The AEGIS SGR™ shaft grounding ring dramatically extends bearing and motor life and increases system reliability by diverting shaft currents to ground. Unlike conventional grounding brushes, the SGR™ is maintenance-free and lasts for the service life of the motor. It works with virtually no friction or wear and works even in dirt, grease, or other contaminants.

• Measuring VFD Induced Shaft Voltages
  

Variable frequency drives (VFD) on AC and DC motors induce harmful electrical voltages on the motor shaft. Once these voltages exceed the resistance of the bearing lubricant, they discharge through the motor's bearings causing fusion craters, severe pitting, fluting damage. Excessive bearing noise and eventually bearing failure is the result. Current diversion in the form of the patented AEGIS shaft grounding is needed to make these motors sustainable.

The new AEGIS SGR™ Bearing Protection Ring™ prevents electrical bearing fluting damage by safely diverting harmful shaft voltages and bearing currents to ground. Using proprietary Electron Transport Technology™, the conductive microfibers inside the AEGIS SGR™ provide the most reliable current diversion technology for shaft grounding with a "path of least resistance" to dramatically extend motor life.
