  • An explanation of the electrical conductivity of bearings

    Steel ball bearings can conduct electricity whereas full ceramic bearings, hybrid ceramic bearings and plastic bearings are non-conductive. In a steel bearing, current passes from inner ring to outer ring via the balls. This often occurs in electric motors and generators and applications where there is a build-up of static electricity.
