Abstract: A bearing failure detection system includes a thermal protector switch circuit having a wear strip located within an interior of a motor stator. In response to bearing failure or wear above a predetermined magnitude, the motor rotor will shift off its axis of rotation and wear away the wear strip or break the electrically conducting material of the wear strip and activate the stator thermal protector switch circuit and shut down the electric motor. The wear strips assist the thermal protector switch circuit in the identification of a bearing failure and the light rubbing that results therefrom prior to the generation of an electrical burning smell that may otherwise occur after a prolonged period of rubbing.

Abstract: A bearing assembly with a bearing for a rotating element, a bearing assembly housing and a bearing liner inserted between the bearing housing and the bearing liner that has an annular channel that contains an anti-rotation and dampening element and extends from an inner surface of the liner through at least the thickness of the liner.
