Pneumatic actuators

In a pneumatic cylinder, compressed air is used to exert force on a cylinder piston and thus move it in a specific direction. The motion of the piston is transmitted to the parts to be moved via the piston rod or magnetic friction closure. A pneumatic cylinder is an actuator operated with compressed air usually up to a maximum of 12 bar to generate a linear or rotary motion. A distinction must be made between single-acting and double-acting cylinders (work is performed only in one direction or in both directions). Typical applications for pneumatic actuators are tensioning, lifting, countersinking, pushing, pulling, feeding, turning, gripping, clamping and holding, joining, stopping, stamping, embossing and others. Pneumatic actuators are characterized by high acceleration and deceleration. The achievable speeds range between 10 mm/s and up to 3 m/s. Pneumatic drives are robust and flexible due to the compressibility of the air.

Servo-pneumatic positioning systems

At Festo, servopneumatics stands for controlled pneumatic positioning technology. Servopneumatics is always a system. It always consists of a cylinder with a linear potentiometer, a proportional directional control valve and a positioning controller. With a servopneumatic system, a pneumatic cylinder can move to a preset target position in a position-controlled manner or generate a preset target force in a force-controlled manner.
Because air is a compressible drive medium, servopneumatics are the "soft" positioning technology. If the actuator is controlled in its position, it can be pushed away by a correspondingly large external force. The systems are particularly attractively priced when masses > 10 kg are moved.
As the global market leader in servopneumatic systems, Festo now presents the third generation of servopneumatic drive systems.
