Garlock SGiAccording to Garlock Sealing Technologies, its new SGi shaft grounding bearing isolator is the first seal to protect bearings from electrical damage, as well as lubricant loss and contamination. The Garlock SGi combines the technologies of the GUARDIAN non-sparking bronze labyrinth seal and the AEGIS shaft grounding ring in a single unit. It also offers:

  • The diversion of harmful currents safely to ground, bypassing the bearings entirely and extending motor life. 
  • The patented AEGIS FiberLock channel, which is permanently built into the isolator, to secure circumferential rows of conductive microfibers, preventing their dislocation and the resulting accidental contamination. 
  • Specially engineered microfibers for flexibility to prevent breakage and ensure that the isolator lasts as long as the motor.
  • An IP56 non-contact isolation seal that withstands dust and powerful jetting liquids, while easily replacing contact lip seals and traditional bearing isolators.
  • The ability to withstand operating temperatures from -22° to 300° F. 
  • Availability for motor-shaft sizes ranging from 0.875 to 6 inches in flanged, flangeless and custom configurations.
  • Suitability for motors controlled by variable-frequency drives, 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.
