About the Airtac SAI40 Standard Air Cylinder SAI40AX100
The AirTAC SAI40X100 is a double-acting ISO 15552 profile cylinder offering a 40mm bore and 100mm stroke. It delivers 628N of push force and 528N of pull force at 0.5 MPa, making it a robust choice for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior and integrated mounting interfaces.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads, and because it lacks the -S magnet option, it is optimized purely for mechanical actuation without requiring proximate sensor switches.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX100 Is Used
Component Clamping
Provides reliable 628N clamping force at 0.5 MPa for securing medium-sized metal or plastic parts during machining and assembly processes.
Package Diverting
The 100mm stroke is ideal for actuating diverters and gates on packaging lines, quickly sorting cartons without excessive cycle times.
Material Ejection
Suitable for ejecting molded parts or stamping blanks from presses, utilizing the 879N push force available at 0.7 MPa operating pressure.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX100 the Right Cylinder?
Select this 40mm bore model when an application requires more power than a 32mm bore (which provides 402N push at 0.5 MPa) but does not warrant the larger footprint of a 50mm bore (982N push). The 100mm stroke offers a compact extension length suitable for tight machinery enclosures.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to maintain its position; the adjustable air cushions only decelerate the piston at stroke ends and will not hold a load if air pressure is lost. For direct replacements, ensure the ISO 15552 mounting dimensions, 100mm stroke, and G1/4 port size match your existing fixture.
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 SAI40AX100 FAQ
At a 0.5 MPa operating pressure, the SAI40X100 generates 628N of push force and 528N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 879N.
Yes, the SAI40X100 is dimensionally interchangeable per ISO 15552 profile standards. You can drop it into existing mounts matching the 40mm bore and 100mm stroke specifications.
