The AirTAC Airtac SAI40 Standard Air Cylinder SAI40X80S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 80mm 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 SAI40X80-S is a double-acting ISO 15552 profile cylinder with a 40mm bore and 80mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a magnet for proximity sensing (-S) and uses standard carbon steel piston rod material. It features PT tapered port threads and integrated sensor grooves on both sides of the barrel, allowing direct mounting of CMSE or DMSE series switches for precise position verification.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Ideal for diverting medium-weight packages on conveyor lines where 628N of push force and 80mm travel reliably actuates routing gates.
Provides stable holding force for machining or assembly fixtures, using the integrated magnet and sensors to confirm clamp engagement.
Suitable for lifting or pushing pallets and bins in automated storage systems where a compact 40mm ISO 15552 footprint is required.
Select this 40mm bore model when your application requires around 628N of push force at 0.5 MPa; step down to a 32mm bore (402N) for lighter loads or up to a 50mm bore (982N) if you need greater thrust. To match this cylinder for an ISO 15552 replacement, specify the 40mm bore, 80mm stroke, G1/4 PT ports, and the required mounting accessory (such as LB foot or FA flange). Include the -S suffix to ensure magnet compatibility with your chosen sensors.
Because the stroke is 80mm, side-load stress on the rod bearing is minimal, but always ensure the load is axially aligned to prevent premature seal wear. Note that this standard cylinder relies on adjustable air cushions to decelerate the piston at stroke ends; it does not hold position when air pressure is removed. For applications requiring dead-stop holding under pressure loss, consider the SAIL lock variant or an external pilot-operated check valve.
Quick checklist
At a standard 0.5 MPa operating pressure, the SAI40X80-S delivers a theoretical push force of 628N and a pull force of 528N. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X80-S is a genuine AirTAC profile cylinder built to ISO 15552 dimensional standards. It serves as a drop-in replacement for other ISO 15552 cylinders with matching 40mm bore, 80mm stroke, and G1/4 port specifications.
