About the Airtac SAI40 Standard Air Cylinder SAI40AX130
The AirTAC SAI40X130 is a double-acting ISO 15552 profile cylinder offering a 40mm bore and 130mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it a robust choice for medium-duty automation tasks.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. It uses PT tapered port threads and lacks a standard magnet, meaning position detection requires external sensors rather than integrated groove switches.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX130 Is Used
Component Ejection
Ideal for pushing machined parts out of an automated lathe or mill, utilizing the 130mm stroke and 628N force to reliably clear the work area.
Package Diverting
Provides rapid actuation for conveyor belt sorting arms, using its 30-800 mm/s speed range to redirect lightweight cartons efficiently.
Clamping Fixtures
Suitable for holding workpieces in welding or machining fixtures, where the SUS420J2 rod material resists moisture and coolant spray.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX130 the Right Cylinder?
Selecting this 40mm bore provides a balanced output of 628N at 0.5 MPa, sitting neatly between the lighter 32mm bore (402N) and the heavier 50mm bore (982N). The 130mm stroke is ideal for compact ejection or clamping tasks where space is limited but a solid reach is required.
Because this standard actuator relies on air pressure for movement, it will not maintain a locked position if supply pressure drops or the valve centers. For applications requiring fail-safe load holding, consider the SAIL variant with an air-released lock or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it serves as a direct replacement for any standard 40mm bore actuator matching these mounting dimensions.
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 SAI40 Standard Air Cylinder SAI40AX130 FAQ
At a standard operating pressure of 0.5 MPa, the SAI40X130 generates 628N of push force and 528N of pull force. At 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X130 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other standard 40mm bore ISO 15552 cylinders from brands like Festo or SMC without altering mounting hardware.
