About the Airtac SAI100 Standard Air Cylinder SAI100AX260S
The AirTAC SAI100X260-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 5497 N push force at 0.7 MPa, this 100 mm bore unit is built to handle substantial loads across its 260 mm stroke. The extruded aluminum barrel eliminates tie-rods, providing a clean profile that drops directly into standard ISO 15552 mounting interfaces.
This specific configuration includes a -S magnet for seamless integration with CMSE and DMSE sensor switches fitted into the dual side grooves. It also features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance, alongside PT tapered port threads. Adjustable air cushions at both ends absorb end-of-stroke impact, protecting your machinery.

Where the Airtac SAI100 Standard Air Cylinder SAI100AX260S Is Used
Heavy Stamping
Provides the necessary 5497 N output at 0.7 MPa to drive heavy stamping and forming presses in metal fabrication lines.
Pallet Diversion
Actuates robust routing gates and stoppers on high-mass pallet conveyors, utilizing the 260 mm stroke to clear the transport path.
Plastic Molding
Operates large clamping fixtures and core pulls in injection molding machinery, benefiting from the SUS420J2 rod's durability.
Is the Airtac SAI100 Standard Air Cylinder SAI100AX260S the Right Cylinder?
Selecting this 100 mm bore cylinder makes sense when your application requires upward of 3927 N of push force at 0.5 MPa. If your load requirements are lighter, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, optimizing air consumption. Conversely, heavier payloads up to 6136 N at 0.5 MPa warrant the 125 mm version.
Because the 260 mm stroke exceeds 300 mm, it sits just below the threshold where external side-load guidance becomes critical, though utilizing a guided cylinder design is still recommended for off-center loads. Note that the standard SAI does not hold position upon air loss; for fail-safe load holding, specify the SAIL variant or an external rod lock. This model is fully interchangeable with other ISO 15552 cylinders, matching the G1/2 port, M20x1.5 rod thread, and standard mounting accessories like FA flanges or TC trunnions.
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 SAI100 Standard Air Cylinder SAI100AX260S FAQ
At a standard operating pressure of 0.7 MPa, this 100 mm bore cylinder generates 5497 N of push force and 3681 N of pull force. It can reach a maximum theoretical force of 801 kgf at 1.0 MPa.
No, the standard SAI cylinder relies on adjustable air cushions to decelerate the piston, not to lock it. If your application requires holding a load without continuous air pressure, you should use the SAIL (air-released lock) or BSAI (clamp-lock) variant.
