The Trimteck OpTK Rotary Piston-Cylinder Actuator combines high torque and pneumatic stiffness with excellent throttling capabilities. These characteristics are designed into a lightweight, rugged and compact assembly.
The actuator and cylinder are designed for supply pressures up to 150 psi, enabling very high torques. The actuator uses a rocking piston for direct conversion of linear motion to rotary motion – thrust to torque. The rocking piston assembly combined with a splined shaft and lever eliminates lost motion giving the OpTK extraordinary precision and resolution.
