Carbon fiber contact for shaft grounding

Schunk has developed a product that is proven to safely transfer parasitic current through a rotating shaft via way of carbon fiber grounding.  Without a low impedance path parasitic current will transfer through ball bearings causing pitting and leading to high temperature bearing faults. Using a proprietary coating, Schunk can utilize the high surface area of a carbon fiber strand as a conductive path for high frequency current. This creates hundreds of individual connection points with the ground shaft and utilizes the skin effect principal to reduce electrical impedance.
