AEGIS SGR™
Bearing Protection Ring Kit
for NEMA & IEC Motors
 PROBLEM:
Induced Shaft Currents Damage Bearings
Variable-frequency drives (VFD) controlling AC motors induce electrical currents on the motor shaft and cause damaging electrical discharges in the motor's bearings. The bearing discharges cause pitting, fluting, excessive noise and catastrophic failure. |
 SOLUTION:
AEGIS SGR™ - The World's Most Effective Bearing Protection Technology
The new AEGIS SGR Conductive MicroFiber™ Bearing Protection Ring™ prevents catastrophic motor failure by safely channeling harmful shaft currents away from the motor's bearings to ground. |
Easy to install on motor end bell
- Clears any slinger, shaft shoulder or protrusion
- Adjustable slots adapt to most end bells
- Rigid mounting plate ensures alignment
- Slim design, uses less than 1/2" usable shaft diameter
