This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1400, 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 SI80X1400
The AirTAC SI80 Standard Air Cylinder SI80X1400 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1400mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1400, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1400
The AirTAC SI80X1400 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 1400 mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa using a G3/8 port. The direct replacement is the SAI80X1400, matching the exact bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. This specific SKU lacks the -S magnet, so it cannot accept CS1-B/DS1-B sensors. For high heat, Viton H seals raise the -20 to +70 C range to 150 C.

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 SI80X1400 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets or workpieces across a 1400 mm span using 2513 N of thrust at 0.5 MPa, requiring external guide rails to prevent rod bending.
Large Fixture Positioning
Shifts heavy machining fixtures into the working zone, taking advantage of the 36 mm adjustable air cushions at both ends to decelerate the 80 mm bore smoothly.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1400 with the SAI80X1400
To replace the SI80X1400, order the SAI80X1400. Verify your ISO 15552 mounting accessories (LB, FA, CA, TC), the G3/8 port thread (PT/G/NPT) and the M20x1.5 rod end. Because this SKU has no -S magnet, it cannot support position sensing; if switches are needed, order an SAI80X1400S. Sizing both ways: a 63 mm bore gives 1559 N push at 0.5 MPa, while a 100 mm bore gives 3927 N. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external pilot check valve or the SAIL/BSAI lock variant. At 1400 mm, prevent rod bending by guiding the load externally to avoid side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1400
- ✓ 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 SI80X1400 FAQ
Yes, the SI80X1400 is discontinued. The direct replacement is the SAI80X1400. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 80 mm bore, 1400 mm stroke, 513 kgf max force, G3/8 port and mounting fixtures.
It uses a G3/8 air port. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, 4523 N push at 0.9 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa. Operating speed is 30-800 mm/s.
