Aegis SGR conductive microfibre shaft grounding ring

The Aegis SGR conductive microfibre shaft grounding ring is designed for predictive and preventive maintenance programs on VFD-controlled AC motors and large DC motors. By protecting bearings from electrical damage, the SGR extends motor life, preventing bearing noise, downtime, and costly motor repairs and replacements. The Aegis SGR prevents bearing damage by channelling shaft currents to ground.  Conductive microfibres inside the SGR provide the path of least resistance, allowing these shaft currents to discharge safely to the motor frame.

Preventing shaft current damage (in many cases for the life of the motor), the Aegis SGR simplifies predictive and preventive maintenance programs for motor repair shops, maintenance contractors, HVAC service contractors and in-house maintenance departments.  Unlike conventional shaft grounding brushes, the SGR’s conductive microfibres work with virtually no friction or wear; are unaffected by dirt, grease, or other contaminants; and last for the life of the motor, regardless of speed. A mounting kit simplifies installation of the SGR on any NEMA or IEC motor and provides clearance for motors with shaft shoulders, slingers, bearing caps or end-bell protrusions. Secured with three mounting screws and standoff posts, the entire assembly covers less than 12 mm of the motor shaft.
