Proven Shaft Grounding Solutions - Maintenance Free - Easy to Install
The AEGIS™ SGR shaft grounding ring dramatically extends bearing and motor life and increases system reliability by diverting shaft currents to ground. Product line includes the AEGIS™ iPRO™ for large medium voltage motors, turbines and generators; the conductive epoxy mounted split and no-split AEGIS™ SGR Bearing Protection Ring that eliminates the need to drill into the motor; and the new AEGIS™ Severe Duty SGR for extreme conditions. AEGIS™ shaft grounding ring technology is maintenance-free and provides proven bearing protection from electrical bearing "fluting" damage.

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.
