The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X480STC is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 480mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI40X480-S is a double-acting ISO 15552 profile cylinder engineered for applications requiring a 480 mm stroke and reliable magnetic position sensing. Operating at 0.5 MPa, it generates 628 N of push force and 528 N of pull force. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standard ISO 15552 mounting footprints.
Equipped with a factory-installed magnet (-S), this unit seamlessly integrates with CMSE and DMSE sensor switches fitted into the dual side grooves. The piston rod utilizes standard carbon steel for high tensile strength, while the adjustable air cushions at both ends absorb impact energy at stroke completion.

Actuates diverter arms on packaging lines, utilizing the 480 mm stroke to push products smoothly between parallel conveyor belts.
Lifts lightweight totes or trays to secondary processing tiers, relying on the 628 N push force and TC trunnion mounting for smooth pivot action.
Drives horizontal sorting gates to route machined components by size, using CMSE sensors to confirm full extension before indexing.
Selecting this 40 mm bore over the smaller 32 mm variant upgrades your push force from 402 N to 628 N at 0.5 MPa without significantly increasing the physical footprint. Conversely, if your application demands the 982 N output of the 50 mm bore, stepping up is recommended. This 480 mm stroke falls within the standard maximum of 1200 mm for this bore.
Because the stroke exceeds 300 mm, the extended rod is susceptible to bending under side loads. Utilize an external guide rail or a guided cylinder carriage to prevent rod-bearing damage. For tasks requiring load holding during air loss or valve centering, note that the standard adjustable air cushion only decelerates the piston and does not lock it; an external pilot-operated check valve or the SAIL lock variant is necessary for position holding. This model features a PT tapered port thread, a TC trunnion mount, and operates at speeds of 30-800 mm/s.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI40X480-S provides a push force of 628 N and a pull force of 528 N. If operated at 0.7 MPa, the push force increases to 879 N.
Yes, the SAI40X480-S is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting setups, matching the 40 mm bore, 480 mm stroke, and TC trunnion interface without altering the machine frame.
