Shaft Grounding Devices, Shaft Voltage Testing, & Accessories

Motors operated by variable frequency drives (VFDs) are vulnerable to VFD-induced shaft voltage and bearing current that can cause premature bearing failure.

AEGIS®️ Rings protect motors by channeling stray current away from the bearings and safely to ground, preventing bearing failure and costly downtime.
