About the Airtac SAI40 Standard Air Cylinder SAI40AX210
The AirTAC SAI40X210 is a double-acting ISO 15552 profile cylinder engineered to deliver 628N of push force at 0.5 MPa. Its 210mm stroke provides the extended travel needed for mid-range material handling and assembly automation. Built with a standardized mounting interface, it serves as a direct replacement for any ISO 15552 profile cylinder.
This specific configuration utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid connections use PT tapered threads, and because it lacks a built-in magnet, it operates without electronic position sensing.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX210 Is Used
Component Clamping
Secures medium-sized machined parts during secondary milling or drilling operations using its 879N push force at 0.7 MPa.
Package Diverting
Actuates diverter arms on packaging lines, utilizing the 210mm stroke to push cartons cleanly between parallel conveyors.
Gate Operation
Controls access gates on automated manufacturing cells, providing reliable cycling with adjustable air cushions at both ends.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX210 the Right Cylinder?
Choose this 40mm bore when an application requires more power than a 32mm cylinder (which provides only 402N at 0.5 MPa) but where the larger 50mm bore is physically unnecessary. For this 210mm stroke, be mindful of side loads; an unsupported piston rod can bend under lateral stress, so utilize external guide rails or a guided cylinder carriage to protect the rod bearing.
If your workflow demands that the load remains suspended or locked in place after air pressure is cut off, the standard SAI will not suffice as it allows piston drift. In those scenarios, specify the SAIL variant for an air-released lock or the BSAI for bidirectional clamping.
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 SAI40AX210 FAQ
At a standard operating pressure of 0.5 MPa, this 40mm bore cylinder 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 SAI40X210 is dimensionally interchangeable per ISO 15552. You can swap it directly with other ISO 15552 profile cylinders by matching the 40mm bore, 210mm stroke, and PT port locations.
