The air spring used in the paper making machine press part / size press / calender
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.
