Abstract
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.
