The AirTAC SC40 Standard Cylinder SC40X240S is a genuine double-acting standard air cylinder with a Ø40mm bore and 240mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The SC40X240S is a double-acting single-rod pneumatic cylinder from the AirTAC SC tie-rod series, delivering 628 N of push force and 528 N of pull force when operated at 0.5 MPa. Its 240 mm stroke suits medium-reach clamping, pressing, and material-transfer tasks, and the 16 mm diameter piston rod provides good rigidity for axial loads.
The built-in magnet (-S suffix) allows CMSG, DMSG, or EMSG reed and solid-state sensors to mount directly onto the barrel for non-contact position sensing. With a body length A of 142 mm and a 21 mm adjustable air cushion at each end, this cylinder decelerates the piston smoothly to reduce end-of-stroke impact.

Moves components between conveyor lanes or indexing stations with a 240 mm reach, using the built-in magnet for end-of-stroke confirmation.
Delivers 628 N of clamping force at 0.5 MPa for gluing, welding, or assembly fixtures, with sensor feedback to ensure the clamp is fully engaged.
Actuates diverter gates on packaging lines, where the magnet-equipped barrel simplifies mounting of position sensors for gate-open and gate-closed signals.
Choose the SC40 bore for force requirements around 628 N at 0.5 MPa. If your load demands more force, step up to the SC50, which provides 982 N push at the same pressure. For lighter, faster applications, the SC32 delivers 402 N. When replacing an existing cylinder, match five points: 40 mm bore, 240 mm stroke, PT port thread, the built-in magnet (-S), and the basic mounting style.
At 240 mm stroke, the rod is well-supported for axial loads, but any side force should be managed with an external linear guide to protect the rod bearing and piston seals from premature wear.
Quick checklist
At 0.5 MPa, the cylinder produces 628 N extending and 528 N retracting. At the maximum operating pressure of 0.9 MPa, the extending force reaches 1130 N.
Yes. The -S suffix designates a built-in magnet in the piston, making the SC40X240S compatible with AirTAC CMSG, DMSG, and EMSG sensors that clamp onto the barrel's external tie-rod grooves.
