percent and 13 percent by weight of iron, between 2 percent and 3 percent by weight of silicon, between 13 percent and 14 percent by weight of chromium, and at least 65 percent by weight of nickel.
