Electro Static Technology announces that its AEGIS SGR Bearing Protection Ring improves the reliability of HVACR systems by dramatically extending motor life.  The AEGIS SGR prevents bearing noise and costly motor repairs and downtime by protecting bearings from electrical damage for the life of the motor, the company said. It is ideal for OEM motor and fan manufacturers, repair shops, HVACR service contractors, and in-house maintenance departments. In addition, it can be easily installed as part of a preventive maintenance program.

The AEGIS SGR is easily installed by sliding the ring over either end of the motor shaft and locking it in place with simple screw-on mounting brackets.  Because no machining is required, the SGR can be installed in minutes — even in the field.

Unlike conventional shaft grounding brushes, which wear out quickly and lose their effectiveness, the AEGIS SGR’s conductive microfibers work with virtually no friction or wear and last for the life of the motor, with no RPM limitations, the company said.  Maintenance-free, the AEGIS SGR is unaffected by dirt, grease, or other contaminants and provides the longest-lasting protection available.

The SGR is available in standard sizes to fit AC motors ranging from 1 to 1500 HP with shaft diameters from 0.311” to 6.020” (8 mm to 153 mm).  Larger sizes are available for shafts with diameters greater than 6”.
