This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X700, 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 SI100X700
The AirTAC Airtac SI100 Standard Cylinder SI100X700 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 700mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X700, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X700
The AirTAC SI100X700 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 700mm stroke. Delivering 3927N push force at 0.5MPa via a G1/2 port, it is replaced by the SAI100X700. This direct upgrade retains identical ISO 15552 mounting dimensions, bore, and output force.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. Note this SKU lacks a magnet, so it cannot accept CS1-B/DS1-B sensors.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |

Where the Airtac SI100 Standard Cylinder SI100X700 Is Used
Large Press Ejection
Provides the 3927N push at 0.5MPa needed to eject heavy stamped parts from a press bed over a 700mm travel distance.
Pallet Diversion
Actuates a heavy-duty diverter arm across a wide conveyor belt, utilizing the 700mm stroke to route large pallets securely.
Replacing the Airtac SI100 Standard Cylinder SI100X700 with the SAI100X700
To replace the SI100X700, order the SAI100X700 direct. Verify the ISO 15552 interface, 700mm stroke, G1/2 port, and M20x1.5 rod thread. Because this 700mm stroke is long, use external guides to prevent rod bending and side-load wear. For sizing, a neighboring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore yields 6136N. This plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant. The no-magnet body cannot support position sensing.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X700
- ✓ 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 SI100X700 FAQ
Yes, the AirTAC SI100X700 is discontinued. The direct replacement is the SAI100X700. It is dimensionally interchangeable per ISO 15552, keeping the same 100mm bore, 700mm stroke, force, and G1/2 port, so it fits existing fixtures directly.
This double-acting cylinder uses a G1/2 port. It delivers 3927N push and 3681N pull at 0.5MPa, 5497N push at 0.7MPa, 7068N push at 0.9MPa, and a maximum theoretical force of 801kgf at 1.0MPa.
