Poly-v Belts

In comparison with the traditional V-belt drives, the system with Poly-v belts may achieve a potential higher performance of maximum 50% due to the structure characteristics of the multi-v shape on the running side. Poly-v belt provides a low noise drive with very low vibration thanks to the advantageous features as follows:

  • The drive can be equipped with smaller pulleys and make the driving system as compact as possible for the sake of the high flexibility of Poly-v belts.
  • The thinner body of Poly-v belt makes it possible to drive additional accessories / idlers, when necessary, without affecting belt life
  • Multi-v shape of Poly-v belts ensure a better contact with pulleys on the system that results in low vibration and thus get a noise-free power transmission in most of the industrial applications.

Product Features:

  • High resistance to oil and heat, thus less stretch and long service life
  • High flexibility and spacing saving
  • Suitable for reverse bend drives
  • Trouble free in matching set belts like the traditional ones
  • Suitable for high speed drive of up to 40 m/sec
  • Low down time and thus low belt replacement cost
  • Available either as individual belts or as sleeves
