Ground contacts for all installation situations

Grounding Systems for Railroad Applications

Permanently in use for you - grounding contacts with extremely long service lives. Grounding contacts must work reliably for the longest possible period. Schunk offers durable solutions for all common installation situations and interfaces. Maximize the service life of your wheelset grounding. Only with a perfectly matched grounding system are return, safety and signal currents safely and reliably discharged. Grounding systems must work reliably for the longest possible period. These grounding systems or grounding contacts are mounted either at the end of the axis (axial) or at the gear unit (radial). At Schunk, such solutions have been established for years and are part of a large repertoire. Therefore, it is no coincidence that leading vehicle manufacturers in the rail/traction sector rely on grounding systems from Schunk - because with our technology, we have revolutionized the transmission of signal currents and ensured new dimensions in maintenance intervals.

Effective protection of your drive systems against vagrant shaft voltage

Shaft Grounding Systems against Shaft Voltage

Bearing or gear damage caused by shaft stress can lead to costly vehicle fleet failures. Extend the service life of your trains with Schunk's patented Carbon Fiber Grounding (CFG) systems: The shaft grounding systems made of carbon fiber reliably divert vagrant shaft currents and safely protect against damage to bearings in motors or transmissions.

Your problem:

Vagrant shaft currents in directionally controlled AC motors lead to

bearing damage in motors or gearboxes
extreme noise generation
increased heat generation within the affected bearings
costly (unplanned) train stoppages

Our solution:

The patented carbon fiber grounding systems from Schunk

reliably divert vagabond shaft currents
effectively protect against expensive bearing damage
are resistant to strong vibrations
can usually be retrofitted without complications
