Accessory Poly-V Belts


Product Description

Poly-V belts are designed for the auxiliary transmissions of motorcars, commercial vehicles, industrial vehicles and buses. The increasing number of accessories (air conditioning, power steering, alternators, water pumps, vacuum pumps, etc.) and the operating conditions with temperatures up to 130°C, have made it necessary to update the materials and the production technology.
All Dayco Poly-V belts are made in EPDM material (Ethylene-Propylene-Diene-Monomers) according to the latest standards required by the Automotive market, and guarantee resistance, reliability, quietness and a longer operating life.

The main features are:

  • Flexibility for use on small diameter pulleys
  • Dimensions allowing the use of a single belt for controlling several auxiliary components
  • Power transmission, including with the back of the belt, particularly in case of “double rib”
  • High operating temperature range to guarantee an increased life

In line with the requirements of the automotive sector, Dayco has also developed for the aftermarket the last generation Poly-V belts EPDM3, capable of transmitting a high work load on the last generation models, while keeping the system life constant.
