ABSTRACT:
A thrust bearing assembly in which each thrust pad is individually mounted on a deflection element. An embodiment of the invention comprises a rotating bearing runner having a wear resistant face and a stationary bearing carrier defining a plurality of cavities disposed annularly around the carrier. A deflection element, such as a Belleville washer, is disposed in a cavity of the plurality of cavities and a pad is disposed over the deflection element. The pad is at least partially disposed within the cavity. The wear resistant face of the rotating bearing runner contacts the pad.
