Abstract: A track pad of an articulating track system for a machine is disclosed. The track pad includes a ground engaging portion and a body portion. The ground engaging portion includes a ground engaging surface that engages the ground during operation of the machine. The body portion extends from the ground engaging portion in a direction opposite the ground engaging surface. The body portion includes a roller engaging surface distal to the ground engaging surface. The roller engaging surface is a convex surface that matches the curvature of a roller surface for a roller of the machine.

Abstract: A sealed and lubricated rotatable track engaging element includes a roller and a roller shaft extending through the roller to support the roller for rotation about a major axis. A first thrust surface is fixed relative to the roller, and a second thrust surface is fixed relative to the roller shaft. A seal cavity extends between the roller and the roller shaft and is formed in part by each of the first thrust surface and the second thrust surface, and a thrust washer stack is within the seal cavity and trapped between the first thrust surface and the second thrust surface. The thrust washer stack includes an inner thrust washer contacting the roller to rotate at a first fractional speed of a speed of rotation of the roller, and an outer thrust washer contacting the inner thrust washer and the collar to rotate at a second fractional speed that is less than the first fractional speed.
