Abstract:
A bearing includes an inner ring having an outer surface defining a first pocket therein. The surface of the first pocket can be provided with a first conductive coating. The bearing includes an outer ring concentric with and radially outward from the inner ring. The outer ring has an inner surface defining a second pocket therein, and a surface of the second pocket can be provided with a second conductive coating. A plurality of rolling elements are disposed between the inner ring and the outer ring. An electrically-conductive shunt ring assembly couples the inner ring to the outer ring and is configured to inhibit electrical current passing between the inner ring and outer ring from passing through the rolling elements. The shunt ring assembly is sized and configured to enable lubricant to flow freely through the bearing. In some embodiments, the shunt ring is a conductive snap ring.
