This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX1000, 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 SI80AX1000
The AirTAC SI80 Standard Air Cylinder SI80AX1000 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 1000mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX1000, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX1000
The AirTAC SI80AX1000 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 1000mm stroke. It delivers 2513N push force at 0.5MPa via a G3/8 port. Because this legacy unit is end-of-life, AirTAC specifies the SAI80AX1000 as the direct successor, matching the ISO 15552 mounting interface, M20x1.5 rod thread, and 36mm cushions.
The SAI upgrade introduces a two-piece Y-shaped piston seal for lower start-up pressure and longer life. This specific SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. The SUS420J2 stainless rod (A) resists corrosion. Note that plain cylinders drift without air; use a SAIL lock or pilot check valve to hold loads.

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 SAI80AX1000 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 SI80AX1000 Is Used
Long-Stroke Material Transfer
Pushes heavy pallets 1000mm between conveyor lines using 2513N force, requiring external guides to prevent rod bending over the extended length.
Corrosive Washdown Actuation
Actuates tooling in humid washdown zones using the SUS420J2 stainless rod option, while the Viton H seal handles higher temperatures.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX1000 with the SAI80AX1000
To replace the discontinued SI80AX1000, order the SAI80AX1000. Verify your ISO 15552 mounting accessories (LB, FA, TC, etc.), the G3/8 port, and the 1000mm stroke. Because this SKU has no magnet, you cannot mount position sensors; if sensing is needed, switch to an SAI80X1000S. For sizing down, a 63mm bore yields 1559N push at 0.5MPa; sizing up to 100mm provides 3927N. Remember, the air cushion only decelerates near stroke end—it does not hold load. For load holding on air loss, use the SAIL air-released lock, the BSAI clamp-lock, or an external pilot check valve. At 1000mm, prevent rod bending by guiding the load externally to avoid side-load damage.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX1000
- ✓ 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 SI80AX1000 FAQ
Yes, the SI80AX1000 is discontinued. The direct replacement is the SAI80AX1000. It shares the same ISO 15552 mounting interface, 80mm bore, 1000mm stroke, output force, G3/8 port, and M20x1.5 rod thread, fitting directly into existing fixtures.
The 80mm bore uses a G3/8 port. It generates 2513N push and 2268N pull at 0.5MPa, 3518N push at 0.7MPa, 4523N push at 0.9MPa, and a maximum theoretical force of 513kgf at 1.0MPa. Operating speed is 30-800mm/s.
