Overview
The Gates 3VX1000 is a narrow-section Super HC® molded notch V-belt (Series 9412) engineered for demanding industrial power transmission applications. Constructed with Gates’ proprietary ethylene material and flex-bonded polyester-reinforced EPDM compound, this belt delivers superior performance in high-horsepower, space-constrained drive systems. The 100-inch outside circumference design fits a wide range of industrial machinery requiring reliable, efficient power transfer.
Key Features
- Superior Horsepower Rating: Transmits up to 3× the horsepower versus comparably sized belts
- Molded Notches: Reduce thermal and bending stresses for improved flexibility and longer service life
- Flex-Bonded Construction: Flex-bonded tensile cords vulcanized as one solid unit, making the belt highly resistant to tensile and flexing forces, fatigue and shock loads
- Temperature Range: -70 to 250 deg F operating temperature for year-round reliability
- Precision Manufacturing: Precision-ground straight sidewalls give uniform wedging action and machined belt edge provides maximum sheave-groove contact for even wear and extended belt life
- Oil & Contamination Resistance: Proprietary Flex-Weave® cover protects the belt’s interior from oil, contaminants and heat
