Grounding brushes for port solutions

Copper graphite grounding brushes are essential for safely discharging unwanted electrical currents in port installations. Drives and frequency converters generate parasitic currents that, without proper grounding, can flow through bearings and shafts. This causes sparking, accelerated bearing wear and ultimately costly failure of port installations. Copper graphite combines high electrical conductivity with the self-lubricating properties of graphite, allowing copper graphite grounding brushes to function durably, stably and with low maintenance, even under the demanding conditions that ports bring.

For precise positioning and constant contact pressure on the grounding brush, the Lubricating Brush Holder GH812 is used, which is fully compatible with copper graphite grounding brushes. Together they form a reliable grounding solution that protects bearings in port installations against harmful parasitic currents, prevents bearing wear and significantly reduces maintenance costs.
