This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX95S, 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 SI160AX95S
The AirTAC Airtac SI160 Standard Cylinder SI160AX95S is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 95mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX95S, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX95S
The AirTAC SI160AX95S is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 95 mm stroke. It delivers 10053 N push force at 0.5 MPa via a G3/4 port. AirTAC replaced this legacy unit with the SAI160AX95S, a direct sharing the exact ISO 15552 mounting interface, bore, stroke, force, and accessories.
The SAI upgrade features a two Y-shaped one-way piston seal for low start-up pressure and long life. This SI unit has the SUS420J2 stainless rod option and a piston magnet for CS1-B/DS1-B switches.

Specifications follow the official AirTAC SI datasheet (now discontinued). The SAI160AX95S carries the same ISO 15552 ratings. Confirm against the product label before installation. Thread options: PT / G / NPT.
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 SAI160AX95S 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 SI160AX95S Is Used
Heavy Press Clamping
Generates 14074 N of thrust at 0.7 MPa to secure large metal workpieces in heavy-duty machining and press fixtures.
Automated Assembly Forming
Drives robust 95 mm stroke pressing operations in automated automotive lines, handling high impact loads reliably.
Replacing the Airtac SI160 Standard Cylinder SI160AX95S with the SAI160AX95S
To replace the SI160AX95S, order the SAI160AX95S. Confirm the ISO 15552 mounting interface, 95 mm stroke, G3/4 port, and mounting accessory. The -S magnet enables CS1-B/DS1-B sensors (the SAI uses current AirTAC switches), and the -A code specifies the SUS420J2 stainless rod. Sizing both ways: this bore yields 10053 N push at 0.5 MPa, while a neighbouring 200 mm bore offers 15708 N. For load holding, 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 variant.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX95S
- ✓ 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 SI160AX95S FAQ
Yes, the SI160AX95S is discontinued. The direct replacement is the SAI160AX95S. It is dimensionally interchangeable per the ISO 15552 mounting interface, retaining the same 160 mm bore, 95 mm stroke, 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 force of 9425 N at 0.5 MPa. At 0.7 MPa it pushes 14074 N, and the theoretical maximum force is 2050 kgf at 1.0 MPa.
