This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X980SFA, 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 SI160X980SFA
The AirTAC Airtac SI160 Standard Cylinder SI160X980SFA is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 980mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X980SFA, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X980SFA
The AirTAC SI160X980SFA is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 980 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160X980SFA, a direct replacement sharing the exact ISO 15552 mounting interface, bore, stroke, and force.
The SAI upgrade features a new piston seal with two Y-shaped one-way elements for low start-up pressure and long life. It also adds lock variants (SAIL, BSAI) absent from the SI line. The included magnet supports CS1-B/DS1-B switches, and Viton H seals raise the temperature limit to 150 C.

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 SAI160X980SFA 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 SI160X980SFA Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring high thrust, using the 10053 N push force at 0.5 MPa to shape heavy metal components.
Oversized Part Diversion
Actuates heavy-duty diverter arms over 980 mm strokes on conveyor lines, relying on external guides to prevent rod bending.
Replacing the Airtac SI160 Standard Cylinder SI160X980SFA with the SAI160X980SFA
To replace the SI160X980SFA, order the SAI160X980SFA. Confirm the ISO 15552 FA flange mounting interface, 980 mm stroke, G3/4 port, and the -S magnet for legacy CS1-B/DS1-B sensors. If you need less force, the neighboring 125 mm bore yields 6136 N push at 0.5 MPa; if you need more, the 200 mm bore provides 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates near stroke end—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding. Because 980 mm exceeds 300 mm, use external guides to prevent rod bending and side loads.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X980SFA
- ✓ 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 SI160X980SFA FAQ
Yes, the SI160X980SFA is discontinued. The direct replacement is the SAI160X980SFA. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 980 mm stroke, G3/4 port, and FA flange mounting.
At 0.5 MPa it provides 10053 N push and 9425 N pull. At 0.7 MPa push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical max is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, with a 50 mm adjustable air cushion at both ends.
