In 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.

Identification
Durable yellow marking indicating type and dimensions.

Construction

• Raw edge construction.
• 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. ? Back idlers can be used.
• ?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).

Advantages

• 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, they can be installed without matching.
