This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX110, 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 SI80AX110
The AirTAC SI80 Standard Air Cylinder SI80AX110 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 110mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX110, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX110
The AirTAC SI80AX110 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 110 mm stroke, delivering 2513 N of push force at 0.5 MPa. It features a SUS420J2 stainless piston rod for corrosion resistance. Because this legacy unit lacks a magnet, it cannot accept position switches. The direct replacement is the current-production SAI80AX110, which matches the G3/8 port, M20x1.5 thread, and 36 mm cushions exactly.
The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life, while retaining the exact ISO 15552 mounting interface. If your fixture requires load holding on air loss, note that the standard cushion only decelerates; you will need the SAIL or BSAI lock variants.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2513 N | 2268 N |
| 0.7 MPa | 3519 N | — |
| Max (@1.0 MPa) | 513 kgf | |
The SAI80AX110 produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI80 Standard Air Cylinder SI80AX110 Is Used
Corrosive Material Clamping
Leverages the SUS420J2 stainless rod to clamp parts in wash-down or mildly corrosive environments, providing 2513 N of secure holding force at 0.5 MPa.
Package Diverting
Uses the 110 mm stroke to push heavy cartons off a main conveyor line, relying on the adjustable 36 mm air cushions to decelerate the 25 mm rod smoothly.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX110 with the SAI80AX110
To replace the discontinued SI80AX110, order the SAI80AX110. It is a direct per the ISO 15552 mounting interface, preserving the 80 mm bore, 110 mm stroke, G3/8 port, and M20x1.5 rod thread. When sizing, verify your operating pressure: at 0.5 MPa you get 2513 N push and 2268 N pull, while stepping up to 0.7 MPa yields 3518 N of push force. If you need less force, a 63 mm bore provides 1559 N at 0.5 MPa. Because this specific SKU has no magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI variant if position feedback is required. Finally, remember that a standard cylinder drifts without live air—for suspended loads, consider the SAIL air-released lock, the BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX110
- ✓ 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 SI80AX110 FAQ
Yes, the SI80AX110 is discontinued. The direct replacement is the AirTAC SAI80AX110. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 110 mm stroke, G3/8 port, and mounting interface, so it fits existing fixtures perfectly.
This double-acting cylinder features a G3/8 air port and an M20x1.5 rod thread. It delivers 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.
