This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X160, 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 SI160X160
The AirTAC SI160 Standard Cylinder SI160X160 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 160mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X160, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X160
The AirTAC SI160X160 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 160 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. The direct replacement is the SAI160X160, retaining the exact ISO 15552 mounting interface, M36x2 rod thread, and 50 mm cushions.
This SKU lacks a magnet and cannot accept a sensor. The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure, and introduces SAIL and BSAI lock variants absent in 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 SAI160X160 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 SI160X160 Is Used
Heavy Press Forming
Generates 14074 N at 0.7 MPa to seat large bearings or form thick metal panels in automated stamping lines.
Mold Clamping
Secures heavy injection molds via the ISO 15552 mounting interface, providing rigid 18095 N clamping at 0.9 MPa.
Replacing the Airtac SI160 Standard Cylinder SI160X160 with the SAI160X160
To replace the SI160X160, order the SAI160X160 and verify your ISO 15552 interface, G3/4 port, and M36x2 rod thread. Because this specific SKU has no -S suffix, it cannot support magnetic sensing; choose an SAI160X160S if position detection is needed. Sizing both ways: a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external pilot check valve or the SAIL/BSAI lock variant for load holding. Operating speed is 30-500 mm/s.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X160
- ✓ 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 SI160X160 FAQ
Yes, the SI160X160 is discontinued. The direct replacement is the SAI160X160. It shares the same ISO 15552 mounting interface, 160 mm bore, 160 mm stroke, force, and G3/4 port, fitting existing fixtures perfectly.
It features a G3/4 port. 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, and a theoretical maximum of 2050 kgf at 1.0 MPa.
