Helwig Carbon shaft-grounding assembly protects against premature bearing failure


Helwig’s grounding assemblies divert static and induced electrical currents in motor shafts away from the bearings, protecting them from pitting and potential damage.

Helwig Carbon has launched a line of shaft grounding systems to protect motors from bearing failure, a major cause of motor downtime. The stock kits fit most motors and various shaft sizes. They are easy to install, maintain, and work effectively in contaminated environments. Helwig’s grounding assemblies divert static and induced electrical currents in motor shafts away from the bearings, protecting them from pitting and potential damage.

Several methods are available to reduce or eliminate the path the induced electrical currents can travel. Among these, the company says Helwig’s Bearing Protector is a best choice. The Helwig Bearing Protector will give years of service while maintaining low shaft potential, minimizing a chance of having stray currents pass through the bearings. The Bearing Protector is a cost effective way to keep shaft voltage to a minimum.

The company has over 85 years experience manufacturing precision machined carbon brushes, vanes, bearings, bushings, and seals. Helwig is one of the last American owned carbon companies. They are known for fast, reliable service, high quality workmanship, and on-time deliveries.
