Genuine, strong, durable sprockets designed for use with high power density Gates Poly Chain Carbon Volt, Poly Chain GT2, and Poly Chain GT Carbon belts.
- Smaller, narrower sprockets save shaft space, keep the load closer to bearing and extend life of reducer.
- Poly Chain GT2 Sprockets keep overhung load below manufacturers' recommendation.
- Precisely manufactured and statically balanced to ISO 1940 (1973) to class G16.
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.

Great belts
Bought these for my lathe. They are much better made than the original. MROSupply charges a very competitive price and the packaging and shipping speed was great.
