The AirTAC Airtac SC40 Standard Cylinder SC40X150SFB is a genuine double-acting standard air cylinder with a Ø40mm bore and 150mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X150SFB is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa. With a 40 mm bore and 150 mm stroke, it uses a 16 mm diameter piston rod with M12x1.25 threads, making it a robust actuator for medium-duty linear tasks.
This model is configured with a built-in magnet (-S) for direct mounting of CMSG/DMSG/EMSG sensors, and an FB rear rectangular flange (F-SC40FB) for secure end-face mounting. The standard TPU seals provide reliable operation from -20 to +70 °C, and the PT1/4 port supplies ample flow for speeds up to 800 mm/s.

The 150 mm stroke and 628 N push force are ideal for raising and lowering part stops on light-duty conveyors, where the rear flange mount saves space.
Use the built-in magnet sensors to confirm clamp position. The 16 mm rod provides good rigidity for pressing workpieces against a fixture at up to 1130 N.
The FB rear flange allows direct mounting to a frame to slide a small interlock guard or safety door open and closed with sensor feedback.
Choose the SC40 when your application needs between 528 N (pull) and 628 N (push) at 0.5 MPa. If you require more force, stepping up to the SC50 bore provides 982 N push at the same pressure. For a 150 mm stroke, the 40 mm bore is well within its 1200 mm maximum standard stroke limit, ensuring stable rod support.
To guarantee a correct replacement, match five key points: bore (40 mm), stroke (150 mm), port thread (PT1/4), mounting accessory (FB rear flange), and the magnet option (-S). This model's rear flange allows for rigid mounting against a machine bulkhead, keeping the cylinder body stable during actuation.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force is 528 N. At the maximum operating pressure of 0.9 MPa, the push force increases to 1130 N.
Yes. The '-S' suffix in the model code SC40X150SFB indicates a built-in magnet is installed on the piston. This allows you to clamp AirTAC CMSG, DMSG, or EMSG reed and solid-state sensors directly onto the cylinder barrel for position detection.
