This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX190, 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 SI80AX190
The AirTAC SI80 Standard Air Cylinder SI80AX190 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 190mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX190, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX190
The AirTAC SI80AX190 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 190mm stroke. Delivering 2513N push force at 0.5MPa via a G3/8 port, it is replaced by the SAI80AX190. This direct successor matches the exact ISO 15552 mounting interface, bore, stroke, output force and port size, fitting existing fixtures perfectly.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SI80AX190 variant uses a SUS420J2 stainless steel rod, but lacks a magnet so it cannot take a sensor. For higher heat, Viton H seals raise the temperature limit 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 SI80AX190 Is Used
Press Fit Assembly
Drives bearings into housings on an automated line, using the 2513N thrust at 0.5MPa to seat heavy components securely.
Pallet Diverting
Actuates heavy-duty diverters on a packaging conveyor, where the 190mm stroke pushes loaded pallets onto a secondary track.
Material Lift Gate
Raises and lowers an 80kg access gate on a storage mezzanine, safely operating within the 128kg vertical lift margin.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX190 with the SAI80AX190
To replace the SI80AX190, order the SAI80AX190. Confirm the ISO 15552 mounting interface, the 80mm bore, 190mm stroke, G3/8 port (PT/G/NPT thread options), and your specific mounting accessory (LB, FA, TC, etc.). Because this SKU lacks the -S magnet, it cannot accept CS1-B/DS1-B switches; order a magnet-equipped SAI if sensing is needed. The SUS420J2 stainless rod provides corrosion resistance versus standard carbon steel. Sizing both ways: the 80mm bore yields 2513N push at 0.5MPa, while a neighbouring 100mm bore offers 3927N. Remember, a plain cylinder drifts on air loss as the cushion only decelerates; for load holding, specify an external pilot check valve, rod lock, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX190
- ✓ 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 SI80AX190 FAQ
Yes, the AirTAC SI80AX190 is discontinued. The direct replacement is the SAI80AX190. It shares the identical ISO 15552 mounting interface, 80mm bore, 190mm stroke, output force, and G3/8 port, fitting your existing fixtures without modification.
The bore is 80mm with a G3/8 air port and an M20x1.5 rod thread. Force ratings are: 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a theoretical maximum of 513kgf at 1.0MPa.
