The Aegis severe-duty SGR bearing protection ring protects severe-duty motor bearings from VFD-induced shaft currents with a shaft grounding ring ¡ª and from contaminants with an IP56 non-contact isolation seal. The ring is suited for motors controlled by variable frequency drives in pulp and paper, food, mining, pharmaceutical, water/wastewater, chemical processing and other severe-duty processing applications. It protects bearings from electrical damage known as ¡®bearing fluting¡¯, which can lead to noise and vibration and result in motor failure. The bearing isolator withstands dust and powerful jetting liquids. The bearing protection ring is not suitable for Class 1 (Division 1 or 2, Zone 1 or 2) hazardous areas.
