This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X600FA, 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 SI160 Standard Cylinder SI160X600FA
The AirTAC Airtac SI160 Standard Cylinder SI160X600FA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 600mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X600FA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X600FA
The AirTAC SI160X600FA is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 600 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X600FA, retaining the same interface, M36x2 thread, and FA flange mounting.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. Note this non-magnet SKU cannot take a sensor; the SAI family also adds SAIL and BSAI lock variants absent from the SI line.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |
| Max (@1.0 MPa) | 2050 kgf | |
The SAI160X600FA produces the same force from the same bore. Actual usable force is lower than theoretical; size with a margin.

Where the Airtac SI160 Standard Cylinder SI160X600FA Is Used
Heavy Press Forming
Drives large press fixtures requiring substantial thrust, delivering 14074 N at 0.7 MPa to form thick metal components reliably.
Pallet Dispenser
Actuates heavy-duty pallet dispensing gates in automated warehouses, utilizing the 600 mm stroke to push stacked pallets into position.
Replacing the Airtac SI160 Standard Cylinder SI160X600FA with the SAI160X600FA
To replace the SI160X600FA, order the SAI160X600FA direct, verifying the ISO 15552 FA flange interface, 160 mm bore, 600 mm stroke, and G3/4 port. This non-magnet SKU cannot accept a CS1-B/DS1-B sensor. At 0.5 MPa it yields 10053 N push and 9425 N pull; the neighboring 200 mm bore offers 15708 N push if more force is needed. Because the 600 mm stroke invites rod bending, use external guides to prevent side loads. A plain cylinder drifts on air loss; for load holding use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X600FA
- ✓ Same bore / stroke / force
- ✓ Port/thread type (PT/G/NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Mounting reused (FA/FB/CA/CB/CR/LB/TC)
Airtac SI160 Standard Cylinder SI160X600FA FAQ
Yes, the SI160X600FA is discontinued. The direct replacement is the SAI160X600FA. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 600 mm stroke, G3/4 port, and FA flange mount.
It features a G3/4 port and 40 mm rod. Force ratings are: 10053 N push and 9425 N pull at 0.5 MPa; 14074 N push at 0.7 MPa; 18095 N push at 0.9 MPa; with a theoretical max of 2050 kgf at 1.0 MPa.
