Abstract

A rolling bearing including a conductive shield and an insulation coating is provided. The rolling bearing assembly includes a fixable bearing ring including a first raceway and a rotatable bearing ring including a second raceway. A roller assembly includes a cage and a plurality of rolling elements are located in the cage and supported to roll on the first raceway of the fixable bearing ring and the second raceway of the rotatable bearing ring. A shield extends between the fixable bearing ring and the rotatable bearing ring. The shield includes a first end connected to the fixable bearing ring, and at least one electrically conductive element extends from a second end of the shield and contacts the rotatable bearing ring. A conductive extension on the first end of the shield is connectable to ground. The insulation coating covers surfaces of the fixable bearing ring outside of the first raceway.
