This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160AX110, 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 SI160AX110
The AirTAC Airtac SI160 Standard Cylinder SI160AX110 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 110mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160AX110, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160AX110
The AirTAC SI160AX110 is a discontinued double-acting ISO 15552 profile cylinder with a 160 mm bore and 110 mm stroke. It delivers 10053 N push force at 0.5 MPa through a G3/4 port. AirTAC replaced this legacy unit with the SAI160AX110, a direct upgrade retaining the exact interface, stroke and output force.
This SKU features a SUS420J2 stainless steel rod (option A) but lacks a magnet, so it cannot accept position sensors. The SAI upgrade introduces a two Y-shaped one-way piston seal for low start-up pressure.

Where the Airtac SI160 Standard Cylinder SI160AX110 Is Used
Heavy Press Operations
Drives large stamping and forming presses requiring up to 14074 N of thrust at 0.7 MPa, utilizing the 50 mm adjustable cushion to absorb massive kinetic energy at stroke end.
Automated Assembly Lines
Actuates heavy industrial fixtures and large payload shifts where the SUS420J2 stainless rod provides necessary corrosion resistance in harsh manufacturing environments.
Replacing the Airtac SI160 Standard Cylinder SI160AX110 with the SAI160AX110
To replace the SI160AX110, order the SAI160AX110. Confirm the ISO 15552 mounting fixture, 110 mm stroke, G3/4 port and M36x2 rod thread. Because this SKU has no magnet (-S), it cannot support legacy CS1-B/DS1-B sensors; order a magnet-equipped SAI if switching is needed. For sizing, the 125 mm bore offers 6136 N at 0.5 MPa, while the 200 mm bore provides 15708 N. Note that a plain cylinder drifts on air loss—the cushion only decelerates. For load holding, specify an external pilot check valve or the SAIL/BSAI lock variants.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160AX110
- ✓ 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 SI160AX110 FAQ
Yes, the SI160AX110 is discontinued. The direct replacement is the SAI160AX110. It is dimensionally interchangeable per ISO 15552, matching the 160 mm bore, 110 mm stroke, G3/4 port and mounting interface, so it drops directly into existing fixtures.
This double-acting cylinder operates at 30-500 mm/s. It generates 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.
