ContiTech air actuators and air isolators are unparalleled for reliable performance in harsh applications. With a broad product range of C, D, R, S and RL model series and custom engineered components, they master even difficult pneumatic automation tasks in machine and plant engineering. In comparison to pneumatic or hydraulic cylinders, ContiTech air actuators contain no piston rod, allowing for compact designs, angular movement and robust performance in challenging applications. They can be filled with compressed air, nitrogen, water or hydraulic oil, in environments ranging from -76 ˚F (-60 ˚C) to 266 ˚F (130 ˚C). ContiTech air spring systems are renowned for their maintenance-free, long service life and high quality; Long service life, maintenance-free operation in extreme temperatures and the harshest environments High operational safety, reliability and quality offer low operating costs and increased profits Imperial and Metric dimensions, with 3 rubber compounds across 5 model series Frictionless rodless actuator or low frequency air isolator, with angular movement and lateral misalignment capabilities. ContiTech Bellow, Series: C Series, 233 mm Stroke Length, 21.8 KN Maximum Force, Double Cylinder Action, G3/4 Port, 8 bar Pressure
