Abstract
A process for applying one or more inner races on a shaft or a hub of a rolling bearing unit that allows the individual components to be produced with relatively wide tolerances. It is particularly useful in a wheel bearing. The process includes determining the force displacement characteristic on the bearing elements at stages of applying the one or both bearing inner races to the hub at the time the first applied bearing race contacts a stop or shoulder on the hub and then during the cold forming of a collar on the hub securing the inner races on the hub. The force displacement characteristic is monitored and may be compared with predetermined stored values.
