This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1300STC, 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 SI80X1300STC
The AirTAC SI80 Standard Air Cylinder SI80X1300STC 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 SAI80X1300STC, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1300STC
The AirTAC SI80X1300STC is a discontinued double-acting ISO 15552 profile cylinder with a 1300 mm stroke, delivering 2513 N push and 2268 N pull at 0.5 MPa. It features a G3/8 port, M20x1.5 rod thread, and a built-in magnet for CS1-B/DS1-B sensors. AirTAC replaced this legacy unit with the SAI80X1300STC, a direct replacement sharing the exact ISO 15552 mounting interface, TC trunnion mount, bore, and force.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked.

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 SI80X1300STC Is Used
Long-Stroke Transfer
Moves heavy pallets 1300 mm between machining centers using the 2513 N push force and TC trunnion mount to absorb alignment shifts.
Large Part Ejection
Ejects molded assemblies from press beds, utilizing the 36 mm adjustable air cushions to decelerate the payload at stroke end.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1300STC with the SAI80X1300STC
To replace the SI80X1300STC, order the SAI80X1300STC and confirm the ISO 15552 TC trunnion interface, 80 mm bore, 1300 mm stroke, G3/8 port, and -S magnet for current AirTAC switches. If you need more force, the 100 mm bore offers 3927 N push at 0.5 MPa; if less, the 63 mm bore provides 1559 N. Because this is a 1300 mm long stroke, use an external guide to prevent rod bending and side loads. A plain cylinder drifts on air loss—the cushion only decelerates—so for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1300STC
- ✓ 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 SI80X1300STC FAQ
Yes, the SI80X1300STC is discontinued. The direct replacement is the SAI80X1300STC. It shares the identical ISO 15552 mounting interface, 80 mm bore, 1300 mm stroke, G3/8 port, and TC mount, fitting existing fixtures perfectly.
The 80 mm bore uses a G3/8 port and M20x1.5 rod thread. 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 max of 513 kgf at 1.0 MPa. Speed is 30-800 mm/s.
