This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX175S, 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 SI160AX175S
The AirTAC SI160 Standard Cylinder SI160AX175S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 175mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX175S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX175S
The AirTAC SI160AX175S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 175 mm stroke. It delivers a robust 10053 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160AX175S, a direct upgrade retaining the exact same ISO 15552 mounting interface, stroke, output force, and porting to fit existing fixtures seamlessly.
The SAI replacement features an upgraded piston seal with two Y-shaped one-way elements for low start-up pressure and long life. This specific SI160AX175S variant includes an SUS420J2 stainless steel rod (-A) and a piston magnet (-S) for legacy CS1-B/DS1-B sensors.

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 SI160AX175S Is Used
Heavy Press Clamping
Ideal for exerting massive steady pressure on large metal stamping or forming dies, utilizing the 10053 N push force at 0.5 MPa.
Industrial Mold Handling
Shifts substantial injection mold bases or heavy industrial tooling securely, aided by the SUS420J2 stainless rod option.
Replacing the Airtac SI160 Standard Cylinder SI160AX175S with the SAI160AX175S
To replace the discontinued SI160AX175S, order the SAI160AX175S. Confirm the ISO 15552 mounting interface, 175 mm stroke, G3/4 port, and your specific mounting accessory (LB, FA, TC, etc.). The -S magnet enables CS1-B/DS1-B switches (the SAI uses current AirTAC sensors), and the -A rod denotes the SUS420J2 stainless material. When sizing, the 160 mm bore yields 10053 N push at 0.5 MPa; dropping to a 125 mm bore gives 6136 N, while staying at 160 mm but increasing to 0.7 MPa provides 14074 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates—so use an external rod lock, pilot check valve, or the SAIL/BSAI lock variant for load holding. For this 175 mm stroke, ensure guide alignment to prevent rod bending and side-load wear.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX175S
- ✓ 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 SI160AX175S FAQ
Yes, the AirTAC SI160AX175S is discontinued. The direct replacement is the SAI160AX175S. It shares the identical ISO 15552 mounting interface, 160 mm bore, 175 mm stroke, output force, and G3/4 port, fitting existing fixtures perfectly.
The 160 mm bore cylinder operates at 30-500 mm/s. 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.
