Stretchy Belt
The Ideal Elastic Belt for Automotive.

THE STRETCHY IS A POWER TRANSMISSION BELT
WITH MULTIPLE LONGITUDINAL RIBS.


The Stretchy belt powers the Front End Accessory Drive (FEAD) of cars and trucks through:

  • FEAD system optimization. 
  • Optimized power transmission.
  • Eliminates need for tensioner. 
  • Retains stable tension throughout product lifetime.
  • Reduced costs and weight.

AUTOTENSION

Our belt is used on a fixed center-to-center distance and automatically maintains systems tension. It does not require any additional tensioner.

It can be installed as a "snap-on" or via an on/off idler.

The belt tension is constant throughout its lifetime.

Its modulus, lower than a standard Poly V belt, reduces tension variations.

FEAD SYSTEM OPTIMIZATION

The Stretchy belt offers simple design and reduced packaging of the FEAD system.
As the expert in its field, Hutchinson has initiated 95% of elastic belt conversions.
As the inventor of the elastic belt, we are considered the worldwide technology expert.

COSTS AND WEIGHT REDUCTION

The tensioner removal allows cost and weight reduction accross the entire system.

OPTIMUM POWER TRANSMISSION

The minimum tension in the system is defined to guarantee power transmission.

Belt tension dispersion is minimized to limit loads on bearings thanks to our patented Polyamide cord, in production since 2000.

These characteristics are combined to reduce power losses on the FEAD system (up to 2g CO2 thanks to transmission system simplification) and to optimize belt and component lifetime.

TENSION STABILITY

The tension remains stable for the entire operating time, even under extreme loads.

The Stretchy belt does not require any additional maintenance.
