This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1230S, 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 SI100X1230S
The AirTAC Airtac SI100 Standard Cylinder SI100X1230S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1230mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1230S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1230S
The AirTAC SI100X1230S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1230mm stroke. Delivering 3927N push force at 0.5MPa through a G1/2 port, it is replaced by the direct replacement SAI100X1230S. This upgrade retains identical mounting and force but uses an upgraded piston seal with two Y-shaped elements for low start-up pressure. The SAI family also adds SAIL, SAIF, and BSAI variants the SI lacked.
The original -S magnet supports legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. Rod material options include carbon steel, SUS420J2, or SUS304, and Viton H seals raise the temperature limit to 150C.

Where the Airtac SI100 Standard Cylinder SI100X1230S Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across 1230mm gaps between conveyor lines using 3927N of thrust at 0.5MPa.
Large Assembly Press
Drives large fixture components or clamping arms over a long reach, benefiting from the 36mm adjustable air cushions at both ends.
Replacing the Airtac SI100 Standard Cylinder SI100X1230S with the SAI100X1230S
To replace this SI100X1230S, order the SAI100X1230S direct: it matches the ISO 15552 mounting interface, 100mm bore, 1230mm stroke, G1/2 port, and M20x1.5 rod thread. Retain your existing mounting accessory (LB, FA, TC, etc.) and confirm the -S magnet for current AirTAC switches. If you need less force, step down to an 80mm bore (2513N push); if you need more, a 125mm bore yields 6136N. Because this is a long 1230mm stroke, use an external guide to prevent rod bending and side-load wear. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1230S
- ✓ 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 SI100X1230S FAQ
Yes, the SI100X1230S is discontinued. The direct replacement is the SAI100X1230S. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 1230mm stroke, G1/2 port, and mounting interface.
It features a G1/2 port and M20x1.5 rod thread. Force ratings are 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a theoretical max of 801kgf at 1.0MPa. Operating speed is 30-800mm/s.
