Poly V belt transmits the torque and the power by contact of
the belt rib flanks and the pulley grooves.

The Hutchinson Poly V is a molded belt, its monobloc design guarantees:

Compactness
High power transmission
Operating cost

As a drive belt, the Hutchinson Poly V belt is able to cover a large engine range from light duty to heavy duty machineries (Fitness equipment, gardening, HVAC, Industrial Engines, Energy, Pumps, Mines and Quarries).

The Poly V has been designed with a larger contact surface area than V belts or flat belts with a single cord.
Improved transmission ratio is possible (Poly V 1 : 60 vs V belt 1 : 20). Does away with the need for stepped pulleys.
Reduced diameters (diameters up to 9mm with the H profil compared to 50mm with V belts).
Reduced belt width for a given geometry and the same power transfer.

Moreover, the Poly V can operate in flexion and counter flexion with the following benefits:

A single belt can drive several accessories: serpentine belt drive.

Driving accessories, such as Idlers and drive pulleys from the back of the belt.
