This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1300, 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 SI80X1300
The AirTAC SI80 Standard Air Cylinder SI80X1300 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 SAI80X1300, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1300
The AirTAC SI80X1300 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 1300 mm stroke. It delivers 2513 N push force at 0.5 MPa through a G3/8 port. AirTAC replaced this legacy unit with the SAI80X1300, a direct upgrade sharing the exact ISO 15552 mounting interface, bore, stroke, output force, and accessories.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Note this specific SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors.

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 SI80X1300 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1300 mm between conveyor lines using 2513 N of thrust at 0.5 MPa, requiring external guides to support the extended rod.
Large Press Ejection
Ejects molded components from wide press beds, relying on the 36 mm adjustable air cushions at both ends to decelerate the 80 mm bore safely.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1300 with the SAI80X1300
To replace the SI80X1300, order the SAI80X1300. Verify your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/8 port thread (PT/G/NPT), and the M20x1.5 rod end. If you need position sensing, select an SAI model with the S magnet suffix, as this non-S SKU cannot hold a switch. For sizing alternatives, dropping to a 63 mm bore yields 1559 N push at 0.5 MPa, while stepping up to 100 mm provides 3927 N. Because this is a 1300 mm 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 variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1300
- ✓ 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 SI80X1300 FAQ
Yes, the SI80X1300 is discontinued. The direct replacement is the AirTAC SAI80X1300. It shares the identical ISO 15552 mounting interface, 80 mm bore, 1300 mm stroke, output force, and G3/8 port, fitting directly into your existing fixtures.
This double-acting cylinder uses a G3/8 air port. It generates 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 force of 513 kgf at 1.0 MPa.
