Shaft ground isolator for VFD controlled motors

SGi® bearing isolators are optimized for shaft grounding and excellent bearing protection. SGi® bearing isolator is the best solution for motors. Country of Origin: United States

Features / Benefits
  • Uses less electricity than contact lip seals
  • Compatible with safety and industrial manufacturing standards
  • Non-contact engineering labyrinth design reduces bearing drag
  • Lifetime bearing protection will extend mean time to failure (MBTF)
  • Extend bearing life
  • Stable sealing performance
  • No wear parts
  • Engineered labyrinth design will discharge contaminants and maintain IP56-rated bearing lubrication
  • No wear parts means sealing performance does not decrease over time
  • Reduced mean time to repair (MTTR) during retrofit
  • Avoid servicing shaft grooves
  • Avoid servicing sealed enclosures
specification
  • AEGIS® Shaft Grounding Technology
  • Exceeds IEEE 841-2001 standard
  • IP 65-66 rating according to NEMA MG 1-2003, see SGi® configuration table
  • Bronze construction according to API 610 (standard)
Configuration:
  • With flange (split and integrated)
  • No blue (one-piece)-does not stick out of the shell surface
  • Surface mount (separate and integrated)-suitable for motors with narrow radial gaps
application
extra information:
Combination element

Patented combination element prevents rotor and stator contact. The combination element also prevents the parts from being separated during operation, otherwise it may cause premature failure. All KLOZURE metal isolator designs cover combination components.

Shaft Grounding Technology

AEGIS® shaft grounding technology allows SGi® to handle stray currents in the motor. Garlock works with EST (Electro Static Technology) to achieve the best electrical protection and best bearing protection in a single seal (ie, SGi®).
