This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX600, 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 SI80BX600
The AirTAC SI80 Standard Air Cylinder SI80BX600 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 600mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX600, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX600
The AirTAC SI80BX600 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 600 mm stroke. It delivers 2513 N push force at 0.5 MPa via a G3/8 port. The SUS304 stainless rod suits corrosive settings. This SKU lacks a magnet, so it cannot accept a sensor. The direct is the SAI80BX600.
The SAI upgrade keeps the exact ISO 15552 mounting interface, bore, stroke and force, but adds a two Y-shaped one-way piston seal for low start-up pressure. For high heat, Viton H seals raise the limit to 150 C.

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 SI80BX600 Is Used
Corrosive Fluid Handling
The SUS304 stainless rod operates reliably in washdown and chemical environments, driving 600 mm strokes for valve actuation.
Heavy Transfer Pushing
With 2513 N push at 0.5 MPa, it shunts heavy pallets or workpieces along high-throughput material handling lines.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX600 with the SAI80BX600
To replace the SI80BX600, order the SAI80BX600. Verify the ISO 15552 interface, 80 mm bore, 600 mm stroke, G3/8 port and SUS304 rod. This non-magnet SKU cannot take a switch; if sensing is needed, select an SAI80X600S and use current AirTAC switches. The 513 kgf max suits heavy loads; sizing down, a 63 mm bore gives 318 kgf. At 600 mm stroke, use external guides to prevent rod bending. The cushion only decelerates; for load holding on air loss, use an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX600
- ✓ 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 SI80BX600 FAQ
Yes, the SI80BX600 is discontinued. The direct replacement is the SAI80BX600. It shares the identical ISO 15552 mounting interface, 80 mm bore, 600 mm stroke, 513 kgf max force, G3/8 port and SUS304 rod, fitting existing fixtures perfectly.
It features a G3/8 air port. The thrust ratings are: 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 of 513 kgf at 1.0 MPa.
