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.
