This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX10, 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 SI80BX10
The AirTAC SI80 Standard Air Cylinder SI80BX10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 10mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX10
The AirTAC SI80BX10 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 10 mm stroke. It features a SUS304 stainless piston rod and delivers 2513 N push force at 0.5 MPa. The direct replacement is the SAI80BX10, retaining the exact G3/8 port, M20x1.5 thread and ISO 15552 mounting interface.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and long life. Because this specific SI80BX10 SKU lacks a magnet, it cannot accept a position switch.

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 SI80BX10 Is Used
Short-Stroke Clamping
Ideal for holding stainless workpieces in machining fixtures where the 10 mm stroke and SUS304 rod resist coolant corrosion.
Gate Diversion
Provides robust 2513 N push force at 0.5 MPa to deflect heavy packages on a high-speed packaging line.
Pallet Stopper
Acts as a high-force end-stop for inbound pallets, utilizing the 80 mm bore to halt loads safely without needing full stroke extension.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX10 with the SAI80BX10
To replace the discontinued SI80BX10, order the SAI80BX10. Confirm the ISO 15552 mounting interface, 80 mm bore, 10 mm stroke, G3/8 port (PT/G/NPT thread options) and your mounting accessory. This SKU has no magnet (-S), so it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if sensing is required. The SUS304 rod suits corrosive environments. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding. For higher force, the 100 mm bore offers 3927 N push at 0.5 MPa; for less, the 63 mm bore provides 1559 N.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX10
- ✓ 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 SI80BX10 FAQ
Yes, the AirTAC SI80BX10 is discontinued. The direct replacement is the SAI80BX10. It is dimensionally interchangeable per ISO 15552, maintaining the same 80 mm bore, 10 mm stroke, 4523 N output force, G3/8 port and mounting interface.
The 80 mm bore uses a G3/8 port. Force output is 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.
