A woven plastic conductive fabric is used as an alternative to existing systems for providing positive, continuous, electrical grounding of a rotating shaft. A rotating shaft typically runs in lubricated bearings which can interfere with shaft grounding by causing intermittent insulation of the shaft. This can even cause pitting of the bearing balls by arcing. Shaft grounding is well known in copiers, etc., using copper bronze wiper shaft contact grounding, or the like. However, this can have life problems with wear, and necessitate an extra assembly step.
