                       Install AEGIS® Ring on opposite end of insulation

For horizontally mounted motors with single row radial ball bearings on both ends of the motor:

  • Non-Drive end: Bearing housing must be isolated with insulated sleeve or coating or use insulated ceramic or hybrid bearing to disrupt circulating currents.
  • Drive end: Install one AEGIS® Bearing Protection Ring .
  •      Note: The recommendation above is the preferred configuration for most applications. Contact sales@est-aegis.com with any questions.
  • AEGIS® Ring can be installed internally on the back of the bearing cap or externally on the motor end bracket.
  • Use AEGIS® Colloidal Silver Shaft Coating (PN# CS015) on motor shaft where fibers touch.
