super-HCIn addition to the Super HC® wrapped, narrow section V-belt, Gates markets the Super HC® Moulded Notch V-belt  construction.  Super HC® MN V-belts put more power where high speeds, high speed ratios or small pulley diameters are required, thus offering significant advantages over classical section V-belts. Developed through specialised research, Super HC® MN is highly recommended for use on all industrial heavy-duty, narrow section V-belt drives. The Super HC® MN increased transmission efficiency allows more compact and highly economical drive design. Super HC‚ MN belts are available up to 4750 mm ISO datum lengths.

  • Raw edge construction, ground. 
  • Narrow cross-section. 
  • Moulded notches reduce and evenly distribute thermal and bending stresses. The moulded notch pattern also reduces noise. 
  • Precision-ground straight sidewalls give a uniform wedging action and ensure the belt fits correctly in the pulley grooves. 
  • Allows use of back idlers. 
  • “Flex-bonded” tensile cords are vulcanised as one solid unit making the belt highly resistant to tensile and flexing forces, fatigue and shock loads. 
  • Elastomeric compound protects the belt against heat, ozone and sunlight. 
  • Even with severe slippage, the belt will not catch fire from heat buildup. 
  • Static conductive (ISO 1813)


  • Excellent performance/cost ratio. 
  • More power in the same space or same power in 1/3 to 1/2 less space as compared to classical section V-belts. 
  • Cost and space savings by reducing size of pulleys, bearings, guards and mounts. 
  • Improved belt life reducing expensive maintenance time. 
  • Match system: all sizes meet Gates UNISET tolerances.
