Bellows cylinder 9109

9109 and SP series air bellows are high thrust single acting actuators with one, two or three convolutions. In bores Ø70 to Ø660mm and strokes 20 to 375mm in standard and high temperature versions for vibration damper applications. The simplicity of construction provides an extremely long, virtually maintenance-free service life even under arduous conditions. 9109 and SP series air bellows are the ideal choice for applications requiring short stroke, high thrust single acting actuators. They incorporate no reciprocating metal parts and so provide virtually frictionless thrust compared with conventional pneumatic cylinders. 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 15° between faces. Additionally, the axial location of the end plates may be off set by up to 10 mm. When pressurised air bellows will follow the line of least resistance. Accordingly, care must be taken with the mounting geometry in angled applications. In operation it is recommended that the unit is not allowed to ""bottom out"" or achieve its maximum height and mechanical devices should be employed to prevent this. When depressurised air bellows will fit in to surprisingly small spaces, especially useful for clamping or moving awkwardly shaped or heavy loads and vibration applications i.e. device feeders at high frequency. The return stroke is provided in part by the natural spring action of the bellows but more usually by the load itself.
