Decrease Equipment Downtime by Protecting Against Stray Shaft Currents

Improve the reliability of VFD-driven motors, or coupled equipment, by protecting bearings from harmful stray shaft currents with the Inpro/Seal Smart CDR®, the next generation of shaft grounding technology.

Inpro/Seal Smart CDR

Innovative Features. Proven Technology.

The Smart CDR utilizes proprietary conductive filaments to protect bearings from harmful shaft currents by providing a low impedance path to ground, diverting them safely away from the bearings.

Its innovative sleeve provides a consistent contact surface for the conductive filaments, reducing wear and making the Smart CDR less susceptible to grounding ineffectiveness caused by shaft conditions, contamination or conduction inhibiting oxidation.

Features and Benefits

  • Conductive Filaments – provides shaft currents a path to ground, away from the bearings
  • Shaft Sleeve – promotes premium grounding performance through consistent contact with conductive filaments; prevents conduction inhibiting oxidation from forming on the shaft
  • Conductive O-Rings – maintain s conductivity for shaft currents
  • Smart Terminal – connects to the Smart Ground Monitor, providing condition monitoring
