Abstract: A vapor compression system including a motor having a housing and a shaft having an axis, the shaft urgable into rotational movement by the motor for powering a system component. A primary bearing and a secondary bearing are positioned in the housing for rotatably supporting the shaft, the primary bearing rotatably supporting the shaft during normal system operation. A first bearing stop and a second bearing stop are positioned on opposite sides of the secondary bearing for transmitting axial forces generated along the shaft for reaction by the motor housing during abnormal system operation. At least a portion of corresponding surfaces of each of the first bearing stop and the second bearing stop facing the secondary bearing have a protective overlying layer of material applied thereto.
