Your Bearings Can Fail from VFD-Induced Shaft Currents
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 Your Bearings with AEGIS
AEGIS® Shaft Grounding Rings are the leading bearing protection technology. They protect bearings by giving shaft voltages a "path of least resistance" to ground, so the shaft discharges through the ring, not the bearing. Unlike other shaft grounding products, AEGIS® rings are long-lived and maintenance-free, and can be installed inside or outside of the motor.
