Raagen Rotary Test Actuators

Raagen Rotary Test Actuators are heavy-duty torque generation devices that operate under precision servovalve control. When matched with servovalves, transducers, and closed-loop control electronics, Rotary Actuators are suited for testing materials, structures, and components.

The double-vane rotor design accommodates full force application through 100° of rotation. Matched reaction brackets, diaphragm flexures, and reaction bases allow you to create versatile test configurations that you can easily reconfigure. Available instrumentation options include angular displacement transducers, torque cells, and differential pressure cells.



» Heavy-duty bearings accommodate significant radial and axial loads

» Precision chamber and rotor design ensures zero actuator backlash during torque reversals

» Available with a complete line of fixturing and angular displacement transducer options

» Servovalve ports are compatible with standard servovalve manifolds

» Balanced double vane rotor design reduces friction and provides continuous torque output through 100° of rotation

» Separate actuator mounting and fixture attachment equipment accommodate diverse test articles and configurations

» Diaphragm flexures are available to reduce excessive thrust and side loads exerted on the test specimen
