The AirTAC Airtac SC40 Standard Cylinder SC40X270S is a genuine double-acting standard air cylinder with a Ø40mm bore and 270mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X270S is a double-acting single-rod pneumatic cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and 270 mm stroke, it uses a 16 mm diameter piston rod with M12x1.25 threads, making it a robust choice for medium-duty linear tasks.
This model includes a built-in magnet (-S suffix), allowing CMSG, DMSG, or EMSG reed and solid-state sensors to be mounted directly on the tie-rod barrel for precise end-of-stroke or mid-stroke position sensing. The adjustable air cushion at each end decelerates the piston smoothly, and the standard PT1/4 port threads ensure straightforward pneumatic connections.

The integrated magnet allows sensors to confirm gate position, making this cylinder ideal for diverting packages on conveyor lines where mid-stroke sensing is required.
Delivers 1130 N of clamping force at 0.9 MPa. The 16 mm rod provides good rigidity for pressing components into fixtures or holding parts during machining.
With a 270 mm stroke, it's suited for pusher or lift mechanisms in material handling. The adjustable cushion protects the end caps during high-cycle operation.
The SC40X270S suits applications needing 270 mm of travel with sensor feedback. If your force requirements increase, stepping up to the 50 mm bore provides 982 N at 0.5 MPa. For strokes over 300 mm on this 16 mm rod, consider an external guide or a guided cylinder to prevent rod bearing wear from side loads. When replacing, match the 40 mm bore, 270 mm stroke, PT1/4 ports, the built-in magnet, and the basic mounting style to ensure a drop-in fit.
Quick checklist
At the standard 0.5 MPa operating pressure, the push force is 628 N and the pull force is 528 N. If operated at the maximum 0.9 MPa, the push force increases to 1130 N.
Yes, the -S suffix indicates a built-in magnet around the piston. This allows AirTAC CMSG, DMSG, or EMSG sensors to be clamped directly onto the barrel for contactless position detection.
