The AirTAC Airtac SC40 Standard Cylinder SC40X1200S is a genuine double-acting standard air cylinder with a Ø40mm bore and 1200mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X1200S is a double-acting single-rod tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). With a 40 mm bore and a 16 mm diameter piston rod, this model uses the maximum standard stroke of 1200 mm, making it suitable for long linear movements in material handling or gate actuation.
The built-in magnet (denoted by the -S suffix) allows direct mounting of CMSG, DMSG, or EMSG reed and solid-state sensors along the barrel for precise end-of-stroke or mid-stroke position feedback. Its adjustable pneumatic cushion (21 mm) decelerates the piston smoothly, reducing end-cap impact noise.

The 1200 mm stroke and built-in sensor magnet make this cylinder ideal for actuating diverter gates on wide conveyor systems, with magnetic sensors confirming open/closed positions.
Delivers 628 N of push force to slide large panels or sheets between workstations. The adjustable cushion ensures a gentle stop, preventing damage to lightweight materials.
Provides the long, straight-line motion needed to lift or slide industrial doors, with the TPU seals performing reliably in standard -20 to +70°C warehouse environments.
Choose the SC40 bore for applications needing up to 628 N at standard plant pressure. If your load requires more force, step up to the SC50 bore, which provides 982 N at 0.5 MPa. For a smaller, lighter assembly, the SC32 bore offers 402 N. At a 1200 mm stroke, the piston rod is fully supported at both ends, but avoid direct side loading on the rod end; for guided motion, pair this cylinder with an external linear guide or consider a guided cylinder assembly. To replace an existing unit, match the 40 mm bore, 1200 mm stroke, PT1/4 port thread, basic mounting, and ensure the replacement has the -S magnet option for sensor compatibility.
Quick checklist
At the standard operating pressure of 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 increases to 1130 N. The theoretical maximum force at 1.0 MPa is 128 kgf.
Yes. The -S suffix in the model code SC40X1200S indicates a built-in magnet on the piston. This allows you to clamp compatible AirTAC CMSG, DMSG, or EMSG sensors directly onto the tie-rod barrel to detect piston position without additional brackets.
