The AirTAC Airtac SC40 Standard Cylinder SC40X150SFA 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 SC40X150SFA is a double-acting pneumatic cylinder delivering 628 N of push force at 0.5 MPa and up to 1130 N at 0.9 MPa operating pressure. With a 40 mm bore and 150 mm stroke, it uses a 16 mm diameter piston rod with M12x1.25 male threads and PT1/4 port connections, providing a compact yet robust actuation solution.
This model includes a built-in magnet (-S suffix) for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors, enabling precise end-of-stroke detection. The FA front rectangular flange (F-SC40FA) allows rigid panel mounting on the rod side, while the standard TPU seals ensure reliable operation from -20 to +70 °C.

The 628 N push force at 0.5 MPa easily operates diverter gates and stops on light-to-medium-duty conveyor lines, with the front flange enabling secure end-face mounting.
Ideal for pneumatic clamping in CNC or assembly jigs where the 150 mm stroke provides ample clearance for part loading, and the magnetic piston confirms clamp position via sensors.
Delivers consistent force for pressing, labeling, or carton sealing in packaging machinery, with the front flange simplifying integration into the machine frame.
For applications needing more force, consider stepping up to the 50 mm bore SC50 series, which provides 982 N at 0.5 MPa. If lower force and a lighter actuator are acceptable, the 32 mm bore SC32 series offers 402 N. The 150 mm stroke is well within the 1200 mm maximum standard stroke for this bore.
To ensure a direct replacement, match these five points: 40 mm bore, 150 mm stroke, PT1/4 port thread, FA front flange mounting (F-SC40FA), and the -S magnet for sensor compatibility. The SC is a tie-rod cylinder and is not dimensionally interchangeable with ISO 15552 profile cylinders.
Quick checklist
At 0.5 MPa, the theoretical 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. The theoretical maximum force at 1.0 MPa is 128 kgf.
No. The AirTAC SC series is a tie-rod cylinder with a shorter body length (142 mm body for the 40 bore) and is not dimensionally interchangeable with ISO 15552 profile cylinders. It should only replace another AirTAC SC tie-rod cylinder matching the same bore, stroke, port, mounting, and magnet configuration.
