About the Airtac SAI125 Standard Air Cylinder SAI125AX160
The AirTAC SAI125X160 is a double-acting ISO 15552 profile cylinder offering a robust 6136 N push force at 0.5 MPa and 8590 N at 0.7 MPa. Its 160 mm stroke handles substantial actuation tasks in heavy-duty machinery. Because it uses an extruded aluminum barrel, it avoids tie-rod design while maintaining strict ISO 15552 mounting interchangeability.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or mildly chemical washdown environments. It utilizes PT tapered port threads, and because no magnet is specified, it does not include sensor tracks out of the box.

Where the Airtac SAI125 Standard Air Cylinder SAI125AX160 Is Used
Heavy Machinery Forming
Provides the high thrust needed for metal bending and forming presses, utilizing the 6136 N push force at 0.5 MPa to shape heavy workpieces.
Pallet Handling Stops
Acts as a robust stopper mechanism on high-mass pallet conveyors, where the SUS420J2 rod material withstands repeated impact and environmental exposure.
Automated Clamping
Secures large cast components during CNC machining, relying on the stable ISO 15552 mounting interface to maintain rigidity under heavy cutting loads.
Is the Airtac SAI125 Standard Air Cylinder SAI125AX160 the Right Cylinder?
Choose this 125 mm bore when 80 mm falls short—the 80 mm variant only provides 2513 N at 0.5 MPa, whereas this model steps up to 6136 N. If your application requires position feedback, you must specify the -S magnet option to utilize CMSE or DMSE switches in the dual sensor grooves. For operations that must hold a load securely without continuous air pressure, this standard cylinder will drift; you should specify the SAIL locking variant or an external rod lock instead. It serves as a drop-in replacement for any ISO 15552 cylinder with a 125 mm bore, 160 mm stroke, PT G1/2 port, and standard mounting accessories like the CA clevis.
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 SAI125 Standard Air Cylinder SAI125AX160 FAQ
At 0.5 MPa it provides 6136 N of push force and 5734 N of pull force. If you increase the operating pressure to 0.7 MPa, the push force rises to 8590 N.
Yes, the SAI125X160 is dimensionally interchangeable with any ISO 15552 standard cylinder. You can drop it in as a replacement using the same mounting interface and G1/2 port location.
