S Bearings, EZO bearings, Bearing Relubriion Services - Can ball bearings conduct electricity?

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 appliions where there is a build-up of static electricity.

HECO All Systems Go - The Importance of Electric Motor Bearings

These bearings don’t require a cage and race in the same way that ball bearings do. Electric motor roller bearings are used for belted appliions with motors 150 HP and above. The surface of the cylindrical shape rolling elements helps to account for the high level of radial load that the belts put onto the bearings.
