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.

First time customer and I will return! I will tell all of our associates what excellent service we received! You saved us from an ugly situation. With a hefty order needing to go out and the belt broke on our Seiki mill. I called on Friday. I wasn't even expecting shipment until the following Monday or Tuesday but we received our belt the very next day!! The price was fantastic, not to mention FREE shipping!!! I want to thank everyone from the sales agent to the packing and shipping department. Seriously....this was the best service we've received in ages! The "Keiths" Little Cake Machine Shop Edmonton, KY
