This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X192S, 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 SI100X192S
The AirTAC Airtac SI100 Standard Cylinder SI100X192S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 192mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X192S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X192S
The AirTAC SI100X192S is a discontinued double-acting ISO 15552 profile cylinder with a 192 mm non-standard stroke. Delivering 3927 N push force at 0.5 MPa through a G1/2 port, it is directly replaced by the SAI100X192S. This direct upgrade retains the exact bore, stroke, force, port and ISO 15552 mounting interface, fitting existing fixtures perfectly.
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 introduces SAIL, SAIF and BSAI lock variants the SI lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches.

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 SAI100X192S 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 SI100X192S Is Used
Heavy Pressing
Applies the 5497 N push force at 0.7 MPa to seat bearings or assemble heavy mechanical components firmly.
Pallet Diversion
Uses the 192 mm stroke to push heavy pallets onto secondary processing lines within packaging facilities.
Replacing the Airtac SI100 Standard Cylinder SI100X192S with the SAI100X192S
To replace the SI100X192S, order the SAI100X192S. Confirm the ISO 15552 mounting interface, G1/2 port, M20x1.5 rod thread and your -S magnet requirement. Because 192 mm is a non-standard stroke, specify it precisely when ordering the SAI equivalent. If sizing alternatives, neighbouring bores offer different force classes; this 100 mm bore provides 3927 N push at 0.5 MPa. 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 variants. The SAIF variant integrates a 4M valve if needed.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X192S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
