FNH Pneumatic Brake

FNH Pneumatic Brake

The FNH pneumatic brake is designed for applications where it is necessary to control the unwind tension, such as paper, fabric or cable reels.

The brake is composed of the static air chamber and the friction disc that brakes the shaft.

It is a brake that is designed for continuous braking thanks to the fact that the brake disc has a radiator with great heat dissipation.



The FNH pneumatic brake is a brake that can be used continuously. This product is characterized by having the air supply through a static chamber and by having great response sensitivity through the regulation of air pressure.

The FNH pneumatic brake is indicated for tension control applications since the friction material is designed to work in continuous friction with very little wear and without generating vibrations or noise.

They are used in industrial unwinders for paper, plastic, textiles, graphic arts, etc. since its main advantage is that it has a great capacity for heat dissipation and also has a very low weight.

The most common assembly is directly to the shaft where the reel to be unwound is located.

We can find some of its main characteristics below:

  • Self-supporting
  • Static air chamber, radial air intake
  • Ability to regulate torque through air pressure
  • High sensitivity
  • Good heat dissipation
  • Reduced weight
  • Torque proportional to pressure
  • Minimum moment of inertia


The FNH pneumatic brake can be used for different types of machinery such as:
