Shaft grounding rings

AEGIS SGR bearing protection rings channel harmful VFD-induced shaft currents safely to ground. Unlike conventional grounding brushes, the rings are maintenance-free and work with virtually no friction or wear for the service life of the motor. The ring can be installed in the field without disconnecting the motor from coupled equipment.

AEGIS SGR bearing protection rings channel harmful VFD-induced shaft currents safely to ground. Unlike conventional grounding brushes, the rings are maintenance-free and work with virtually no friction or wear for the service life of the motor. The ring can be installed in the field without disconnecting the motor from coupled equipment. A U-shaped mounting plate fits around the motor shaft, which simplifies installation.
