Our Products
All PTM-actuators are based on the rack and pinion principle. This fact is responsible for small dimensions. For different mounting alternatives all PTM actuators can be mounted on three or four mounting surfaces. Rotation angles more than 185 are available. Our progressive working end position damping starts working just about 10 before reaching the end position by throttling the exhaust air automatically. This guarantees reaching the exact end position. This excludes bouncing in the end position even during air pressure variation .A technically necessary backlash of 0, 5 is unavoidable at Mini-Actuators with rack-and pinion principle.
Main characteristics of our actuators are small dimensions, low weight and long lifetime. The power transmission is placed in the centreline of the rack piston to guarantee a very long lifetime. There are PTM-actuators which were returned for repair only after 13 years of continuous running. The smallest Pneumatic Mini Actuator DA 0020 with rotation angle of 95 and a torque of 20 Ncm, has the dimensions of only 20x20x43 mm and a weight of 0, 050 kg.

The accelerated mass represents a major problem in pneumatics. The actuator may be self-destruct because of the kinetic energy. Some clients had this unpleasant experience already. Throttle valves can be used to control the rotating speed. For damping of the accelerated mass before reaching the endpositions it is possible to install hydraulic shock absorbers. This will improve the situation, but the result is not totally satisfactory. We developed the Hydraulic-Pneumatic RotaryActuator -HPA to solve this problem. We split the task into two steps: The cheap, clean and compressible medium air will continue to do the work for the actuation. But to control the moving mass the non compressible medium oil is used in a closed hydraulic system. This allows to adjust the rotation speed exactly.A restart after an E-stop is possible without any problems. There are two independent and adjustable rotation speeds possible. This guarantees a precise and constant adjustment of the end position damping.This makes our hydropneumatic drives unique in the world.
