This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X330, 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 SI100X330
The AirTAC Airtac SI100 Standard Cylinder SI100X330 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 330mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X330, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X330
The AirTAC SI100X330 is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 330mm stroke. It delivers 3927 N push force at 0.5 MPa through a G1/2 port. The direct replacement is the SAI100X330, which shares identical mounting, output, and dimensions.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnet SKU cannot accept a sensor, and the Viton H seal option extends heat resistance to 150 C.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3927 N | 3682 N |
| 0.7 MPa | 5498 N | — |

Where the Airtac SI100 Standard Cylinder SI100X330 Is Used
Heavy-Duty Pressing
Drives large stamping or forming dies requiring substantial thrust, utilizing the 3927 N push force at 0.5 MPa to seat components reliably.
Pallet Diversion
Actuates heavy lane guides or diverter arms on packaging lines, where the 330mm stroke provides the reach needed to redirect wide loads.
Replacing the Airtac SI100 Standard Cylinder SI100X330 with the SAI100X330
To replace the SI100X330, order the SAI100X330. Confirm the ISO 15552 interface, 100mm bore, 330mm stroke, G1/2 port (PT/G/NPT), and mounting accessory. Because this is a non-magnet model, it cannot hold a switch; if sensing is needed, specify an SAI100X330S. At 0.5 MPa the 100mm bore yields 3927 N push, while the 80mm neighbour yields 2513 N. For the 330mm stroke, use external guides to prevent rod bending and side-load damage. A plain cylinder drifts on air loss; for load holding, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X330
- ✓ 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 SI100X330 FAQ
Yes, the AirTAC SI100X330 is discontinued. The direct replacement is the SAI100X330. It is dimensionally interchangeable per ISO 15552, retaining the same 100mm bore, 330mm stroke, output force, G1/2 port, and mounting interface to fit existing fixtures directly.
This double-acting cylinder uses a G1/2 air port. The thrust 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, and a maximum theoretical force of 801 kgf at 1.0 MPa.
