This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X360SH, 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 SI160X360SH
The AirTAC SI160 Standard Cylinder SI160X360SH 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 SAI160X360SH, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X360SH
The AirTAC SI160X360SH is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 360 mm stroke. It delivers a push force of 10053 N at 0.5 MPa and features a G3/4 air port, a 40 mm piston rod, and adjustable 50 mm air cushions at both ends. The direct production replacement is the SAI160X360SH, which shares the exact ISO 15552 mounting interface, bore, stroke, output force, and porting to fit existing fixtures seamlessly.
The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure and extended life. This SI unit includes a piston magnet for legacy CS1-B/DS1-B sensors and a Viton H seal rated for 0-150 C. Note that plain cylinders drift without live air; for load holding, use the SAIL lock or BSAI clamp-lock variants.

Theoretical Output Force (Ø160mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10053 N | 9425 N |
| 0.7 MPa | 14074 N | — |

Where the Airtac SI160 Standard Cylinder SI160X360SH Is Used
Heavy Machinery Forming
Drives large presses and forming fixtures where the 14074 N push at 0.7 MPa is required to shape or bend thick metal components.
High-Temp Actuation
Actuates gates or heavy doors near ovens and kilns, leveraging the Viton H seal to withstand 0-150 C ambient heat.
Replacing the Airtac SI160 Standard Cylinder SI160X360SH with the SAI160X360SH
To replace the SI160X360SH, order the SAI160X360SH. Confirm the ISO 15552 mounting interface, the 360 mm stroke, the G3/4 port, and your mounting accessory (LB, FA, TC, etc.). The -S magnet enables current AirTAC switches, while the -H Viton seal handles 0-150 C environments. If downsizing, a 125 mm bore yields 6136 N push at 0.5 MPa; if upsizing, a 200 mm bore provides 15708 N. Because this is a 360 mm stroke, prevent rod bending by supporting the load with external guides to manage side loads. A plain cylinder does not hold load on air loss; for dead-stop holding, specify the SAIL air-released lock, the BSAI clamp-lock, or an external pilot check valve.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X360SH
- ✓ 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 SI160X360SH FAQ
Yes, the SI160X360SH is discontinued. The direct replacement is the SAI160X360SH. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 360 mm stroke, G3/4 port, and mounting interface, so it drops directly into existing fixtures.
This double-acting cylinder has a G3/4 air port. It generates a push force of 10053 N and a pull force of 9425 N at 0.5 MPa. At 0.7 MPa the push is 14074 N, and at 0.9 MPa it is 18095 N. The theoretical maximum force is 2050 kgf at 1.0 MPa.
