This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1650, 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 SI100X1650
The AirTAC Airtac SI100 Standard Cylinder SI100X1650 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1650mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1650, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1650
The AirTAC SI100X1650 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1650mm stroke. Because 1650mm exceeds the 1500mm standard maximum for this bore, it is a non-standard, made-to-order length. It delivers 3927 N push force at 0.5 MPa via a G1/2 port.
You must order the direct replacement SAI100X1650. It shares the exact ISO 15552 mounting interface, bore, stroke, and force. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This no-magnet SKU cannot take a sensor.

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 SAI100X1650 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 SI100X1650 Is Used
Long-Stroke Material Transfer
Drives large pallets across extended conveyor sections, utilizing the 1650mm reach and 3927 N thrust to push heavy goods between processing stations.
High-Bay Ejection
Ejects packaged inventory from deep storage racking. The 100mm bore provides the robust push force needed to overcome carton friction over long distances.
Vertical Lowering Arrest
Manages the descent of heavy fixtures. The adjustable 36mm air cushions decelerate the load near stroke end, though an external guide is required for this 1650mm rod.
Replacing the Airtac SI100 Standard Cylinder SI100X1650 with the SAI100X1650
To replace the SI100X1650, order the SAI100X1650. Confirm the ISO 15552 mounting accessory (LB, FA, CA, TC) and the G1/2 port. This non-standard 1650mm stroke requires a made-to-order request. Because the stroke exceeds 300mm, use an external guide to prevent rod bending and side-load damage. Sizing both ways: the 80mm bore yields 2513 N push at 0.5 MPa, while the 125mm bore yields 6136 N. The plain cylinder does not hold load 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 SAI family also adds the SAIF self-valve option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1650
- ✓ 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 SI100X1650 FAQ
Yes, the SI100X1650 is discontinued. The direct replacement is the SAI100X1650. It shares the same ISO 15552 mounting interface, 100mm bore, 1650mm stroke, force, and G1/2 port, fitting existing fixtures perfectly.
It features a G1/2 air port and M20x1.5 rod thread. Force ratings are: 3927 N push and 3681 N pull at 0.5 MPa; 5497 N push at 0.7 MPa; 7068 N push at 0.9 MPa; with a theoretical max of 801 kgf at 1.0 MPa.
