This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI100X1350S, 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 SI100X1350S
The AirTAC Airtac SI100 Standard Cylinder SI100X1350S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø100mm bore and 1350mm stroke, G1/2 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI100X1350S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI100 Standard Cylinder SI100X1350S
The AirTAC SI100X1350S is a discontinued double-acting ISO 15552 profile cylinder with a 100mm bore and 1350mm stroke. It delivers a push force of 3927 N at 0.5 MPa via a G1/2 port. AirTAC replaced this legacy unit with the SAI100X1350S, a direct upgrade retaining the exact ISO 15552 mounting interface, bore, stroke, force, and port size.
The SAI upgrade features a modernized piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. The SAI family also introduces lock and valve variants absent from the SI line, such as the SAIL air-released lock and BSAI clamp-lock.

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 SI100X1350S Is Used
Long-Stroke Material Transfer
Moves heavy pallets or chassis components across extended work cells using the 1350mm stroke and 3927 N push force at 0.5 MPa.
Large Assembly Press
Actuates heavy-duty clamping fixtures and press tools where the 100mm bore and G1/2 air supply provide consistent high-force actuation.
Replacing the Airtac SI100 Standard Cylinder SI100X1350S with the SAI100X1350S
To replace the SI100X1350S, order the SAI100X1350S direct equivalent, verifying the ISO 15552 mounting interface, G1/2 port (PT/G/NPT thread options), M20x1.5 rod thread, and the -S magnet for CS1-B/DS1-B sensors. If you need to size both ways, neighboring bores are 80mm and 125mm; at 0.5 MPa, this 100mm bore pushes 3927 N and pulls 3681 N. Because the 1350mm stroke is long, use an external guide to prevent rod bending and side-load damage. A plain cylinder does not hold load without live air—the cushion only decelerates—so for load holding, specify the SAIL or BSAI lock variant, or use an external rod lock.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI100X1350S
- ✓ 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 SI100X1350S FAQ
Yes, the SI100X1350S is discontinued. The direct replacement is the SAI100X1350S. It is dimensionally interchangeable per ISO 15552, matching the 100mm bore, 1350mm stroke, 3927 N force, G1/2 port, and mounting interface.
The 100mm bore uses a G1/2 port. At 0.5 MPa it pushes 3927 N and pulls 3681 N. At 0.7 MPa push is 5497 N, at 0.9 MPa push is 7068 N, and the theoretical max force is 801 kgf at 1.0 MPa.
