The AirTAC Airtac SC40 Standard Cylinder SC40X263S is a genuine double-acting standard air cylinder with a Ø40mm bore and 263mm stroke, PT1/4 air ports and adjustable end cushioning. It is used for push, pull, lift and clamp motion in industrial automation.
The AirTAC SC40X263S is a double-acting tie-rod cylinder delivering 628 N of push force at 0.5 MPa (1130 N at 0.9 MPa). Its 16 mm diameter piston rod and 21 mm air cushion provide smooth deceleration over a non-standard 263 mm stroke, making it a workhorse 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 clamp directly onto the barrel for reliable end-of-stroke detection. The body length A is 142 mm, giving a total extended length of approximately 405 mm.

Actuates a diverter gate on a conveyor line, using the built-in magnet and DMSG sensors to confirm open/closed position for reliable product routing.
Provides 628 N of holding force for a woodworking or light metalworking jig, with sensor feedback ensuring the part is clamped before the machining cycle starts.
Pushes cartons onto a palletizing station. The 263 mm stroke clears the conveyor width, and the adjustable cushion protects the carton from impact damage.
Choose the SC40 when your application needs around 628 N at standard plant air. If you require more force, step up to the SC50 which provides 982 N at the same 0.5 MPa pressure. For a 263 mm stroke, ensure the rod is not subjected to side loads; long unsupported strokes on a 16 mm rod can bend under lateral force—consider an external guide or a guided cylinder if side loading is present.
For a direct replacement, match five points: 40 mm bore, 263 mm stroke, PT port thread, basic mount (no bracket), and the -S magnet for sensor compatibility. This is a genuine AirTAC SC tie-rod cylinder, not an ISO 15552 profile unit.
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, so AirTAC CMSG (reed) or DMSG/EMSG (solid-state) sensors can be clamped directly onto the barrel to detect piston position without any modification.
