• Pitch: 8mm
• Pitch Diameter: 4.01"
• Belt Width: 21mm
• Number of Teeth: 40
• Bore or Bushing: 2012
• Bore Range: 1/2" - 2 1/8"
• Material ID: 77692140

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.
