This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X860S, 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 SI80X860S
The AirTAC SI80 Standard Air Cylinder SI80X860S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 860mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X860S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X860S
The AirTAC SI80X860S is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 860mm stroke. Generating 2513N push force at 0.5MPa via a G3/8 port, it is replaced by the SAI80X860S. This direct upgrade shares identical ISO 15552 mounting, force, and stroke. The SAI features an upgraded piston seal using two Y-shaped one-way elements for low start-up pressure and long life.
The original -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI uses current AirTAC switches. Rod material options include carbon steel, SUS420J2, or SUS304, and a Viton H seal raises the temperature range to 150C.

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 SI80X860S Is Used
Long-Stroke Diversion
Pushes heavy pallets across transfer lines with its 860mm reach and 2513N force, requiring external guides to prevent rod bending.
Press Ejection
Cycles parts out of machinery at 30-800mm/s, with the adjustable 36mm air cushions decelerating the payload at stroke end.
Replacing the Airtac SI80 Standard Air Cylinder SI80X860S with the SAI80X860S
To replace the SI80X860S, order the SAI80X860S, confirming the ISO 15552 interface, 80mm bore, 860mm stroke, G3/8 port, and M20x1.5 rod thread. Retain your mounting accessory (LB, FA, TC, etc.) and -S magnet option. Sizing checks: a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. Because this is an 860mm stroke, external guides are recommended to prevent rod bending and side-load wear. A plain cylinder drifts on air loss; for load holding, use the SAIL lock, BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X860S
- ✓ 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 SI80X860S FAQ
Yes, the SI80X860S is discontinued. The direct replacement is the SAI80X860S. It shares the same ISO 15552 mounting interface, 80mm bore, 860mm stroke, 2513N force, and G3/8 port, fitting existing fixtures perfectly.
The 80mm bore uses a G3/8 port. It delivers 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical max of 513kgf at 1.0MPa.
