CONTITECH air actuators resist contamination that damages traditional metal pneumatic and hydraulic cylinders.
ContiTech says air actuators eliminate the need for dynamic seals that are essential in traditional cylinders. This means there is no path for external contamination to enter the air actuator. It eliminates breakaway (stick-slip) friction that can plague cylinders in low-load or low-speed conditions, so the actuators respond immediately and uniformly even to small pressure variations.
The ContiTech line ranges from 51mm to 1016mm in diameter. With a maximum working pressure of 115psi, the actuators generate compression forces or support loads to 30,400kg. Designs with reinforced internal materials handle pressures to 175psi.
Air actuators are used instead of pneumatic or hydraulic cylinders in applications such as material-handling equipment, agricultural machinery, food processing, paper and textile equipment, punch and forming presses, and sawmill machinery.
They are especially suited for applications with adverse ambient conditions and high force requirements. Typical examples include low-temperature (-60°C) wood-processing applications or high-temperature glass and paper manufacturing with sustained temperatures of 115°C and peak temperatures reaching 130°C.
