AEGIS® SGR Solid Rings
For VFD controlled motors


AEGIS® SGR Bearing Protection Rings are designed to divert bearing currents to ground by providing a highly reliable shaft grounding path. The AEGIS® shaft grounding technology prevents bearing "fluting" damage when motors are controlled by variable frequency drives (VFD). The "solid" AEGIS® rings are ideal for OEM installation, motor repair and upgrades to improve reliability.

Description: Standard models include "bracket mount" AEGIS® SGR, conductive epoxy mount, "bolt-through" mounting and even a "press-fit" version that easily presses into a bore. Easy-to-install the AEGIS® SGR is specified for HVAC, pumps, conveyors and any equipment controlled by PWM drives.
