This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX1000, 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 SI80BX1000
The AirTAC SI80 Standard Air Cylinder SI80BX1000 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX1000, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX1000
The AirTAC SI80BX1000 is a discontinued double-acting ISO 15552 profile cylinder with an extruded aluminum barrel and adjustable air cushions at both ends. This 80mm bore, 1000mm stroke variant delivers 2513N push and 2268N pull at 0.5MPa. The direct replacement is the SAI80BX1000, which preserves the exact ISO 15552 mounting interface, G3/8 port, and output force. The -B suffix indicates a SUS304 stainless steel piston rod for corrosion resistance.
The SAI80BX1000 upgrade features a redesigned piston seal using two Y-shaped one-way elements for low start-up pressure and extended life. Because this SKU lacks the -S magnet, it cannot accept position switches. For load holding, note that standard cylinders drift on air loss; use an external pilot check valve or the SAIL/BSAI lock variants.

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 SI80BX1000 Is Used
Long-Stroke Material Transfer
Drives heavy pallets across 1000mm gaps in packaging lines, utilizing the 2513N push force at 0.5MPa to overcome friction.
Corrosive Environment Actuation
Actuates gating and diverter arms in washdown zones using the SUS304 stainless piston rod for rust prevention.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX1000 with the SAI80BX1000
To replace the discontinued SI80BX1000, order the SAI80BX1000. Verify your ISO 15552 mounting hardware (LB, FA, CA, TC), the G3/8 air port, and the M20x1.5 rod thread. Because this is a -B stainless rod variant without a -S magnet, it cannot support legacy CS1-B/DS1-B sensors. If sensing is required, switch to an SAI80X1000S equivalent. For sizing alternatives, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore yields 3927N. At 1000mm stroke, prevent rod bending and premature seal wear by using an external guide to absorb side loads. The standard cushion only decelerates the piston; for secure load holding during air loss, specify the SAIL air-released lock or BSAI clamp-lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX1000
- ✓ 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 SI80BX1000 FAQ
Yes, the SI80BX1000 is discontinued. The direct replacement is the SAI80BX1000. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 1000mm stroke, G3/8 port, and mounting interface. You simply order the SAI80BX1000 to fit existing fixtures.
The 80mm bore uses a G3/8 air port. At 0.5MPa it provides 2513N push and 2268N pull. At 0.7MPa push is 3518N, and at 0.9MPa push is 4523N. The theoretical maximum force is 513kgf at 1.0MPa. Operating speed is 30-800mm/s.
