Abstract: This invention is directed toward a bearing system for a rotating element, and more particularly directed toward an bearing system which provides an auxiliary bearing system if the primary bearing fails. Transfer of load from the failing primary bearing to one or more auxiliary bearings is initiated by conditions generated by the failing primary bearing such as abnormal heat generation or abnormal torque impulses. Alternately, the invention can be used to prevent primary bearing failure by transferring load to the secondary bearing system if the primary bearing is overloaded. The transfer of load is completely automatic requiring no human intervention. A signal or warning is, however, emitted by the bearing system to notify that loading has been transferred to one or more auxiliary bearings. The invention is directed toward an auxiliary bearing system for tapered roller bearings used in rail cars.
