Construction • Optimised notch profile reduces and evenly distributes thermal and bending stresses and increases energy efficiency. Notch depth is in proportion to the cross-section to ensure perfect stability. • Precision-ground sidewalls give a uniform wedging action. • Fibre-loaded elastomeric compound withstands heat, ozone and sunlight and provides better cord support. • Flex-bonded polyester tensile cords are vulcanised as one solid unit, increasing the belt’s resistance to tensile and flexing forces. • Double Flex-Weave® textile backing protects the belt against wear - especially when back idlers are used. • Cross-cords improve belt stability. • Even with severe slippage, the belt will not catch fire from heat build-up. • Static conductive (ISO 1813) and can as such be used in the conditions described in the Directive 94/9/EC - ATEX. Advantages • One of the most powerful belts in Gates’ industrial V-belt range. • Excellent performance/cost ratio. • Increased transmission efficiency as compared to other V-belt types. • Cost and space savings. • Savings on pulley cost. • Maximum belt life reducing maintenance time. • Match system: all sizes meet Gates UNISET tolerances, they can be installed without matching.

It has been developed to replace traditional V-belts on applications where space and weight savings are critical: Quad-Power® II has a very high power capacity and can be used on small pulley diameters. Extensive testing has shown that Gates Quad-Power® II V-belt offers up to 15% higher power rating values than previous generations, ensuring the same service life. Improved resistance to outside bends allows the use of back idlers. The unique notch profile makes the belts run smoothly in the pulley grooves.
