Continuous return currents can cause serious damage to critical components such as the wheelset roller bearing. Our grounding contacts provide a reliable remedy here by reliably diverting the currents via clear current paths. With our Polyrad grounding contact for mounting on the gearbox, you can rely on extremely long service lives combined with maximum functional reliability. Whether all-carbon grounding contacts with optimum emergency running properties for currentless operation or systems for the highest current densities - all variants are characterized by great material know-how and the possibility of an individual solution that exactly matches the requirement. Our carbon brushes for grounding contacts are of course also available separately as spare parts.
