Baldor Electric Company announces the availability of bearing protection ring technology as an option on Baldor Reliance motors. Aegis SGR Bearing Protection Ring technology, manufactured by Electro Static Technology, protects motor bearings from shaft currents induced by adjustable speed drives. Electro Static Technology guarantees that any new motor up to 100 hp/75 kW will not fail from electrical bearing fluting damage for the life of the motor when the Aegis SGR Bearing Protection Ring is installed in accordance with the manufacturer’s installation instructions. If electrically induced fluting damage does occur, Electro Static Technology will replace the motor bearings free of charge. The guarantee is subject to the terms and conditions of the Aegis SGR Guarantee Program. Aegis SGR rings are specified by many HVAC, pump and conveyor manufacturers to mitigate adjustable speed drive circulating currents and prolong bearing life. The rings are available as an option on Baldor Reliance custom motors, or they can be installed on a stock motor in Baldor’s Mod Express Department and shipped within a few days.
