Festo piston rod cylinders are pneumatic drives for executing linear movements. Whether as round cylinder, profile cylinder, compact cylinder, short-stroke cylinder, flat cylinder, miniature cylinder, screw-in or stainless-steel cylinder: depending on the piston diameter, thrust forces of up to 50 kN at 6 bar are possible. Selected types in accordance with the ATEX directive are additionally suitable for explosive atmospheres or are made of corrosion-resistant stainless steel and therefore particularly easy to clean.

Thanks to their round design, round cylinders can even be installed in tight spaces. What all round cylinders have in common is excellent operational performance, a long service life, and quick and easy installation. The piston rod cylinders are available both as double-acting and single-acting actuators, as well as pneumatic cylinders according to standard ISO 6432.
Profile cylinders and tie rod cylinders have identical mounting interfaces and the same technical data, and both have dimensions that conform to the ISO 15552 standard. However, these linear drives differ above all in how the proximity switches are mounted: they are securely inserted in the slot on the profile tube, while on cylinders with tie rods the proximity switches are attached to a tie rod using a separate mounting kit.
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. Short-stroke cylinders start from a stroke of 2.5 mm and flat cylinders are characterized – as the name suggests – by a particularly flat design with an anti-rotation oval piston.
Multimount cylinders are cylinders that can be mounted from one or more sides without additional mounting attachments (except for screws). Cartridge cylinders can be installed and operated in a single-acting way in a threaded hole directly in the system. Separate accessories for mounting these piston rod cylinders and connecting the air supply are not required. This enables an extremely space-saving arrangement.
These are piston rod cylinders with an additional clamping unit for clamping the piston rod. Clamping is frictional when the operating pressure falls below a minimum value and – depending on the type – can be with or without backlash. Cylinders with a clamping mechanism are used for static holding. A holding brake with a relevant test certificate is required for dynamic braking and use in safety-related controllers.
