Shaft Grounding Brushes

The new AEGIS® SGR Conductive MicroFiber™ shaft grounding brush prevents electrical damage to motor bearings by safely channeling harmful shaft currents to ground. Using proprietary Electron Transport Technology™, the conductive microfibers inside the AEGIS® SGR provide the path of least resistance for damaging shaft currents, preventing electrical damage to motor bearings and dramatically extending motor life.

Not only is the AEGIS® SGR the world’s most effective grounding brush, it offers the longest lasting protection available.
