About the Airtac SAI160 Standard Cylinder SAI160AX290S
The AirTAC SAI160X290-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 14074 N of push force at 0.7 MPa, this 160 mm bore unit is built to move serious masses. The 290 mm stroke provides ample travel for large-format clamping and heavy press operations.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance and reduced wear in harsh environments. Equipped with a magnet (-S), it supports CMSE and DMSE sensor switches via the dual side grooves on the extruded aluminum barrel. Fluid ports utilize a PT tapered thread design, ensuring robust, leak-free pneumatic connections.

Where the Airtac SAI160 Standard Cylinder SAI160AX290S Is Used
Heavy-Duty Stamping
Provides the 14074 N force necessary for forming and stamping thick metal components in automated fabrication lines.
Large Mold Handling
Utilizes the 290 mm stroke and SUS420J2 rod to safely actuate and shift heavy industrial molds within injection molding facilities.
Automotive Assembly
Drives large-scale robotic welding fixtures and heavy chassis positioning actuators requiring high thrust and PT port reliability.
Is the Airtac SAI160 Standard Cylinder SAI160AX290S the Right Cylinder?
Selecting this 160 mm bore over the smaller 125 mm option upgrades your thrust from 8590 N to 14074 N at 0.7 MPa, a necessary step when overcoming high mechanical friction or moving heavy payloads. If 14074 N exceeds your requirement, dropping to the 125 mm bore saves space and air consumption.
Because the 290 mm stroke generates extended leverage, unsupported side loads can severely stress the rod bearing and cause premature seal failure. Implementing an external guide rail or selecting a guided cylinder variant is strongly recommended to absorb lateral forces. Note that the adjustable air cushions only decelerate the piston near the stroke ends; they do not lock or hold the load. If your application requires dead-stop positioning without live air pressure, integrate the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI160 Standard Cylinder SAI160AX290S FAQ
This 160 mm bore cylinder generates 14074 N of push force and 9425 N of pull force at a 0.7 MPa operating pressure. At 0.5 MPa, it delivers 10053 N push and 9425 N pull.
Yes, the SAI160X290-S is dimensionally interchangeable with other ISO 15552 profile cylinders. You can drop it into existing mounting footprints (like FA flange or TC trunnion) and use PT port connections without redesigning your framework.
