This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X262S, with the same bore, stroke, output force, port and mounting, so it fits the same application. The SAI replacement keeps the same ISO 15552 mounting interface, bore, stroke, output force and accessories, so it drops straight into existing fixtures. It is the current-production version of this cylinder with an upgraded piston seal.
Airtac SI100 Standard Cylinder SI100X262S
The AirTAC Airtac SI100 Standard Cylinder SI100X262S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 262mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X262S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X262S
The AirTAC SI100X262S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 262mm stroke. It delivers 3927N push force at 0.5MPa via a G1/2 port. The direct replacement is SAI100X262S, retaining identical mounting, force, and stroke.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure. The SAI family adds SAIL, SAIF, and BSAI lock variants. This -S model uses CS1-B/DS1-B sensors; no-S SKUs lack magnet sensing.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X262S Is Used
Heavy Press Clamping
Ideal for securing heavy steel plates during machining, utilizing the 3927N push force at 0.5MPa to hold parts rigidly against the fixture.
Large Component Ejection
Ejects molded or stamped components from heavy machinery, where the 36mm adjustable air cushions absorb kinetic energy at stroke ends.
Replacing the Airtac SI100 Standard Cylinder SI100X262S with the SAI100X262S
To replace the SI100X262S, order SAI100X262S. Verify the ISO 15552 interface, 100mm bore, 262mm stroke (nonstandard), G1/2 port, and M20x1.5 rod thread. The -S suffix means it has a piston magnet for CS1-B/DS1-B switches (the SAI uses current AirTAC switches). For sizing, neighboring bores are 80mm (2513N [email protected]) and 125mm (6136N [email protected]). A plain cylinder drifts on air loss; the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or SAIL/BSAI variant. At 262mm stroke, use guide rails to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X262S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI100 Standard Cylinder SI100X262S FAQ
Yes, the SI100X262S is discontinued. The direct replacement is the SAI100X262S. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 262mm stroke, G1/2 port, and mounting interface.
The G1/2 port bore delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a max force of 801kgf at 1.0MPa. Speed is 30-800mm/s.
