Overview
The SMC CDRA1BW30-90-F79L is a rack & pinion rotary actuator from the CRA1 series, engineered for precise positioning and high torque output in compact form. This unit provides 90° rotation and is designed for both manual and automated pneumatic control applications. The F79L suffix indicates solenoid valve compatibility for automated switching. Available in used condition, this actuator is fully functional and suitable for retrofit, maintenance, or spare parts applications.
