Bearing Isolator has become the standard sealing solution on IEEE-841 motor and for some other critical equipments. And recent years, more and more OEMs, such as manufacturers of mining motor, bower and compressor, are paying more attention to the EDM problems with the bearings. Electric erosion has become the main cause of motor bearing failure, and it is not easy to detect in the early stage, and gradually the motor vibration and noise become greater, eventually leading to unexpected shutdown.   

If install both the Bearing Isolator and the shaft grounding rings, it will need much space for the two products. Both of them are necessary for some critical applications.  Now BRS has solve the installation problem by issued a combined design of Isolator with shaft grounding ring. With the same standard length of Bearing Isolator, we mounting the conductive brushes on the stator part of Isolator. Also the rotor part of Isolator will keep dust and water out, protect the conductive fiber from contaminated and leading to fast wearing out. For the inner side, we also can use simple design to prevent the grease contacting the conductive fiber, which will lowering the conductivity of the fiber.

Some leading motor manufacturers have tested this combined design of Isolator and shaft grounding ring several years ago. Now this new product has come to mass production stage. In the future, this unique invention will help more customers to strength their competitiveness in the market. BRS will continue to invest in new technology to offer first-class products to global customers.
