This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1500, 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 SI100X1500
The AirTAC Airtac SI100 Standard Cylinder SI100X1500 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1500mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1500, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1500
The AirTAC SI100X1500 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1500mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa, utilizing a G1/2 port and M20x1.5 rod thread. AirTAC replaced this legacy unit with the SAI100X1500, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, force and port size.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. Because this specific SKU lacks the -S magnet suffix, it cannot accept a CS1-B or DS1-B sensor.

Where the Airtac SI100 Standard Cylinder SI100X1500 Is Used
Long-Stroke Material Transfer
Drives heavy pallets across extended assembly lines where 1500mm travel and 3927N force move substantial loads between stations.
Large Press Ejection
Pushes finished parts out of heavy machinery using 7068N at 0.9MPa, requiring external check valves to prevent drifting.
Replacing the Airtac SI100 Standard Cylinder SI100X1500 with the SAI100X1500
To replace the SI100X1500, order the SAI100X1500 and confirm the ISO 15552 mounting interface, 100mm bore, 1500mm stroke, G1/2 port (PT/G/NPT thread options) and mounting accessory. Because this SKU has no -S magnet, it cannot support position sensing. If sizing up or down, neighbouring bores (80mm or 125mm) change the 0.5MPa push force (2513N or 6136N respectively). Note that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 1500mm stroke, prevent rod bending and side-load damage by using external guides.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1500
- ✓ 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 SI100X1500 FAQ
Yes, the SI100X1500 is discontinued. The direct replacement is the SAI100X1500. It features the same ISO 15552 mounting interface, 100mm bore, 1500mm stroke, output force, G1/2 port and mounting accessories, fitting directly into existing fixtures.
This 100mm bore cylinder uses a G1/2 port. It generates 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.
