Electro Static Technology: Motor Bearing Protection Ring Kit

October 25, 2010


The split-ring Aegis™ bearing protection ring with conductive epoxy mounting is designed to simplify the protection of bearings in VFD-driven motors. Developed for fast, easy field installation without detaching coupled equipment, the kit offers the long-term protection of ac motor bearings from electrical damage, providing a path of least resistance and safely channeling VFD-induced bearing currents to ground. The unit has a 360-degree circumferential inner ring of conductive microfibers permanently secured in place by the patented Aegis FiberLock™ channel. In addition to the ring, the kit contains engineered silver-filled conductive epoxy. After removing the paint from the installation area of the motor end bell, the installer mixes the epoxy resin and activator, applies the adhesive to the back side of the ring, centers the ring halves around the motor shaft, and holds them in place to allow the adhesive to set. According to the manufacturer, the ring is maintenance-free and lasts for the life of the motor.
