About the Airtac SAI100 Standard Air Cylinder SAI100AX120
The AirTAC SAI100X120 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, 120mm stroke actuator is built to handle substantial pneumatic loads. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that simplifies mounting and sensor placement.
Configured here with an SUS420J2 stainless steel piston rod (material code A), it offers superior corrosion and wear resistance compared to standard carbon steel. Fluid ports feature PT tapered threads (G1/2). Because this unit lacks the -S magnet option, it is optimized for pure mechanical force transmission rather than electronic position sensing.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX120 Is Used
Heavy-Duty Stamping
Provides the 3927 N push force at 0.5 MPa required to form and stamp thick metal components in automated fabrication lines.
Injection Mold Ejection
Utilizes the 120mm stroke to positively eject heavy finished plastic parts from large injection molding machinery.
Pallet Lifting
Lifts and positions loaded pallets on packaging conveyors where high thrust and rigid structural support are mandatory.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX120 the Right Cylinder?
Select this 100mm bore actuator when your application requires significantly more power than a 63mm cylinder (which provides 1559 N at 0.5 MPa) but does not demand the massive footprint of a 125mm unit. The 120mm stroke is ideal for short, high-force clamping or lifting movements. For installations needing end-position feedback, you must specify the -S magnet option to utilize CMSE or DMSE switches in the dual sensor grooves.
This model is a dimensional drop-in replacement for other ISO 15552 cylinders, matching standard mounting accessories like FA flanges or TC trunnions. Remember that standard double-acting cylinders drift if air pressure is lost; if your workflow demands fail-safe load holding, consider the SAIL variant with an air-released lock or an external pilot check valve.
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.
Airtac SAI100 Standard Air Cylinder SAI100AX120 FAQ
At a 0.5 MPa operating pressure, 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 SAI100X120 is manufactured to the ISO 15552 standard, making its mounting dimensions and center distances fully interchangeable with equivalent ISO 15552 profile cylinders from other brands.
