THE INDUSTRY'S BEST.

With patented, carbon tensile cord design for high-torque, low-speed drives, Gates engineers were the first in the world to incorporate a high fatigue-resisting carbon fiber tensile cord into the belt, which is made of a new polyurethane compound. Consequently, Poly Chain GT Carbon quickly became the most powerful line of synchronous belts on the market, providing a maintenance-free, energy saving, and environmentally friendly operation, offering an excellent alternative to roller chain and gear drives.


Features and Benefits
  • Keep overhung load below manufacturers recommendation.
  • Full split in bushing allows for easy installation and removal.
  • Precise sprocket design produces positive, press fit to shaft.
  • Re-work services have turnaround time.
  • Warning: Do NOT use these sprockets with rim speeds in excess of 6, 500 fpm.
