Abstract: An electrically conductive assembly for preventing current flow through the raceways of a bearing includes a mounting ring disposeable within a retention groove of an outer member or a bearing outer ring and is formed of an electrically conductive elastic material. The mounting ring has two circumferential ends spaced apart and is deflectable inwardly such that the two circumferential ends displace generally toward each other to reduce the outside diameter of the ring for installation into the retention groove. An arcuate conductor has an outer radial end attached to the mounting ring, an inner radial end engageable with the shaft or the bearing inner ring and two circumferential ends spaced apart to define an arcuate gap when the conductor is installed about a shaft or a bearing inner ring. An electrically conductive path extends between the shaft and the outer member through the arcuate conductor and the mounting ring.
