Poly-V / Serpentine belts are produced for accessory transmissions of cars, commercial vehicles, heavy duty vehicles and buses. With multiple accessories (air conditioning, power steering pumps, alternators, water pumps, vacuum pumps, etc.) and operating conditions with temperatures up to 130°C / 266°F have made it essential to upgrade the materials and construction technology.
Poly-V / Serpentine belts are all made of EPDM (Ethylene-Propylene-Diene-Monomers) material and are compliant with the latest standards required by the automotive industry, guaranteeing resistance, reliability, low noise and a longer service life.
The main features are:
- High bending flexibility for use on small diameter pulleys
- Enginereed with power transmission on both sides of the belts, as per the “DPK” (Double Poly-V)
- Resistance to high operating temperatures for a longer service life
- Adapting to the demands of the automotive sector, Dayco has developed the latest generation of Poly-V / Poly-V serpentine belts for the aftermarket, capable of handling high workloads, while maintaining constant high performance.
