FLUID POWER PRODUCT FOCUS
As single-acting pneumatic cylinders, the ContiTech air actuators are used in machine and plant engineering— wherever force is generated for lifting and pressing.
AIR ACTUATORS Win Over Users with Durability and Long Service Life BY CONTITECH
T
he air actuators are single-acting pneumatic cylinders, and are used in machine and plant engineering. Thanks to their robust and simple design, they offer unique advantages over conventional pneumatic cylinders in many application fields. They are used primarily where extreme force has to be generated and adverse ambient conditions prevail. In addition to the standard range, there are also special material designs available as catalog items for particular applications. For instance, there are air actuators that are heat resistant for

temperatures up to 257°F (high-temperature versions) or cold resistant down to -75°F (low-temperature versions). ECO air actuators are used in the case of aggressive media in the paper-producing and chemical industries.
A SIMPLE DESIGN FULL OF ADVANTAGES Air actuators can withstand high dynamic loads. The materials used have been optimally tried and tested in the production of commercial and passenger vehicles, as well as rolling stock. The dimensionally stable elements in
their design are compatible to that of a tire or an air spring. This simple construction allows for complete solutions that are cost effective. The rodless construction functions without parts or seals moving against each other. This prevents any stick-slip effect, thus eliminating static friction. The actuators respond immediately and uniformly, even to small variations in pressure. In pneumatic applications, they can be operated using either oil-free or lubricated compressed air. Depending on the product type, the air actuators can be used for tilt angles up to 30°. This characteristic enables the designer to avoid costly con-
