AEGIS® Bearing Protection - Why Shaft Grounding?


Best Practices

  • Install one AEGIS® Bearing Protection Ring, drive end preferred, to protect bearings in attached equipment (gearbox, pump, fan bearing and encoder, etc...).
  • AEGIS® Ring can be installed internally on the back of the bearing cap or externally on the motor end bracket.
  • Colloidal Silver Shaft Coating PN CS015 is required for this type of application.

Product recommendation:

Bearings in attached equipment may be at risk from VFD induced shaft voltage unless AEGIS® Shaft Grounding is installed.
