The Garlock SGi combines the proven technologies of the Garlock GUARDIAN non-sparking bronze labyrinth seal and the AEGIS shaft grounding ring in a single unit.

The new Garlock (Canton, MA) SGi Shaft Grounding Bearing Isolator is the first seal to protect bearings from electrical damage as well as from lubricant loss and contamination.  Maintenance-free, the Garlock SGi combines the proven technologies of the Garlock GUARDIAN non-sparking bronze labyrinth seal and the AEGIS shaft grounding ring in a single unit. It is ideally suited for motors controlled by variable frequency drives (VFDs) running pumps, fans, high-speed spindles, and other equipment in “severe-duty” applications such as mining and the processing of pulp/paper, food, pharmaceuticals, chemicals, and water/wastewater. Features include:

• A patented AEGIS FiberLock Channel built into the Garlock SGi that permanently secures circumferential rows of conductive microfibers, preventing their dislocation and the resulting accidental contamination of the bearing. 
• An IP56 non-contact isolation seal that withstands dust and powerful jetting liquids.
• An operating temperature range from –22° to 300° F. 
• Available for motor-shaft sizes ranging from 0.875 to 6 inches in flanged, flangeless, and custom configurations.
