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, (580.152, 870.228, 1160.304, or 1450.380 psi) 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.
