The AEGIS® SGR shaft grounding ring

(bearing protection ring) protects the

life of your motor bearings.

Motors operated by variable frequency drives (VFD) are vulnerable to VFD-induced shaft voltages and bearing currents that can cause premature bearing failure. Once these shaft voltages and high frequency currents overcome the resistance of the bearing lubricant, they discharge through the motor bearings, burning bearing grease. These discharges could also cause pitting, fluting damage to the motor’s bearings and eventual bearing failure. AEGIS® SGR prevents electrical bearing damage by channeling harmful shaft voltages away from the bearings and safely to ground. Using Electron Transport Technology®, the conductive microfibers within AEGIS® SGR provide the path of least resistance and significantly increase engine life.
