This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X110FA, 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 SI100X110FA
The AirTAC Airtac SI100 Standard Cylinder SI100X110FA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 110mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X110FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X110FA
The AirTAC SI100X110FA is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 110mm stroke. It delivers 3927N push force at 0.5MPa via a G1/2 port. Because this legacy unit lacks the -S magnet option, it cannot accept a position sensor. The direct replacement is the current-production SAI100X110FA.
The SAI100X110FA maintains the exact same ISO 15552 mounting interface, FA flange, stroke and output force. It upgrades the internals with two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family also adds SAIL and BSAI lock variants absent from the SI line.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |
| Max (@1.0 MPa) | 801 kgf | |
The SAI100X110FA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI100 Standard Cylinder SI100X110FA Is Used
Heavy Press Clamping
Ideal for securing heavy fabrication frames in machining stations, utilizing the 3927N push force at 0.5MPa to hold components rigidly under tool load.
Pallet Diverting
Drives robust routing gates on high-capacity packaging lines where the 110mm stroke and 801kgf maximum theoretical force shift fully loaded pallets laterally.
Replacing the Airtac SI100 Standard Cylinder SI100X110FA with the SAI100X110FA
To replace the SI100X110FA, order the SAI100X110FA. Verify the ISO 15552 FA flange interface, 100mm bore, 110mm stroke, M20x1.5 rod thread and G1/2 port (PT/G/NPT). This SKU has no magnet, so it cannot support CS1-B/DS1-B sensors; order an SAI with the S suffix if you need sensing. Sizing both ways: a neighbouring 80mm bore yields 2513N [email protected], while the 125mm bore yields 6136N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X110FA
- ✓ 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 SI100X110FA FAQ
Yes, the SI100X110FA is discontinued. The direct replacement is the SAI100X110FA. It is dimensionally interchangeable per ISO 15552, retaining the same FA flange mount, 100mm bore, 110mm stroke, output force and G1/2 port, but features an upgraded double Y-shaped piston seal for lower start-up pressure.
This 100mm bore cylinder uses a G1/2 port. Force output is 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a maximum theoretical force of 801kgf at 1.0MPa. The piston rod is 25mm with an M20x1.5 thread.
