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.
