AEGIS® Bearing Protection - Why Shaft Grounding?


Best Practices

General recommendations: For induction motors either foot mounted, c-face or d-flange mounted motors with single row radial ball bearings on both ends of the motor. Motors may be installed either horizontally or vertically.

  • Install one AEGIS® SGR Bearing Protection Ring on either the drive end or the non-drive end of the motor to discharge capacitive induced shaft voltage.
  • AEGIS® SGR may be installed either internally or externally.
  • Use AEGIS® Colloidal Silver Shaft Coating (PN# CS015) on motor shaft where fibers touch.

Product recommendation: AEGIS® SGR
