Shaft Grounding Bearing Isolator

Shaft Grounding Bearing Isolator

The Garlock SGi Shaft Grounding Bearing Isolator is a seal to protect bearings from electrical damage as well as from lubricant loss and contamination. The Garlock SGiis maintenance-free and combines the Garlock Guardiannon-sparking bronze labyrinth seal and the Aegis shaft grounding ring.

The Garlock SGi diverts harmful currents to ground, bypassing the bearings and extending motor life. The Aegis FiberLock Channel built into the Garlock SGi permanently secures circumferential rows of conductive microfibers, preventing their dislocation and the resulting accidental contamination of the bearing. The microfibers allow flexibility to prevent breakage.

Designed for long-term total bearing protection, the SGi also has an IP56 non-contact isolation seal to withstand dust and powerful jetting liquids. It replaces contact lip seals and traditional bearing isolators used in industrial applications and withstands operating temperatures from -22 to 300F. The unit is available for motor-shaft sizes ranging from 0.875 to 6 inches in flanged, flangeless and custom configurations.

It is 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.
