  • Quad-Power® 4 has been developed to replace traditional V-belts on applications where space, weight savings and temperature resistance are required.
  • Extensive testing has shown that Gates Quad-Power® 4 V-belts offer up to 50% higher offer ratings than the wrapped Super HC®.
  • The new upgraded EPDM compound allows the belt to handle extreme temperatures up to +130°C.


  • Notch depth is in proportion to the cross-section to ensure perfect stability
  • Precision-ground sidewalls reduce centre distance variations, vibration and uniform wedging action
  • Flex-Bonded polyester cords for equal load distribution and reduced stress from flexing
  • Fibre-loaded EPDM compound withstands high heat, ozone, sunlight and provides better cord support
  • Double Flex-Weave® textile backing protects the belt against wear – especially when back idlers are used
  • Non self-igniting - the belt will not catch fire from heat build-up, even with severe slippage
  • Static conductive - ISO 1813 and RMA IP3-3


  • No re-tensioning required
  • Reduce wrapped belt drive width up to 50%
  • Increase efficiency up to 3% offer wrapped belts
  • Use smaller diameter pulleys than wrapped belts
  • Moulded notches reduce and evenly distributed thermal and bending stresses
  • Reduce drive maintenance
