This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI80X60FA, 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 SI80X60FA
The AirTAC SI80 Standard Air Cylinder SI80X60FA 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 SAI80X60FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI80 Standard Air Cylinder SI80X60FA
The AirTAC SI80X60FA is a discontinued double-acting ISO 15552 profile cylinder with an 80 mm bore and 60 mm stroke. It delivers 2513 N push force at 0.5 MPa via a G3/8 port. The direct replacement is the SAI80X60FA, retaining the exact FA flange mounting interface, M20x1.5 rod thread, and 36 mm cushions.
Because this SKU lacks the -S magnet, it cannot accept CS1-B/DS1-B sensors. The SAI upgrade features two Y-shaped one-way piston seals for low start-up pressure. For load holding, note that cushions only decelerate; use an external rod lock or the SAIL/BSAI 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 SAI80X60FA 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 SI80X60FA Is Used
Press Fit Operations
Applies 2513 N of push force at 0.5 MPa to seat bearings and pins reliably in automated machining lines without requiring high-pressure hydraulics.
Flange-Mounted Diverter
Uses the rigid FA flange interface to swing heavy routing gates on packaging conveyors, handling the 60 mm stroke with stable side-load resistance.
Pallet Lift Stops
Acts as a robust physical stop for pallets weighing up to 128 kg in vertical lift zones, safely decelerating moving loads via its 36 mm adjustable cushions.
Replacing the Airtac SI80 Standard Air Cylinder SI80X60FA with the SAI80X60FA
To replace the SI80X60FA, order the SAI80X60FA. Verify the ISO 15552 FA flange interface, 80 mm bore, 60 mm stroke, and G3/8 port. This SKU has no -S magnet, so no position sensing is possible; order an -S variant if switches are needed. Sizing both ways: a 63 mm bore yields 1559 N push at 0.5 MPa, while a 100 mm bore yields 3927 N. A plain cylinder drifts on air loss—the cushion only decelerates—so for holding loads use an external pilot check valve or the SAIL/BSAI lock variants. The SAI family also offers the SAIF integrated valve (bores 32-100).
Replacement checklist
- ✓ Same ISO 15552 interface → SAI80X60FA
- ✓ 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 SI80X60FA FAQ
Yes, the SI80X60FA is discontinued. The direct replacement is the SAI80X60FA. It is dimensionally interchangeable per ISO 15552, matching the 80 mm bore, 60 mm stroke, G3/8 port, and FA flange mount exactly.
It features a G3/8 port and provides 2513 N push and 2268 N pull at 0.5 MPa. At 0.7 MPa push is 3518 N, and at 0.9 MPa it is 4523 N. The theoretical maximum force is 513 kgf at 1.0 MPa.
