This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X360, 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 SI160X360
The AirTAC SI160 Standard Cylinder SI160X360 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 360mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X360, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X360
The AirTAC SI160X360 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 360 mm stroke. Delivering 10053 N push force at 0.5 MPa, it features a 40 mm rod, M36x2 thread, and a G3/4 port. The direct replacement is the SAI160X360, which matches the exact ISO 15552 mounting interface, bore, stroke, output force, and port size for seamless fixture integration.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. Note this specific SKU lacks a magnet (-S), so it cannot accept CS1-B/DS1-B sensors. If higher temperatures are needed, Viton H seals raise the range to 0-150 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 SAI160X360 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 SI160X360 Is Used
Heavy Press Clamping
Generates 14074 N at 0.7 MPa to secure large metal castings during machining operations.
Large Mold Ejection
Drives heavy injection molds out of the press using the 40 mm rod over a 360 mm travel.
Replacing the Airtac SI160 Standard Cylinder SI160X360 with the SAI160X360
To replace the SI160X360, order the SAI160X360 ensuring the ISO 15552 mounting interface, 360 mm stroke, G3/4 port, and accessory type (LB, FA, TC, etc.) match. Because this SKU has no -S suffix, it cannot support magnetic sensing. For sizing, a 125 mm bore yields 6136 N push at 0.5 MPa, while a 200 mm bore yields 15708 N. At 360 mm stroke, use external guides to prevent rod bending and side-load wear. The air cushion only decelerates; it does not hold load. For dead-load holding on air loss, specify an external pilot check valve, rod lock, or the SAIL/BSAI lock variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X360
- ✓ 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 SI160X360 FAQ
Yes, the SI160X360 is discontinued. The direct replacement is the SAI160X360, which shares the same ISO 15552 mounting interface, 160 mm bore, 360 mm stroke, force, and G3/4 port.
At 0.5 MPa it pushes 10053 N and pulls 9425 N. At 0.7 MPa it pushes 14074 N, and at 0.9 MPa it pushes 18095 N. The theoretical max is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s.
