Electro Static Technology’s new AEGIST 841 SGR Bearing Isolator Shaft Grounding Ring protects severe-duty motor bearings from harmful VFD-induced shaft currents with a proven shaft grounding ring and from contaminants with an IP56 non-contact seal. IEEE Standard 841-2001 calls for protection against bearing damage by VFD-induced currents in addition to bearing seals. Traditional bearing isolator seals provide only half the protection needed by VFD-controlled IEEE 841 and other severe-duty motors. Designed for long-term total bearing protection, the AEGIST 841 SGR combines a proven shaft grounding ring (in which conductive microfibers completely surround the motor shaft in a protective fiber channel) and a non-contact IP56 bearing isolator that withstands dust, debris and powerful jetting water (providing even greater protection against contaminants than is required by IEEE Standard 841).Get more information from Electro Static Technology.
