This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX190S, 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 SI80AX190S
The AirTAC SI80 Standard Air Cylinder SI80AX190S 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 SAI80AX190S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX190S
The AirTAC SI80AX190S is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore, 190 mm stroke, and a SUS420J2 stainless steel rod. Generating 2513 N push force at 0.5 MPa, it is replaced direct by the SAI80AX190S. The SAI retains the G3/8 port, M20x1.5 thread, and 36 mm cushions, fitting existing fixtures perfectly.
The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure and long life. The -S magnet works with legacy CS1-B/DS1-B sensors, while the SAI family adds SAIL, SAIF, and 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 SI80AX190S Is Used
Mid-Tonnage Pressing
Applies 2513 N of push force at 0.5 MPa for seating bearings, stamping light sheet metal, or clinching components in automated machining cells.
Heavy Package Diversion
Drives robust sorting arms or pushers on high-throughput packaging lines, utilizing the 190 mm stroke to clear wide conveyor belts efficiently.
Pallet Stopper Gates
Acts as a high-force stop or lift gate in pallet handling systems, where the SUS420J2 stainless rod resists humidity and environmental wear.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX190S with the SAI80AX190S
To replace the SI80AX190S, order the SAI80AX190S. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 190 mm stroke, G3/8 port, and mounting accessories. Retain the -A SUS420J2 rod and -S magnet (using current AirTAC switches). If sizing alternatives, neighbouring bores (63 mm or 100 mm) offer 1559 N or 3927 N push at 0.5 MPa. Note that a plain cylinder drifts on air loss; for load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant. The 190 mm stroke is under the 300 mm side-load threshold, but always guide the rod to prevent bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX190S
- ✓ 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 SI80AX190S FAQ
Yes, the SI80AX190S is discontinued. The direct replacement is the SAI80AX190S. It shares the same ISO 15552 mounting interface, 80 mm bore, 190 mm stroke, output force, G3/8 port, and accessories, dropping directly into existing machinery.
The bore is 80 mm with a G3/8 air 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 maximum theoretical force of 513 kgf at 1.0 MPa.
