Bellows Type Air Springs - application of the bellows as a power element

Bellows Type Air Springs have successfully solved vibration and noise problems in many industrial applications.

They are also frequently used in vehicles as seat suspensors and elements to provide vibration and shock isolation. In these applications, the air spring characteristic can be controlled by changing inner overpressure.

This allows to maintain a permanent clearance between the road and the bottom of the vehicle even if the load of the vehicle changes (trucks, lorries, buses).

Air spring can also be advantageously used as air actuators in many applications, including: Lifting platforms, jacks, pressing devices for paper machines, tensioning devices for belt conveyors, clamping devices for industrial gluing operations, car and truck clutches and brake shoes control devices and many others. The bellows are an important mean for eliminating of vibrations of engineering technologies.

RUBENA Type Air Spring

A complete air spring consists of a corrugated air spring body made of rubberized fabric, two clamping rings, the top clamp plate with air inlet, the bottom plate and centre rings. The plates are designed to be attached to nonresilient and resilient-mounted parts of the vehicle (device).

DUNLOP Type Air Spring

The complete DUNLOP Type Air Spring consists of a corrugated body made of rubberized fabric and reinforcing steel rings. The body is sealed with flanges. One of the flanges is provided with an air-intake branch. The flanges must be coaxial and are designed to be attached both to the fixed and the resilient-mounted parts of the vehicle or device.
