This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X223S, 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 SI100X223S
The AirTAC SI100 Standard Cylinder SI100X223S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 223mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X223S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X223S
The AirTAC SI100X223S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 223mm stroke. It delivers 3927 N push force at 0.5 MPa. AirTAC replaced this legacy unit with the SAI100X223S, a direct upgrade sharing the exact ISO 15552 mounting interface, G1/2 port, and 36mm cushions.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked.

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 SAI100X223S 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 SI100X223S Is Used
Heavy Press Clamping
Ideal for applying substantial 3927 N clamping force to secure heavy fabrication components during machining or welding operations.
Pallet Diverting
Provides the robust thrust needed to redirect large loaded pallets on material handling lines with precise 223mm actuation.
Replacing the Airtac SI100 Standard Cylinder SI100X223S with the SAI100X223S
To replace the SI100X223S, order the SAI100X223S. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G1/2 port, and the -S magnet for CS1-B/DS1-B sensors (the SAI uses current AirTAC switches). Sizing both ways: a neighboring 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore offers 6136 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. At 223mm stroke, ensure guide alignment to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X223S
- ✓ 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 SI100X223S FAQ
Yes, the SI100X223S is discontinued. The direct replacement is the SAI100X223S. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 223mm stroke, output force, G1/2 port, and mounting interface.
The 100mm bore uses a G1/2 port. Force output is 3927 N push and 3681 N pull at 0.5 MPa, 5497 N push at 0.7 MPa, 7068 N push at 0.9 MPa, and a theoretical maximum of 801 kgf at 1.0 MPa. It features a 25mm rod and 36mm adjustable cushions.
