Rubber Air Bellow Spring For Industrial

Air Bellow Spring are the ideal choice for applications requiring short stroke, high thrust single acting actuators.
Manufactured from fabric reinforced synthetic rubber in one, two or three convolutions according to stroke and model. They incorporate no reciprocating metal parts and so pro wide virtually frictionless thrust compared with conventional pneumatic cylinders.
All models are single acting only. The return stroke is provided in part by the natural spring action of the bellows but more usually by the load itself. The simplicity of construction provides an extremely long, virtually maintenance-free service life even under arduous conditions.
Air bellows are suitable for vibration applications i.e. device feeders at high frequency.
Operation of airspring
Due to their flexible construction the mounting of Air Bellows is less critical than with conventional pneumatic cylinders, which normally require rigid fixing and guidance and provide only one axis within a limit of 15degree between faces. Additionally the axial location of the end plates may be off set by up to 10 mm
