Abstract
A bearing includes an inner ring defining an inner raceway, an outer ring defining an outer raceway, and a plurality of rolling elements contacting the inner raceway and the outer raceway to enable relative rotation between the inner ring and the outer ring. A connecting ring is radially between and contacts the inner ring and the outer ring. A chamber is bound at least partially by the connecting ring and one of the two rings. The chamber is at least partially filled with a conductive grease or lubricant to enable electric current to travel between the outer ring and the inner ring at the connecting ring.
