split-ring AEGIS bearing protection ring

The split-ring AEGIS bearing protection ring protects AC motor bearings from electrical damage by safely grounding shaft currents induced by variable-frequency drives (VFDs). The unit has a 360-deg. circumferential inner ring of conductive microfibers permanently secured in place by the firm’s patented FiberLock channel, which prevents the microfiber brushes from breaking, loosening, or falling out. The kit includes engineered silver-filled conductive epoxy for mounting the ring. After removing the paint from the area of the motor end bell where the ring is to be installed, the installer mixes the epoxy resin and activator and applies the adhesive to the back of the ring. Next, the ring is positioned and centered around the motor shaft, and held in place to allow the adhesive to set. The entire procedure, including cleaning the end bell, takes about 10 minutes and can be performed without detaching the coupled equipment. Unlike conventional shaft-grounding brushes, the ring is maintenance-free and lasts for the life of the motor. It experiences virtually no friction or wear, regardless of motor speed, and is unaffected by dirt, grease, or other contaminants.
