Overview
The Numatics S2AK-03A9C-AAAA is a double-acting, single-rod tie-rod pneumatic cylinder actuator engineered for demanding industrial pneumatic control systems. This NFPA interchangeable Series A cylinder combines proven construction with reliable performance in manufacturing, automation, and material handling applications. With a 1-1/2″ bore and 3″ stroke, the S2AK-03A9C-AAAA delivers consistent force output and precise positioning.
Key Features
- Double-acting design — pressurized extend and retract for full directional control
