The reference
among the rotary actuators

The SM4 is a rotary actuator with an operating pressure up to 250 bar, which works according to the 'helical gear' principle.  How often have you searched for a rotary unit capable of executing a rotary movement or a limited rotational movement in an extremely small installation space? Frequently? If so, then Eckart can offer the perfect solution with its current 250-bar rotary actuator, the small and compact SM4.
