Schunk Transit Systems offers a broad portfolio of grounding solutions for railway vehicles. Proven earthing contacts ensure safe current return and protective earthing. They are available in different versions for all common installation situations and interfaces - axially at the axle end or radially on the gearbox. Thanks to their high quality and optimised materials, these earthing contacts are characterised by extremely long service lives and thus maximise the service life of your wheelset earthing. In addition to these classic earthing contacts, Schunk's patented Carbon Fibre Grounding system (CFG) has become particularly well established. It has been developed specifically for diverting stray shaft currents and provides effective protection against bearing damage in motors and gearboxes. The use of conductive carbon fibres reliably dissipates interfering shaft currents. Whether for current return, protective earthing or targeted shaft earthing: With decades of experience and a broad repertoire of earthing systems, Schunk is the reliable partner of railway manufacturers and operators worldwide.

Safe shaft earthing is also essential in industrial electric motors. Schunk Carbon Technology supplies earthing brushes and modular earthing systems based on high-quality carbon materials for this purpose. They conduct shaft voltages specifically to defined earthing points and thus protect bearings from damage caused by micro arcs. The result: reduced downtimes and extended system running times.

Schunk Mobility offers an innovative assembly for shaft earthing to meet the requirements of electromobility. This not only reliably protects against bearing damage, but also reduces high-frequency interference (up to 50 MHz) thanks to its EMC-effective properties. The metal-graphite material used ensures constant electrical conductivity and mechanical stability - even under high loads in the automotive sector.

With a modular product portfolio and in-depth materials expertise, the Schunk Group offers highly effective earthing solutions for rail, industry and e-mobility through its Transit Systems, Carbon Technology and Mobility business units. Whether classic earthing contacts, modern carbon systems or EMC-optimised assemblies - Schunk supplies precisely coordinated solutions that meet the highest safety and quality standards.

If you want to reliably dissipate shaft currents, avoid bearing damage and at the same time increase operational safety, Schunk is a partner with comprehensive expertise in electrical earthing.
