The AirTAC SC40 Standard Cylinder SC40X240 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 SC40X240 is a double-acting pneumatic cylinder from the AirTAC SC tie-rod series, delivering a push force of 628 N at 0.5 MPa and up to 1130 N at the maximum operating pressure of 0.9 MPa. With a 40 mm bore and a 240 mm stroke, this model uses a 16 mm diameter piston rod and features an adjustable air cushion of 21 mm at each end to decelerate the piston smoothly.
This cylinder has a compact body length A of just 142 mm, making it shorter than a typical ISO 15552 cylinder of the same bore. It is equipped with standard PT1/4 ports and TPU seals for a working temperature range of -20 to +70 °C. The basic configuration provides a robust, no-frills actuator ready for straightforward linear push-pull tasks.

The 628 N push force at 0.5 MPa is ideal for diverting light packages or components on a conveyor line, with the 240 mm stroke providing ample reach across a belt.
Use the SC40X240 for work-holding in CNC or assembly jigs. Its adjustable cushioning prevents impact shock that could disturb a precisely located part.
Apply consistent pressure for case sealing or label application. The double-acting cylinder provides controlled force in both directions for a clean, repeatable cycle.
Select the SC40 bore for applications needing between 400 and 600 N of force at typical plant pressures. If your load requires more force, stepping up to the SC50 bore provides 982 N of push force at 0.5 MPa. For a lighter, more compact solution, the SC32 bore delivers 402 N.
At a 240 mm stroke, the 16 mm rod is well-supported for axial loads, but avoid significant side loading without an external guide. For a direct replacement, match five key points: the 40 mm bore, 240 mm stroke, PT1/4 port thread, basic (no) mounting, and the absence of a magnet. This ensures dimensional and performance interchangeability with an existing AirTAC SC40X240.
Quick checklist
The theoretical push force on the piston rod extension is 628 N at 0.5 MPa air pressure, 879 N at 0.7 MPa, and reaches 1130 N at the maximum operating pressure of 0.9 MPa. The pull force on retraction is 528 N at 0.5 MPa.
No. The AirTAC SC series is a tie-rod cylinder that is physically shorter than an ISO 15552 profile cylinder. It is not dimensionally interchangeable with ISO 15552 mounts. It is a direct replacement only for another AirTAC SC40 cylinder with the same stroke, port, and mounting configuration.
