Accessory Poly-V Belts

SKU: PK Category:

Description

The Poly-V belts are produced for accessory transmissions of cars, commercial vehicles, heavy duty vehicles and buses. The increase in the number of accessories (air conditioning, power steering pumps, alternators, water pumps, vacuum pumps, etc.) and the operating conditions with temperatures up to 130°C have made it essential to upgrade the materials and construction technology.

The Dayco Poly-V belts are all made of EPDM (Ethylene-Propylene-Diene-Monomers) material in compliance with the latest standards required by the automotive industry, guaranteeing resistance, reliability, low noise and long service life.

The main features are:

  • Highly flexible for use on small diameter pulleys
  • Power transmission also with the back of the belts, in particular in the case of the “DPK” (Double Poly-V)
  • Resistance to high operating temperatures for longer service life

In line with the demands of the sector, Automotive Dayco has also developed for the Aftermarket the latest generation of Poly-V belts capable of handling high workloads, while maintaining constant high performance.

In addition to the traditional transmission systems equipped with Poly-V belts and tensioners, Dayco offers a product line of elastic poly-v belts for both OE and Aftermarket applications: designed for some engines with fixed centre distances and limited development, these belts do not require external tensioning systems (tensioners).

Installation requires special tools that allow the belt to be correctly positioned on the pulleys.
