This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X60, 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 SI80X60
The AirTAC SI80 Standard Air Cylinder SI80X60 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 SAI80X60, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X60
The AirTAC SI80X60 is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 60 mm stroke, delivering 2513 N push and 2268 N pull at 0.5 MPa. AirTAC replaced it with the SAI80X60, a direct replacement sharing the same ISO 15552 mounting interface, G3/8 port, M20x1.5 rod thread and 36 mm cushions. The SAI features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life.
Without a magnet (-S), this SKU cannot accept a sensor, unlike legacy CS1-B/DS1-B equipped variants. The SAI family also adds SAIL, SAIF and BSAI lock variants the SI lacked.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI80X60 carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI80X60 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 SI80X60 Is Used
Mid-Tonnage Pressing
Ideal for applying 2513 N of clamping force at 0.5 MPa to seat bearings or assemble housings in automated cells.
Package Diversion
Drives heavy-duty pusher arms at 30-800 mm/s to redirect totes or pallets on a main conveyor line.
Pallet Stops
Acts as a robust pneumatic stop gate for heavy pallets, using its 36 mm adjustable cushions to absorb end-of-stroke impact.
Replacing the Airtac SI80 Standard Air Cylinder SI80X60 with the SAI80X60
To replace the SI80X60, order the SAI80X60 and confirm the ISO 15552 mounting accessory (LB, FA, TC, etc.), G3/8 port thread (PT/G/NPT) and 60 mm stroke. This non-magnetic SKU cannot take a switch; if sensing is needed, specify an SAI80X60S. Sizing both ways: an 80 mm bore yields 2513 N push at 0.5 MPa, while a neighbouring 63 mm bore offers 1559 N. A plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for held loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X60
- ✓ 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 SI80X60 FAQ
Yes, the AirTAC SI80X60 is discontinued. The direct replacement is the SAI80X60. It shares the same ISO 15552 mounting interface, 80 mm bore, 60 mm stroke, G3/8 port and output force, fitting existing fixtures perfectly.
The 80 mm bore uses a G3/8 air port. Force output is 2513 N push and 2268 N pull at 0.5 MPa, 3518 N push at 0.7 MPa, and a theoretical maximum of 513 kgf at 1.0 MPa.
