AEGIS® bearing protection for VFD AC motors

We supply AEGIS® shaft grounding brushes, which provide superior electrical protection of bearings in variable speed AC motors.

The AEGIS® SGR Conductive MicroFiber™ shaft grounding brush prevents electrical damage to motor bearings by safely channelling harmful shaft currents to ground. Using proprietary Electron Transport Technology™, the conductive microfibers inside the AEGIS® SGR™ provide the path of least resistance for damaging shaft currents, preventing electrical damage to motor bearings and dramatically extending motor life.

The AEGIS® SGR™ grounding brush provides many benefits:

  • Maintenance-free
  • Unaffected by dirt, grease or other contaminants
  • Lasts for life of motor
  • Easily installed in minutes – even in the field
  • Mounts on either end of motor shaft
  • Simple screw-on mounting brackets
  • No machining required
  • We offer three options for shaft bearing protection

AEGIS® SGR™ is suitable for small to medium sized motors up to 10 amps and shaft diameters exceeding 152mm. It is also available in solid and split designs.
