About the Airtac SAI40 Standard Air Cylinder SAI40AX260S
The AirTAC SAI40X260-S is a double-acting ISO 15552 profile cylinder featuring a 40mm bore and a 260mm stroke. It generates 628N of push force and 528N of pull force at 0.5 MPa, making it well-suited for mid-range automation tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a -S magnet for use with CMSE or DMSE sensor switches and utilizes a PT tapered port thread. The piston rod is constructed from SUS420J2 stainless steel (material code A), offering excellent resistance to moisture and corrosion in harsh environments.

Where the Airtac SAI40 Standard Air Cylinder SAI40AX260S Is Used
Package Sorting
Handles mid-range pushing and diverting on packaging lines using the integrated magnet for end-of-stroke position sensing.
Material Handling
Provides 628N of thrust at 0.5 MPa for lifting and transferring components between workstations.
Assembly Automation
Drives clamping and indexing mechanisms where the SUS420J2 stainless steel rod prevents corrosion from environmental exposure.
Is the Airtac SAI40 Standard Air Cylinder SAI40AX260S the Right Cylinder?
With a 260mm stroke, this 40mm bore cylinder sits comfortably within the standard range, but the extended length means side loads must be carefully managed. For applications exceeding 300mm, stepping up to a guided cylinder or adding external guide rails is recommended to prevent rod-bearing bending. If your process requires higher thrust, the neighboring 50mm bore provides 982N of push force at 0.5 MPa.
Because this is a standard double-acting cylinder, it will not hold a load if air pressure is lost or the valve is centered. For position holding without live pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, requiring only a 40mm bore, 260mm stroke, G1/4 port, and your preferred mounting accessory like an FA flange or TC trunnion.
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 SAI40AX260S FAQ
At 0.5 MPa, the SAI40X260-S provides 628N of push force and 528N of pull force. If operated at 0.7 MPa, the push force increases to 879N.
Yes, the SAI40X260-S is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders with a 40mm bore, 260mm stroke, and G1/4 port.
