This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X10, 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 SI100X10
The AirTAC SI100 Standard Cylinder SI100X10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 10mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X10
The AirTAC SI100X10 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 10mm stroke, delivering 3927N of push force at 0.5MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X10. This current-production direct maintains the exact ISO 15552 mounting interface, bore, stroke and output force, fitting existing fixtures perfectly.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S) and cannot accept position sensors.

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 SAI100X10 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 SI100X10 Is Used
High-Force Clamping
Secures heavy metal castings in machining fixtures using 3927N of push force at 0.5MPa without requiring full system pressure.
Short-Stroke Pressing
Performs brief 10mm stamping or riveting operations where a compact 100mm bore delivers immediate high-impact energy.
Rigid Ejection
Ejects dense molded parts from stationary presses, relying on the 25mm carbon steel rod to withstand sudden lateral stresses.
Replacing the Airtac SI100 Standard Cylinder SI100X10 with the SAI100X10
To replace the discontinued SI100X10, order the SAI100X10 and verify your ISO 15552 mounting interface, 100mm bore, 10mm stroke, G1/2 port (PT/G/NPT) and accessory type. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, specify an SAI100X10S. For sizing alternatives, a neighbouring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore provides 6136N. Remember that a standard cylinder drifts on air loss—the cushion only decelerates—so for load holding consider the SAIL lock, BSAI clamp-lock variant, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X10
- ✓ 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 SI100X10 FAQ
Yes, the AirTAC SI100X10 is discontinued. The direct replacement is the SAI100X10. It shares the identical ISO 15552 mounting interface, 100mm bore, 10mm stroke, output force and G1/2 port, fitting seamlessly into your existing setup.
The 100mm bore features a G1/2 port and a 25mm rod. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical maximum of 801kgf at 1.0MPa.
