rotary actuator
The PSM2 is a pneumatic rotary actuaor that works according to the principle of the dual curve-roller deflection, and is most suited to applications in small installation spaces and with low weight requirements.

High-quality aluminium alloys and modified plastics are used as materials. As a result of this material combination, the rotary actuator has an extremely low weight. The sizes/operating widths vary, with diameters ranging from 40 mm to 100 mm, and a torque of up to 80 Nm at an operating pressure of 6 bar can be achieved. The maximum operating pressure is 10 bar.
Due to the design of the standard drive shaft with a key hub, it is possible to insert a so-called thread adaptor or a hub adaptor, depending on requirements, which can then be equipped with all manner of connecting profiles, such as gear-shaft, rectangular, hexagonal, cylindrical and polygonal profiles.
Because of its torque, angle of rotation, pressure range, positioning accuracy, stability of position, type of attachment and dimensions, the Eckart PSM2 rotary actuator can be used in a wide range of applications.
The selection and the size depends above all on the demands and the operating conditions under which the rotary actuator is operating. For the planning of special items, it is also important for us to be aware of all technical details.
