Rotary actuators generate a torqe through a cogwheel and a rack moved by a hydraulic cylinder.
This solution simplifies the kinematic and maintenance required during its life cycle. Rotary actuators have adjustable cushioning, this can generate a cushioning torque comparable to the maximum torque of the cylinder. The stroke end adjuster allows phasing the system with a regulation range of +/- 5 degrees.
Actuators are also available with a magnetic piston "mr series" which can be fitted with proximity switches along the stroke.
