The AEGIS SGR-24.9-3FH shaft grounding ring protects electric motor bearings from variable frequency drive-sourced shaft voltage and bearing current by employing 360° of proprietary conductive microfibers in a multiple-row design for 100% circumferential shaft contact. This solid ring features a 2.10-inch outer diameter, 0.295-inch maximum thickness, and fits shaft diameters from 2.10 inches, utilizing bolt-through mounting with 6-32 screws for secure installation. Rated to discharge high-frequency currents up to 2 amps, it offers virtually zero friction with less than 0.001-inch wear over 10,000 hours and a 200,000-hour wear life. Key advantages include low-to-no maintenance, environmental adaptability to temperature and humidity, and a patented FiberLock™ channel that secures fibers for optimal grounding performance, ensuring reliable bearing protection for motors up to 300 HP.
