Operation
Due to their flexible construction the mounting of air bellows is less critical than conventional pneumatic cylinders,which normally require rigid fixing and guidance and provide only axis location of the end plates may be off set by up to 10mm.
When pressurised air bellow will follow the line of leased resistance.Accordingly care must be taken with mounting geometry in angled applications.
When depressurised air bellows will fit in to surprisingly small spaces,especially useful for clamping or moving awkwardly shaped or very heavy loads.
In operation it is recommended that the unit is not allowed to "bottom out" or achieve its maximum height.Various mechanical devices may be employed to achieve this.
