Compact cylinders, short-stroke cylinders and flat cylinders are pneumatic piston rod cylinders that are united by one great advantage: their compact design makes the power packs usable for a wide range of applications even in confined spaces. Compact cylinders are pneumatic cylinders with an installation length that is extremely compact in relation to the stroke length. Compact cylinders are typically used when space is extremely limited and the requirements on lateral loads are low. The compact cylinders belong to the group of direct mounting cylinders and are usually installed without any specific mounting accessories.
