Bearing protection

May 1, 2011

Protecting bearings from electrical damage as well as from lubricant loss and contamination, the Garlock SGi shaft grounding bearing isolator combines the technologies of a non-sparking bronze labyrinth seal and a shaft grounding ring in a single unit. The isolator diverts harmful currents safely to ground, bypassing the bearings entirely and extending motor life. The FiberLock channel permanently secures circumferential rows of conductive microfibers, preventing their dislocation and the resulting accidental contamination of the bearing. The isolator also provides an IP56 non-contact isolation seal that withstands dust and powerful jetting liquids. Withstanding operating temperatures from -22°F to 300°F, the unit is available for motor shaft sizes from 0.875 to 6 in. in flanged, flangeless and custom configurations.
