This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X10S, 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 SI100X10S
The AirTAC Airtac SI100 Standard Cylinder SI100X10S 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 SAI100X10S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X10S
The AirTAC SI100X10S is a discontinued double-acting ISO 15552 profile cylinder. In the 100mm bore class it delivers 3927N push and 3681N pull at 0.5MPa, operating at 30-800mm/s through a G1/2 port. The direct successor is the SAI100X10S, retaining the identical 10mm stroke, M20x1.5 rod thread, and 36mm adjustable cushions.
This SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. Your -S suffix means a magnet for CS1-B/DS1-B sensors, though 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 | — |

Where the Airtac SI100 Standard Cylinder SI100X10S Is Used
Short-Stroke Clamping
Ideal for high-force 3927N clamping of heavy steel plates in machining fixtures, utilising the 10mm stroke for rapid, repeatable actuation.
Press Ejection
Provides robust 100mm bore ejection force to knock out dense stamped parts from heavy presses, relying on the 36mm adjustable cushions to absorb impact.
Spot Holding
Secures large components during robotic welding, delivering firm downward holding pressure without requiring the full travel of a longer actuator.
Replacing the Airtac SI100 Standard Cylinder SI100X10S with the SAI100X10S
To replace the SI100X10S, order the SAI100X10S. Verify the ISO 15552 mounting interface, the G1/2 port, and your -S magnet requirement. Sizing both ways: a neighbouring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore offers 6136N. For this 100mm bore, push forces are 3927N at 0.5MPa, 5497N at 0.7MPa, and 7068N at 0.9MPa. Because this is a plain cylinder, it cannot hold a load without live air; the cushion only decelerates. For load holding, use an external rod lock, a pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X10S
- ✓ 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 SI100X10S FAQ
Yes, the AirTAC SI100X10S is discontinued. The direct replacement is the SAI100X10S. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 10mm stroke, 3927N force, G1/2 port, and mounting fixtures.
The 100mm bore features a G1/2 port. Theoretical forces are 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a maximum of 801kgf at 1.0MPa.
