The air springs consist of a flexible elastomer rubber body with
nylon fabric reinforcement, and rustproof plates with an air inlet
and mounting blind nuts. The rubber bellows can be used both as
vibration isolators and rubber actuators. The air springs absorb up
to 99% of the unwanted vibrations avoiding further damages to the
machines and metallic structures. At the same time, they reduce
noise level.
The rubber actuators have been developed to replace the traditional
air or hydraulic cylinders. Due to their design, the air pressure
inside the bellow produces an upward stroke, thrust, tension,
angular movements or fast anchoring movements.
