This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X1220, 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 SI80X1220
The AirTAC SI80 Standard Air Cylinder SI80X1220 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1220mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X1220, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X1220
The AirTAC SI80X1220 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 1220mm stroke. Delivering 2513N push force at 0.5MPa via a G3/8 port, it is replaced by the SAI80X1220. This direct upgrade shares the exact interface, bore, stroke, force, port and mounting.
The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds SAIL, SAIF and BSAI variants the SI lacked. Note: this non-S SKU lacks a magnet and cannot take a sensor.

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 SI80X1220 Is Used
Long-Stroke Diversion
Pushes heavy pallets laterally across transfer lines using the 1220mm stroke and 2513N force at 0.5 MPa.
Automated Press Clamping
Secures large sheet metal housings during machining, relying on 3518N push force at 0.7 MPa.
Replacing the Airtac SI80 Standard Air Cylinder SI80X1220 with the SAI80X1220
To replace the SI80X1220, order the SAI80X1220. Confirm the ISO 15552 mounting interface, 80mm bore, 1220mm stroke, G3/8 port (PT/G/NPT threads), and mounting accessory. This non-magnet SKU cannot accept a CS1-B/DS1-B sensor. For sizing, a 63mm bore yields 1559N [email protected], while a 100mm bore yields 3927N. At 1220mm, use external guides to prevent rod bending and side-load damage. The cushion only decelerates; for load holding on air loss, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X1220
- ✓ 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 SI80X1220 FAQ
Yes, the SI80X1220 is discontinued. The direct replacement is the SAI80X1220, which shares the same ISO 15552 mounting interface, 80mm bore, 1220mm stroke, output force, G3/8 port, and accessories.
It features a G3/8 air port and provides 2513N push / 2268N pull at 0.5 MPa, 3518N push at 0.7 MPa, 4523N push at 0.9 MPa, and a maximum theoretical force of 513 kgf at 1.0 MPa.
