Electrically insulated roller bearing, has electrically conductive sheet arranged in region of side surface of inner or outer rings between two insulating layers, where electric contact is made from inner space to control unit by sheet

摘要

The bearing has an insulating layer (13) arranged on an inner ring and/or on an outer ring (2). An electric contact is made from an inner space of the bearing to a control unit of the bearing via an electrically conductive sheet (16). The conductive sheet is arranged in a region of a side surface (14) of the inner ring or the outer ring between the insulating layer and another insulating layer (18). The conductive sheet includes a support layer, which is provided between an adhesive layer and a carbonaceous metallic hard layer.
