    Abstract: A saddle for a backing assembly in a rolling mill has non-cylindrical bearing surfaces that accommodate wear by allowing the saddles to self-align. The non-cylindrical bearing surfaces help prevent the needle bearings from being pinched and driven into the gear rings. The non-cylindrical bearing surfaces are provided in different locations such as intermediate the eccentric and eccentric ring or intermediate the eccentric ring and the saddle ring.
