This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X710S, 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 SI80X710S
The AirTAC SI80 Standard Air Cylinder SI80X710S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 710mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X710S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X710S
The AirTAC SI80X710S is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 710 mm stroke. It delivers 2513 N push force at 0.5 MPa via a G3/8 port. AirTAC replaced this legacy unit with the SAI80X710S, a direct upgrade retaining the exact interface, bore, stroke, output force, and mounting dimensions.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. The SAI family also introduces SAIL, SAIF, and BSAI lock variants the SI line lacked. Your -S magnet works with legacy CS1-B/DS1-B sensors, though 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 SI80X710S Is Used
Long-Stroke Diverting
Pushes heavy pallets laterally across transfer lines using the full 710 mm travel, relying on the 2513 N push force at 0.5 MPa to overcome friction.
Large Press Ejection
Clears heavy stamped parts from press beds, utilizing the adjustable 36 mm air cushions at both ends to decelerate the 25 mm rod smoothly.
Replacing the Airtac SI80 Standard Air Cylinder SI80X710S with the SAI80X710S
To replace the SI80X710S, order the SAI80X710S. Confirm the ISO 15552 mounting interface, 80 mm bore, 710 mm stroke, G3/8 port (PT/G/NPT thread options), and your specific mounting accessory (LB, FA, TC, etc.). The -S suffix means a piston magnet is present for CS1-B/DS1-B switches; the SAI replacement uses current AirTAC switches. Sizing both ways: the neighboring 63 mm bore yields 1559 N push at 0.5 MPa, while the 100 mm bore yields 3927 N. A plain cylinder does not hold load without live air; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. Because the 710 mm stroke is long, use external guides to prevent rod bending and side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X710S
- ✓ 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 SI80X710S FAQ
Yes, the SI80X710S is discontinued. The direct replacement is the SAI80X710S. It shares the same ISO 15552 mounting interface, 80 mm bore, 710 mm stroke, output force, and G3/8 port, fitting existing fixtures perfectly.
The 80 mm bore features a G3/8 port and a 25 mm rod. It delivers 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.
