About the Airtac SAI100 Standard Air Cylinder SAI100AX250
The AirTAC SAI100X250 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 3927 N of push force at 0.5 MPa, this 100mm bore unit is built to drive demanding loads across a 250mm stroke. Its extruded aluminum barrel omits traditional tie rods, presenting a clean profile that drops directly into standardized ISO 15552 mounting interfaces.
This specific configuration is equipped with a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and surface hardness. It utilizes PT tapered port threads, and because it lacks the -S magnet suffix, it is optimized for pure actuation rather than position sensing. Adjustable air cushions at both ends absorb kinetic energy at stroke endpoints.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX250 Is Used
Heavy-Duty Stamping
Provides the high thrust required for pressing bearings, bushings, or plates securely into heavy housings without mechanical play.
Pallet Diversion
Actuates large-scale routing gates and heavy diverter arms on packaging lines, smoothly moving fully loaded pallets.
Plastic Mold Ejection
Drives robust ejection mechanisms in injection molding setups, reliably clearing large formed parts from heavy tooling.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX250 the Right Cylinder?
Select this 100mm bore when a 80mm cylinder (providing 2513 N at 0.5 MPa) lacks the necessary thrust for high-friction environments, but stepping up to a 125mm bore would be physically oversized. The 250mm stroke is well within the 1500mm maximum standard limit for this bore, keeping the unit readily available. If your mechanism must hold a load vertically or resist drift when air pressure is removed, remember that standard pneumatic cushions only decelerate motion; you will need to specify the SAIL variant with an air-released lock or integrate an external rod lock.
For ISO 15552 drop-in replacements, verify that your existing mounting footprint matches standard FA/FB flanges or TC trunnions. Ensure your pneumatic infrastructure supplies PT-threaded fittings to match the G1/2 ports, and confirm that the 30-800 mm/s speed range aligns with your cycle time requirements.

- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI100 Standard Air Cylinder SAI100AX250 FAQ
At a standard operating pressure of 0.5 MPa, this 100mm bore cylinder generates 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
Yes, the SAI100X250 is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions and G1/2 port locations make it dimensionally interchangeable with other ISO 15552 cylinders, allowing for seamless retrofits.
