About the Airtac SAI100 Standard Air Cylinder SAI100AX225
The AirTAC SAI100X225 is a double-acting ISO 15552 profile cylinder engineered for high-thrust tasks, delivering 3927N of push force at 0.5 MPa. Because the 225mm stroke is a non-standard made-to-order length, it provides a tailored motion span for specialized machinery. The extruded aluminum barrel omits tie-rods, presenting a clean exterior that matches standard ISO 15552 mounting dimensions exactly.
This specific unit is configured with an SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance over standard carbon steel. It features PT tapered port threads and lacks a standard magnet, meaning it is optimized for pure actuation rather than direct sensor mounting.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX225 Is Used
Heavy-Duty Stamping
Supplies the 3927N push force at 0.5 MPa needed to form and stamp thick metal components in automated fabrication cells.
Pallet Diversion
Executes robust 225mm strokes to push heavy loaded pallets onto secondary packaging lines without standard stroke limitations.
Plastic Mold Ejection
Uses the SUS420J2 stainless rod to safely eject molded parts in humid environments, resisting corrosion during high-force retraction.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX225 the Right Cylinder?
Providing 3927N at 0.5 MPa, this 100mm bore sits comfortably above the 80mm class (2513N) and below the 125mm class (6136N). Choose this model when intermediate high-force output is required without stepping up to the larger 125mm footprint. Since the 225mm stroke is non-standard, ensure your machine design accommodates this exact length.
For this 225mm stroke length, side-load management is a critical design consideration. An unsupported piston rod of this length can bend under lateral stress, so utilizing an external guide rail or a fully guided cylinder is strongly recommended. Additionally, if the application requires the load to be held in place during a complete loss of air pressure, the standard SAI will drift; you must integrate an external pilot-operated check valve or specify the SAIL lock variant.
Quick checklist
- ✓ 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.
