Air Bellows 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 provide 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
