This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X230, 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 SI100X230
The AirTAC SI100 Standard Cylinder SI100X230 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 230mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X230, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X230
The AirTAC SI100X230 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 230mm stroke. It delivers 3927N push and 3681N pull at 0.5MPa through a G1/2 port. AirTAC replaced this legacy unit with the SAI100X230 direct replacement, matching the exact bore, stroke, output force, and ISO 15552 mounting interface for existing fixtures.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this specific SKU lacks a magnet (-S) and cannot take a CS1-B/DS1-B sensor. For high heat, Viton H seals raise the temperature limit to 0-150C.

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 SAI100X230 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 SI100X230 Is Used
Heavy-Duty Pressing
Applies up to 5497N at 0.7MPa for seating bearings and assembling heavy mechanical components.
Pallet Diverting
Handles robust routing and stopping of loaded pallets using the 25mm rod and 100mm bore power.
Replacing the Airtac SI100 Standard Cylinder SI100X230 with the SAI100X230
To replace the SI100X230, order the SAI100X230. Confirm the ISO 15552 mounting interface, 230mm stroke, and G1/2 port (PT/G/NPT thread options). Because this SKU has no magnet, it cannot accept position sensors; if switches are needed, specify an SAI100X230S. Sizing both ways: a neighbouring 80mm bore yields 2513N push at 0.5MPa, while a 125mm bore yields 6136N. The 100mm bore itself reaches 5497N at 0.7MPa. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variants. At 230mm stroke, side-load and rod-bending risks are low, but ensure proper guide alignment.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X230
- ✓ 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 SI100X230 FAQ
Yes, the SI100X230 is discontinued. The direct replacement is the SAI100X230. It features the same ISO 15552 mounting interface, 100mm bore, 230mm stroke, output force, and G1/2 port, fitting directly into existing fixtures.
The G1/2 port is fixed by the 100mm bore. At 0.5MPa it provides 3927N push and 3681N pull. At 0.7MPa push is 5497N, and at 0.9MPa it is 7068N. The theoretical maximum force is 801kgf at 1.0MPa.
