Split-Ring Bearing Protection Ring with Conductive Epoxy Mounting
July 28, 2010
Developed for fast, easy field installation without detaching coupled equipment, the Split-Ring kit offers 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 channel. The unique channel design not only prevents the microfiber brushes from loosening or falling out, but also protects them from breakage. When used by HVAC service contractors, motor repair shops, and plant maintenance departments, the conductive-epoxy-mounted bearing protection ring prevents bearing noise, downtime, and costly motor repairs/replacements. In addition to the ring, the kit contains engineered silver-filled conductive epoxy. The ring is maintenance-free and lasts for the life of the motor. It works with virtually no friction or wear, regardless of motor RPM, and is unaffected by dirt, grease, or other contaminants.
