This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX230, 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 SI80AX230
The AirTAC SI80 Standard Air Cylinder SI80AX230 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX230, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX230
The AirTAC SI80AX230 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 230mm stroke. It delivers 2513 N push and 2268 N pull at 0.5 MPa, utilizing a G3/8 port and an M20x1.5 rod thread. The direct replacement is the SAI80AX230, which maintains the exact same interface, output force, and mounting dimensions.
The SAI upgrade introduces a two Y-shaped one-way piston seal for lower start-up pressure and longer life. This SI80AX230 variant features a SUS420J2 stainless steel rod (-A) for corrosion resistance, but lacks a magnet (-S), meaning it cannot accept position switches.

Where the Airtac SI80 Standard Air Cylinder SI80AX230 Is Used
Mid-Tonnage Pressing
Applies up to 3518 N of push force at 0.7 MPa for seating bearings, stamping light sheet metal, or clinching components in automated assembly lines.
Corrosive Environment Actuation
Leverages the SUS420J2 stainless steel piston rod to push and pull dampers, doors, or diverter gates in washdown areas or humid production zones.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX230 with the SAI80AX230
To replace the SI80AX230, order the SAI80AX230. Confirm the ISO 15552 mounting interface, the 80mm bore, 230mm stroke, G3/8 port (PT/G/NPT thread options), and your specific mounting accessory. Because this SKU lacks the -S magnet, it cannot support legacy CS1-B/DS1-B sensors; if sensing is required, switch to a magnet-equipped SAI. When sizing, the 80mm bore yields 2513 N push at 0.5 MPa; dropping to a 63mm bore reduces push to 1559 N, while an 80mm bore at 0.7 MPa yields 3518 N. Note that a plain cylinder does not hold load without live air—the cushion only decelerates. For load holding, use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. At 230mm stroke, side-load and rod-bending risks are moderate; ensure guide alignment to prevent premature seal wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX230
- ✓ 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 SI80AX230 FAQ
Yes, the AirTAC SI80AX230 is discontinued. The direct replacement is the SAI80AX230. It is dimensionally interchangeable per ISO 15552, matching the 80mm bore, 230mm stroke, G3/8 port, and mounting interface, so it fits existing fixtures perfectly.
The 80mm bore provides a push force of 2513 N and a pull force of 2268 N at 0.5 MPa. At 0.7 MPa it pushes 3518 N, and at 0.9 MPa it pushes 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa. Operating speed ranges from 30-800 mm/s.
