This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X10, 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 SI80X10
The AirTAC SI80 Standard Air Cylinder SI80X10 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 10mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80X10, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X10
The AirTAC SI80X10 is a discontinued double-acting ISO 15552 profile cylinder with a 10 mm stroke, delivering 2513 N push force at 0.5 MPa. AirTAC replaced it with the SAI80X10, a direct upgrade sharing the exact same 80 mm bore, G3/8 port, and mounting interface.
The SAI upgrade features a modernized piston seal with two Y-shaped one-way elements for low start-up pressure and long life. Because this specific SKU lacks a magnet (-S), it cannot accept a CS1-B/DS1-B sensor.

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 SAI80X10 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 SI80X10 Is Used
Short-Stroke Clamping
Ideal for holding heavy metal castings in CNC machining fixtures where a brief 10 mm travel applies 2513 N of secure clamping force.
Compact Pressing
Performs spot welding or riveting tasks in confined assembly cells, using its 80 mm bore to deliver high impact force over a very short distance.
Heavy Ejector
Serves as a robust parts ejector at the end of material handling lines, rapidly pushing 128 kg workpieces off the belt without occupying much length.
Replacing the Airtac SI80 Standard Air Cylinder SI80X10 with the SAI80X10
To replace the discontinued SI80X10, order the SAI80X10. Confirm your ISO 15552 mounting accessory (LB, FA, TC, etc.), the G3/8 port thread (PT/G/NPT), and the M20x1.5 rod thread. Since this SKU has no magnet, you cannot mount position sensors; if sensing is required, order the SAI80X10S instead. If you need more force than the 2513 N at 0.5 MPa, step up to a 100 mm bore; if less is needed, a 63 mm bore provides 1559 N. For load holding on air loss, note that the air cushion only decelerates the piston and does not lock it—you will need an external pilot check valve or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X10
- ✓ 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 SI80X10 FAQ
Yes, the SI80X10 is discontinued. The direct replacement is the SAI80X10. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 10 mm stroke, 2513 N force, G3/8 port, and mounting interface.
This double-acting cylinder has a G3/8 air port. 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 force of 513 kgf at 1.0 MPa.
