摘要： A deep groove ball bearing assembly is disclosed. The assembly includes an inner bearing ring defining an inner race, an outer bearing ring defining an outer race, and a plurality of rolling elements supported on the inner race and the outer race. A shaft is supported on a radially inner surface of the inner bearing ring, and a housing is supported on a radially outer surface of the outer bearing ring. The assembly includes a contact surface on at least one of: the inner bearing ring, the outer bearing ring, the shaft, or the housing. The contact surface includes at least one lubrication groove.

摘要： A bearing assembly is disclosed herein. The bearing assembly includes an outer bearing ring including at least one first connection element. The assembly also includes a cap defining an axial portion and at least one radial portion defining a cavity configured to receive the outer bearing ring. The cap includes at least one second connection element configured to mate with the at least one first connection element. The cap is formed from an electrically insulating material to prevent EDM.

摘要： An outer ring for a deep groove ball bearing assembly is disclosed. The outer ring includes a radially inner surface defining a raceway, and a radially outer surface defining a single groove extending between axial ends of the outer ring. The single groove contacts at least one axial end face of the outer ring.

摘要： 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.

摘要： A bearing includes an integrated electrical shunt. The shunt includes electrically conductive fibers sandwiched between two washers, at least one of which is electrically conductive. The fibers are fastened to the electrically conductive washer by electrically conductive epoxy. An outer shield protects the fibers. The outer shield is held to the washers by a drawn cup. The washers, the drawn cup, and the outer shield all have oil drain holes to allow lubricant to flow to the rollers.
