About the Airtac SAI40 Standard Air Cylinder SAI40AX220
The AirTAC SAI40X220 is a double-acting ISO 15552 profile cylinder offering a 220 mm stroke. In the 40 mm bore class, it generates 628 N of push force at 0.5 MPa and 879 N at 0.7 MPa, making it well-suited for medium-duty handling and positioning tasks.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. It uses PT tapered port threading and lacks a built-in magnet, meaning position sensing via CMSE or DMSE switches is not enabled for this particular unit.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX220 Is Used
Medium-Duty Handling
Drives linear movement for automated clamps and mid-force press operations requiring 879 N of push force at 0.7 MPa.
Material Diverting
Actuates sorting gates and indexing mechanisms on packaging lines where a 220 mm stroke is necessary to clear product flow.
Equipment Stands
Raises and lowers tooling fixtures, utilizing the SUS420J2 stainless steel rod to resist moisture in factory environments.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX220 the Right Cylinder?
If an application requires less force, stepping down to the 32 mm bore yields 563 N at 0.7 MPa, whereas moving up to the 50 mm bore provides 1374 N at 0.7 MPa. Because this 220 mm stroke is substantial, side loads can cause rod-bearing bending; utilizing an external guide or a fully guided cylinder is strongly recommended to prevent premature wear.
The standardized ISO 15552 mounting interface allows this profile cylinder to serve as a direct replacement for other ISO 15552 units without altering the machine footprint. If the machinery must maintain its position after air pressure is removed or exhausted, this standard cylinder will drift, so the SAIL pneumatic lock variant or an external pilot-operated check valve should be specified instead.
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 SAI40AX220 FAQ
The 40 mm bore generates 628 N of push force and 528 N of pull force at 0.5 MPa. At 0.7 MPa, the push force increases to 879 N.
Yes. As a true ISO 15552 profile cylinder, its mounting interface is dimensionally interchangeable with other ISO 15552 cylinders, allowing it to serve as a direct replacement without changing the machine layout.
