The AirTAC Airtac SC40 Standard Cylinder SC40X330S is a genuine double-acting standard air cylinder with a Ø40mm bore and 330mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X330S is a double-acting AirTAC SC tie-rod cylinder with a 40 mm bore and 330 mm stroke, factory-equipped with a built-in magnet for direct mounting of CMSG/DMSG/EMSG reed or solid-state sensors. At 0.5 MPa it delivers 628 N pushing force, making it a capable mid-bore actuator for automated handling and assembly tasks.
With a 16 mm piston rod, M12x1.25 rod thread, and PT1/4 ports, this cylinder provides a 21 mm adjustable air cushion at each end to decelerate the load smoothly. The body length A is 142 mm, giving a total extended length of approximately 472 mm. The standard TPU seals suit operating temperatures from -20 to +70 °C.

The 330 mm stroke moves components between conveyor lanes, while the built-in magnet and CMSG sensors confirm full extension and retraction for reliable interlocking.
628 N of force at 0.5 MPa presses bearings or bushings into housings. The adjustable cushion prevents impact damage to the workpiece at the end of the 330 mm travel.
Operates a divert gate or stop on a packaging line. Sensor feedback ensures the gate is fully open or closed, preventing product jams and protecting downstream equipment.
Choose the SC40X330S when your application needs a 40 mm bore with sensor feedback and a 330 mm stroke. For higher force at the same pressure, step up to the 50 mm bore (982 N at 0.5 MPa); for a lighter, more compact solution, the 32 mm bore (402 N at 0.5 MPa) may suffice. The built-in magnet lets you clamp position sensors directly onto the barrel without additional brackets.
At 330 mm stroke, the 16 mm rod is relatively long. If the load applies any side force, use an external guide or linear rail to protect the rod bearing from bending and premature seal wear. For direct replacement, match bore, stroke, PT port thread, the basic mounting style, and the -S magnet option to another AirTAC SC cylinder.
Quick checklist
At 0.5 MPa, 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 reaches 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix indicates a built-in magnet inside the piston. You can clamp compatible CMSG (reed) or DMSG/EMSG (solid-state) sensors directly onto the barrel to detect piston position without external brackets.
