What is the FNC pneumatic brake?


The pneumatic brake FNC is a versatile and efficient solution for applications requiring reel control in industrial processes.

This brake stands out for its ability to operate continuously and its sensitive response thanks to air pressure regulation.

FNC pneumatic brake characteristics

Air supply through static chamber: These brakes are supplied with air through a static chamber, which ensures a constant and reliable supply.

High response sensitivity: Brake response is highly sensitive and is achieved by precise regulation of the air pressure.

High-performance friction material: They are designed to operate in continuous friction, with minimum wear and without generating annoying vibrations and noises.

Proportional control of braking torque: Braking torque is directly proportional to air pressure, allowing precise and adjustable control of the torque absorbed by the brake.

FNC pneumatic brakes applications

These brakes find their use in a variety of industrial applications and are particularly suitable for tension control. Some of the most common applications include.

Industrial unwinding machines: FNC pneumatic brakes are essential on paper, plastic, textile and graphic arts unwinding machines. Their ability to maintain constant tension on the material is essential in the production of high quality rolls and sheets.

Elastic couplings: In addition to braking axles, the FNC brakes are also available in versions that allow elastic couplings to be fitted. This extends their versatility in applications where additional control is required.

Components of a FNC pneumatic brake

Static air chamber: Where the air supply for the operation of the brake is received.

Friction disk: The friction material is fixed on this disc, which is connected to a chain or pulley. There is also a version that allows the mounting of an elastic coupling.

Heat dissipation radiator: The brake disc incorporates a high-capacity radiator to dissipate the heat generated during continuous braking, ensuring optimum performance.

Mounting and Transmission

The most common assembly of the FNC pneumatic brakes is realised via belts, chains or gears, allowing effective integration into power transmission systems.

Highlights of the FNC pneumatic brake


  • High sensitivity: The FNC pneumatic brake is highly sensitive and responds quickly and accurately to variations in air pressure. This ensures precise control over braking torque.
  • Torque proportional to pressure: The braking torque generated by these brakes is directly proportional to the air pressure applied. This allows the braking force to be easily adjusted and controlled according to the specific needs of the application.
  • Minimal inertia: FNC brakes have minimal inertia, which means they can stop and start quickly. This is essential in applications that require frequent speed changes.
  • Good heat dissipation: The brakes are designed with high-capacity radiators that allow effective dissipation of heat generated during continuous braking. This ensures optimum performance and a long service life.
  • Reduced weight: FNC air brakes are lightweight compared to other braking solutions, making them easy to install and operate.
  • Axles in different positions: These brakes allow braking of axles in different positions, making them versatile and suitable for a variety of machine configurations.
  • Compact mounting: Compact mounting capability facilitates the integration of brakes into transmission systems and industrial machinery.
  • Self-supporting: FNC air brakes are self-supporting, which means that they do not require additional support structures, simplifying installation.
  • 0 to 5.5 bar regulation: The brakes can be adjusted in a pressure range from 0 to 5.5 bar, allowing precise adaptation to the braking requirements of the application.
  • Continuous friction: These brakes are designed to operate in continuous friction, which minimises wear and ensures stable operation without generating vibrations or disturbing noises.
