AIRON CD series giant compact cylinders, available with bores of 125, 160 and 200 mm, allow exertion of high thrust with considerably lower longitudinal dimensions than those on ISO 6431 VDMA 24562 cylinders. Double-acting, equipped with elastic shock absorbers; available in standard and through rod versions, with or without a magnetic ring. The heads have four threaded holes with centre-to-centre distance identical to that on ISO 6431 cylinders, thus allowing use of the same accessories and optimising use of relative stocks. Moreover, it is also possible to fix the cylinder directly to a wall (on which 4 threaded holes have been made) using just 4 screws (fig. 1). Each version offers several variants, such as seals suitable for temperatures as high as 150° C, tandem units to provide greater thrust and multi-stage units to execute multiple positions, with the rod ends having a male thread etc. so that the technician can choose a cylinder with the most suitable characteristics for the application in hand.
