This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1400S, 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 SI100X1400S
The AirTAC Airtac SI100 Standard Cylinder SI100X1400S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1400mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1400S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1400S
The AirTAC SI100X1400S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1400mm stroke. It delivers 3927N push force at 0.5MPa via a G1/2 port. The direct replacement is the SAI100X1400S, retaining the exact bore, stroke, force, port and mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors.

Where the Airtac SI100 Standard Cylinder SI100X1400S Is Used
Long-Stroke Material Transfer
Drives heavy pallets across extended conveyor sections using the 1400mm stroke and 3927N push force at 0.5MPa.
Large Press Ejection
Ejects heavy formed parts from machinery, utilising the 801kgf maximum theoretical force at 1.0MPa.
Replacing the Airtac SI100 Standard Cylinder SI100X1400S with the SAI100X1400S
To replace this SI100X1400S, order the SAI100X1400S keeping the identical ISO 15552 mounting interface, 100mm bore, 1400mm stroke, G1/2 port and -S magnet. When sizing both ways, dropping to an 80mm bore cuts the 0.5MPa push to 2513N, while a 125mm bore raises it to 6136N. A plain cylinder drifts on air loss as the cushion only decelerates; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Because 1400mm exceeds 300mm, add external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1400S
- ✓ 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 SI100X1400S FAQ
Yes, the SI100X1400S is discontinued. The direct replacement is the SAI100X1400S. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 1400mm stroke, force, G1/2 port and mounting fixtures.
At 0.5MPa it pushes 3927N and pulls 3681N. At 0.7MPa push is 5497N, and at 0.9MPa it is 7068N. The theoretical max force is 801kgf at 1.0MPa. Operating speed is 30-800mm/s, with a 36mm adjustable air cushion at both ends.
