Inpro/Seal Current Diverter Ring (CDR) technology protects your motor bearings and coupled equipment from damaging electrical currents so you can maximize equipment reliability, reduce costly maintenance and minimize unscheduled downtime. Variable Frequency Drives can create stray currents that run along the shaft and discharge through the motor bearings and bearings of coupled equipment causing fusion craters, pitting, frosting and fluting. The Smart CDR grounds shaft currents that cause bearing damage and premature motor failure. On severe duty applications, The Smart Motor Grounding Seals (MGS) provides complete bearing protection against shaft currents, contamination ingress and lubrication loss. The next generation of Smart Shaft Grounding from Inpro/Seal, combines proven technology with innovative new features, providing solutions to problems that limit other technologies.
