The AirTAC SAI40 Standard Air Cylinder SAI40AX225 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø40mm bore and 225mm stroke, G1/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI40X225 is a double-acting ISO 15552 profile cylinder offering a practical linear motion solution. It provides 628 N push force and 528 N pull force at 0.5 MPa, making it well-suited for medium-duty handling tasks. The 225 mm stroke gives extended travel for packaging and sorting equipment.
This variant features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches if a magnet is added later. Threaded PT ports and adjustable air cushions at both ends ensure quiet and controlled end-of-stroke deceleration.

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.
Provides the 628 N push force and 225 mm travel needed to extend and retract sealing jaws on automated flow-wrapping machines.
Drives linear diverters to push products of varying weights off high-speed conveyor belts with reliable double-acting power.
Handles the vertical lifting and horizontal transfer of medium-weight component trays between adjacent workstations.
If your application requires less force, stepping down to the SAI32 bore provides 402 N push force at 0.5 MPa, while moving up to the SAI50 bore yields 982 N. Because the 225 mm stroke exceeds 300 mm is not the case here, but at longer lengths you must manage side loading; for this 225 mm stroke, ensure adequate rod bearing support to prevent bending under lateral loads. The adjustable cushions help absorb kinetic energy at the stroke ends. Remember that a standard SAI cylinder does not hold its load when air pressure is removed; for position holding without live pressure, consider the SAIL locking variant or an external pilot check valve. This model serves as a dimensionally interchangeable direct replacement for other ISO 15552 profile cylinders, utilizing a G1/4 port, M12x1.25 rod thread, and compatibility with FA/FB flanges or LB foot mounts.
Quick checklist
At 0.5 MPa operating pressure, the SAI40X225 generates 628 N of push force and 528 N of pull force. At the maximum 1.0 MPa pressure, it can deliver up to 128 kgf of theoretical force.
Yes, the SAI40X225 is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders, featuring a standardized mounting interface, G1/4 PT ports, and an M12x1.25 rod thread.
