Description
The AEGIS® SGR Bearing Protection Ring prevents electrical bearing “fluting” damage by safely diverting harmful shaft voltages and bearing currents to ground. Using proprietary Electron Transport Technology™, the conductive microfibers inside the AEGIS® SGR provide the most reliable current diversion technology for shaft grounding with a “path of least resistance” to dramatically extend motor life. AEGIS® Shaft Grounding Rings have a warranty of 1 year.
