This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X1300S, 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 SI160X1300S
The AirTAC SI160 Standard Cylinder SI160X1300S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 1300mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X1300S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X1300S
The AirTAC SI160X1300S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 1300 mm stroke. It delivers 10053 N push force at 0.5 MPa, using a G3/4 port and M36x2 rod thread. The direct replacement is the SAI160X1300S, matching the exact ISO 15552 mounting interface, stroke, force, and accessories.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The SAI family also adds SAIL, SAIF, and BSAI lock variants the SI lacked. This -S model has a magnet for CS1-B/DS1-B switches; the SAI uses current AirTAC switches.

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 SAI160X1300S 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 SI160X1300S Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures requiring 10053 N thrust at 0.5 MPa over a 1300 mm travel distance.
Pallet Transfer Units
Shifts heavy loaded pallets in automated distribution hubs where a 512 kg vertical lift margin is needed.
Large Door Actuation
Opens and closes substantial industrial blast doors or safety gates using the 160 mm bore power class.
Replacing the Airtac SI160 Standard Cylinder SI160X1300S with the SAI160X1300S
To replace the SI160X1300S, order the SAI160X1300S. Confirm the ISO 15552 mounting interface, 160 mm bore, 1300 mm stroke, G3/4 port, and mounting accessory. The -S magnet equates to legacy CS1-B/DS1-B sensors, while the SAI takes current AirTAC switches. For sizing both ways: a 200 mm bore offers higher force, and a 125 mm bore provides 6136 N push at 0.5 MPa. A plain cylinder drifts on air loss, as the 50 mm cushion only decelerates; use the SAIL or BSAI lock variant for load holding. At 1300 mm, prevent rod bending by guiding the load externally.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X1300S
- ✓ 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 SI160X1300S FAQ
Yes, the SI160X1300S is discontinued. The direct replacement is the SAI160X1300S. It shares the same ISO 15552 mounting interface, 160 mm bore, 1300 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The G3/4 port bore delivers 10053 N push and 9425 N pull at 0.5 MPa, 14074 N push at 0.7 MPa, and a 2050 kgf max at 1.0 MPa. Operating pressure is 0.15-1.0 MPa, with a 50 mm cushion and 30-500 mm/s speed.
