The standard
in low-pressure hydraulic systems

The E1 rotary actuator is the latest rotary actuator in our product range. With regard to application, low-pressure hydraulic systems, with typical pressure ratings of 40, 60, 80 or 100 bar, are of relevance here.


The E1 functions according to the "helical gear" principle and, due to its compact design, only requires a minimum amount of space. The diverse options offer a maximum degree of flexibility and functionality. With the E1, Eckart offers you a high-performance series, allowing optimal adaptation to your particular requirements.

Because of its torque, angle of rotation, pressure range, positioning accuracy, stability of position, type of attachment and dimensions, the Eckart E1 rotary actuator can be used in a wide range of applications.

The selection ans 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.
