This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80BX95, 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 SI80BX95
The AirTAC SI80 Standard Air Cylinder SI80BX95 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 95mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80BX95, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80BX95
The AirTAC SI80BX95 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore, 95 mm stroke, and a SUS304 stainless steel rod. It delivers 2513 N push force at 0.5 MPa. The direct replacement is the SAI80BX95, matching the exact ISO 15552 mounting interface, bore, stroke, force, and G3/8 port. The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life.
Because this SKU lacks the -S magnet, it cannot accept a CS1-B or DS1-B sensor. For load holding, note that the air cushion only decelerates; a plain cylinder drifts without live air, so use an external rod lock or pilot check valve.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80BX95 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SI80BX95 Is Used
Washdown Clamping
Secures parts in food or chemical processing lines where the SUS304 rod resists moisture and corrosion.
Package Diverting
Actuates routing gates on high-speed packaging conveyors using its 2513 N thrust at 0.5 MPa.
Pallet Stopping
Controls heavy pallet flow on roller tracks by absorbing kinetic energy with its 36 mm adjustable cushions.
Replacing the Airtac SI80 Standard Air Cylinder SI80BX95 with the SAI80BX95
To replace the discontinued SI80BX95, order the SAI80BX95. Verify the ISO 15552 mounting interface, 80 mm bore, 95 mm stroke, G3/8 port, and M20x1.5 rod thread. This unit uses a SUS304 stainless rod for corrosion resistance. Since it has no -S suffix, magnetic switches cannot be fitted. For sizing alternatives, a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore provides 3927 N. If you need integrated load holding, explore the SAIL or BSAI lock variants, or the SAIF self-valve option.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80BX95
- ✓ 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 SI80BX95 FAQ
Yes, the SI80BX95 is discontinued. The direct replacement is the SAI80BX95. It is dimensionally interchangeable per ISO 15552, retaining the same 80 mm bore, 95 mm stroke, force, and G3/8 port to fit existing fixtures directly.
It features a G3/8 air port. The 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 maximum theoretical force of 513 kgf at 1.0 MPa.
