Patent number: 11654983Abstract: 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.
