This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160X260S, 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 SI160X260S
The AirTAC SI160 Standard Cylinder SI160X260S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 260mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160X260S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160X260S
The AirTAC SI160X260S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 260 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. The direct replacement is the SAI160X260S, matching the exact bore, stroke, force, port and ISO 15552 mounting interface.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. The -S suffix means a built-in piston magnet for legacy CS1-B/DS1-B sensors; the SAI uses current AirTAC switches. For high heat, Viton H seals raise the temperature 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 | — |

Where the Airtac SI160 Standard Cylinder SI160X260S Is Used
Heavy Press Forming
Generates 14074 N at 0.7 MPa to seat bearings and stamp thick metal plates in automated fabrication cells.
Mold Clamping Systems
Holds large injection molds securely in place during processing, utilizing the 160 mm bore profile barrel.
Replacing the Airtac SI160 Standard Cylinder SI160X260S with the SAI160X260S
To replace the SI160X260S, order the SAI160X260S. Verify the ISO 15552 mounting interface, 260 mm stroke, M36x2 rod thread, G3/4 port and the -S magnet. Sizing both ways: a 200 mm bore offers more force, while a 125 mm bore provides 6136 N push at 0.5 MPa. For load holding, note that a plain cylinder drifts on air loss as the cushion only decelerates; use an external rod lock, pilot check valve, or the SAIL/BSAI lock variants. The 40 mm rod and 260 mm stroke resist side-loads well, but always guide the tooling to prevent rod bending.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160X260S
- ✓ 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 SI160X260S FAQ
Yes, the SI160X260S is discontinued. The direct replacement is the AirTAC SAI160X260S. It is dimensionally interchangeable per ISO 15552, retaining the same 160 mm bore, 260 mm stroke, output force, G3/4 port and mounting accessories.
This double-acting cylinder features a G3/4 port and delivers a push force of 10053 N and pull of 9425 N at 0.5 MPa. At 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical maximum force is 2050 kgf at 1.0 MPa.
