AEGIS Bearing Protection

Bearings can Fail

VFD-Induced Shaft Currents Can Kill Your Bearings!

VFDs allow large energy savings and precise control. But they also generate electric voltages on motor shafts. These shaft voltages can discharge through the bearings, causing pitting, fluting, and eventual bearing failure.

Protect Motor Bearings with AEGIS® Bearing Protection Rings

By channeling VFD-induced discharges safely to ground, AEGIS® Bearing Protection Rings prevent electrical bearing damage. Proven in over a million installations worldwide, they provide unmatched protection of motors and coupled equipment from electrical bearing damage, motor failure, and unplanned downtime.
