This model is discontinued
AirTAC has phased out the SI series. You can still order this code here: we ship the direct replacement SAI160BX900, 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 SI160BX900
The AirTAC SI160 Standard Cylinder SI160BX900 is a double-acting ISO 15552 (orig. ISO 6431) profile-barrel cylinder with a Ø160mm bore and 900mm stroke, G3/4 air ports and adjustable end cushioning. This model is discontinued — the direct replacement is the SAI160BX900, which matches its ISO interface, bore, stroke, force and mounting.

About the Airtac SI160 Standard Cylinder SI160BX900
The AirTAC SI160BX900 is a discontinued double-acting ISO 15552 profile cylinder featuring a 160mm bore and 900mm stroke. Delivering 10053 N of thrust at 0.5 MPa via a G3/4 port, it is superseded by the SAI160BX900 direct replacement. This upgrade retains identical ISO 15552 mounting dimensions, output force, and stroke, fitting existing fixtures perfectly.
The SAI160BX900 introduces an upgraded piston seal with two Y-shaped one-way elements for lower start-up pressure and longer life. This specific SKU uses a SUS304 stainless steel rod (option B) for corrosion resistance but lacks a magnet, meaning it cannot accept position switches. For load holding, note that standard cylinders drift on air loss—the cushion only decelerates—so use an external rod lock or pilot check valve.

Where the Airtac SI160 Standard Cylinder SI160BX900 Is Used
Heavy Press Systems
Drives large platens in hydraulic-free pneumatic presses, utilizing 10053 N of push force at 0.5 MPa for forming and stamping heavy assemblies.
Large Mold Handling
Indexes heavy injection molds on production lines, relying on the corrosion-resistant SUS304 rod in humid or washdown manufacturing environments.
Replacing the Airtac SI160 Standard Cylinder SI160BX900 with the SAI160BX900
To replace the discontinued SI160BX900, order the SAI160BX900, ensuring the ISO 15552 mounting interface, 160mm bore, 900mm stroke, G3/4 port, and SUS304 rod option match your fixture. Because this is a 900mm stroke, prevent rod bending and side-load damage by using external guides to support the load. If you need higher force, the 200mm bore offers 15708 N at 0.5 MPa; if less force is acceptable, the 125mm bore provides 6136 N. This non-magnetic SKU cannot support sensors. For applications requiring locked positions without live air, select the SAIL or BSAI lock variants instead of relying on the cushion.
Replacement checklist
- ✓ Same ISO 15552 interface → SAI160BX900
- ✓ 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 SI160BX900 FAQ
Yes, the SI160BX900 is discontinued. The direct replacement is the SAI160BX900. It shares the same ISO 15552 mounting interface, 160mm bore, 900mm stroke, output force, and G3/4 port, fitting directly into your existing fixtures.
At 0.5 MPa, push force is 10053 N and pull is 9425 N. At 0.7 MPa it pushes 14074 N, and 18095 N at 0.9 MPa. The theoretical max force is 2050 kgf at 1.0 MPa. Operating speed is 30-500 mm/s, and the air cushion travel is 50 mm at each end.
