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
Designed for efficient power transmission to the vehicle accessory, Dayco has combined raw-edge construction with Dayco’s patented top cogged design to ensure the top performance on vehicles and drives that still utilize V-belts. V-Belt delivers more flexibility and increases airflow around the belt so it runs cooler and lasts longer. Three plies of neoprene impregnated fabric resist heat, oil and grease while a specially-formulated treatment of the polyester cord provides the strength, stability and reliability that are required from one of the most innovative, top-performing V-belts for nearly 30 years.
V-belts are available in different sections (AV10 – AV13 – AV17 types) and guarantee:
- Excellent resistance to repeated flexing
- Low weight
- Use on small diameter pulleys
- High transmission ratios
- Greater friction, less slippage
- Energy saving
- Longer belt life
- Good resistance to heat
- High friction coefficient
Good resistance to oils, greases, chemicals, ozone
