Rack and Pinion Hydraulic Rotary Actuators

The HR series hydraulic rotary actuators generate torque through a gear wheel and a rack driven by two hydraulic cylinders. This solution simplifies the kinematics and is easy to maintain. They are recommended whenever the angle and torque of a rotating component need to be controlled: positioning, tilting, handling, automation.
They are also available with magnetic pistons, for use with magnetic proximity sensors along the entire piston stroke.
Every actuator is individually tested to ISO 10100 before delivery. Italian manufacturing and 50 years of experience in the industry guarantee high quality standards for industrial automation applications.
