This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1300S, 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 SI80 Standard Air Cylinder SI80X1300S
The AirTAC SI80 Standard Air Cylinder SI80X1300S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1300mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1300S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1300S
The AirTAC SI80X1300S is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. The direct replacement is the SAI80X1300S, matching the 80 mm bore, 1300 mm stroke, and ISO 15552 mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. This SI-SKU's built-in magnet works with legacy CS1-B/DS1-B sensors, while SAI uses current AirTAC switches.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |

Where the Airtac SI80 Standard Air Cylinder SI80X1300S Is Used
Long-Stroke Diversion
Pushes heavy pallets across 1300 mm transfer lines where the 2513 N force at 0.5 MPa handles lateral shifting easily.
Automated Press Ejection
Cycles large formed parts out of hydraulic presses, relying on the 36 mm adjustable air cushions to absorb kinetic energy.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1300S with the SAI80X1300S
To replace the SI80X1300S, order the SAI80X1300S. Verify the ISO 15552 mounting interface, G3/8 port, M20x1.5 rod thread, and the -S magnet for position sensing. If you need less force, a 63 mm bore gives 1559 N push at 0.5 MPa; if you need more, a 100 mm bore yields 3927 N. For load holding on air loss, note that a plain cylinder drifts and the air cushion only decelerates near stroke end. Use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Because 1300 mm is a long stroke, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1300S
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI80 Standard Air Cylinder SI80X1300S FAQ
Yes, the SI80X1300S is discontinued. The direct replacement is the SAI80X1300S. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 1300 mm stroke, 2513 N force, G3/8 port, and mounting fixtures.
At 0.5 MPa it provides 2513 N push and 2268 N pull. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical max force is 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
