The Steel and Aluminum wheels have inner races that are machined and plated for smooth operation, and long life. The outer race and Cup are of a labyrinth construction to keep the dirt out of the inner wheel wheels and the lubrication in between the inner race and Steel Balls. Various lubrication is used in the wheel depending on the application for the wheels. All the friction components are heat treated to a precise hardness to provide longer life and smoother rotation.
