OpTK

The Optimux OpTK rotary piston-cylinder actuator combines high torque and aerodynamic stiffness for excellent throttling capability. These features are designed to be a lightweight, robust and compact component.

The actuators and cylinders are designed for supply pressures up to 150 psi, enabling very high torques. The actuator uses a rocking piston to directly convert linear motion to rotary motion - thrust to torque. The oscillating piston assembly, combined with the spline shaft and lever, eliminates the loss of motion and gives the OpTK extraordinary precision and resolution.
