This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1700, 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 SI100X1700
The AirTAC Airtac SI100 Standard Cylinder SI100X1700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1700
The AirTAC SI100X1700 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1700mm stroke. Because 1700mm exceeds the 1500mm standard maximum, this is a non-standard, made-to-order length. It delivers 3927 N push force at 0.5 MPa. The direct replacement is the SAI100X1700, retaining the exact same G1/2 port, M20x1.5 rod thread, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and extended life. This SKU lacks a magnet and cannot accept a sensor. For load holding, note that the cushion only decelerates; use an external rod lock or the SAIL/BSAI lock variants.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI100X1700 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI100X1700 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 SI100X1700 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1.7 meters between conveyor lines using 3927 N of thrust, guided by external rails to prevent rod bending.
Large Press Ejection
Ejects heavy formed parts from industrial presses over a long 1700mm distance, relying on the 36mm adjustable air cushions for end-of-stroke deceleration.
Replacing the Airtac SI100 Standard Cylinder SI100X1700 with the SAI100X1700
To replace the SI100X1700, order the SAI100X1700 direct equivalent. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G1/2 port, and M20x1.5 rod thread. Since this 1700mm stroke exceeds the 1500mm standard maximum, expect a made-to-order lead time. Crucially, a 1700mm stroke requires external guide rails to prevent rod bending and side-load damage. Sizing both ways: if you need less force, the 80mm bore yields 2513 N push at 0.5 MPa; if you need more, the 125mm bore yields 6136 N. This non-magnet SKU cannot take a sensor; if position feedback is needed, select an SAI100X1700S and use current AirTAC switches. For suspended loads that must not drift on air loss, add a pilot check valve or specify the SAIL or BSAI lock variant, as the standard cushion only decelerates.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1700
- ✓ 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 SI100X1700 FAQ
Yes, the AirTAC SI100X1700 is discontinued. The direct replacement is the SAI100X1700. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 1700mm stroke, G1/2 port, and mounting interface.
This 100mm bore cylinder uses a G1/2 air port. It generates 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, and a theoretical maximum of 801 kgf at 1.0 MPa. The 1700mm stroke is non-standard and made-to-order.
