Bearing protection ring directs shaft currents to the ground


The Aegis severe-duty SGR bearing protection ring protects severe-duty motor bearings from VFD-induced shaft currents with a shaft grounding ring — 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.
