This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80AX60, 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 SI80AX60
The AirTAC SI80 Standard Air Cylinder SI80AX60 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø80mm bore and 60mm stroke, G3/8 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI80AX60, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80AX60
The AirTAC SI80AX60 is a discontinued double-acting ISO 15552 profile cylinder with an 80mm bore and 60mm stroke. It delivers 2513N push and 2268N pull at 0.5MPa via a G3/8 port. The direct replacement is the SAI80AX60, matching the interface, force, and mounting.
This SKU features a SUS420J2 stainless rod but lacks a magnet, so it cannot accept a sensor. The SAI upgrade uses two Y-shaped piston seals for low start-up pressure. For load holding, use 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 | — |

Where the Airtac SI80 Standard Air Cylinder SI80AX60 Is Used
Short-Stroke Clamping
Ideal for high-force 60mm clamping tasks in machining fixtures where the SUS420J2 stainless rod resists coolant corrosion.
Transfer Diverters
Provides robust actuation for heavy package diverters on conveyor lines, utilizing the 2513N thrust at 0.5MPa.
Pallet Stops
Acts as a heavy-duty pneumatic stop for palletized goods, handling dynamic impacts without relying on a holding lock.
Replacing the Airtac SI80 Standard Air Cylinder SI80AX60 with the SAI80AX60
To replace the SI80AX60, order the SAI80AX60 to retain the exact ISO 15552 mounting interface, 80mm bore, 60mm stroke, and G3/8 port. Confirm your rod material needs: this -A code specifies a SUS420J2 stainless rod, unlike the standard carbon steel. Since this SKU lacks the -S magnet suffix, it cannot support position sensing; if switches are needed, specify a magnet on the SAI order. For sizing alternatives, a 63mm bore yields 1559N push at 0.5MPa, while a 100mm bore provides 3927N. Remember that a standard cylinder drifts without live air; for held loads, select the SAIL or BSAI lock variant, or add an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80AX60
- ✓ 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 SI80AX60 FAQ
Yes, the AirTAC SI80AX60 is discontinued. The direct replacement is the SAI80AX60. It is dimensionally interchangeable per ISO 15552, retaining the same 80mm bore, 60mm stroke, G3/8 port, and mounting interface.
This double-acting cylinder 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 theoretical max of 513kgf at 1.0MPa.
