Grounding Ring Diverts Shaft Currents Around Bearings

The AEGIS 841 SGR bearing isolator shaft grounding ring protects severe-duty motor bearings from variable frequency drive (VFD)-induced shaft currents. The grounding ring is suited for IEEE 841 motors controlled by VFD. Designed for long-term total bearing protection, it combines a proven shaft grounding ring (in which conductive microfibers completely surround the motor shaft) and a non-contact IP56 bearing isolator that withstands dust and powerful jetting water (providing even greater protection against contaminants than is required by IEEE Standard 841). By diverting VFD-induced shaft currents around bearings safely to ground, the ring protects them from electrical damage known as “bearing fluting” that can lead to noise and vibration and result in motor failure.  The bearing isolator features an Anti-Clog slinger drain system to prevent dirt and debris from plugging up the drain and compromising performance.
