About the Airtac SAI160 Standard Cylinder SAI160AX450S
The AirTAC SAI160X450-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 14074N of push force at 0.5 MPa, this 160mm bore unit is built to move substantial masses across its 450mm stroke. The extruded aluminum barrel omits traditional tie-rods, presenting a clean profile that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid or washdown environments. Equipped with a magnetic piston (-S), it supports CMSE and DMSE reed switches seated neatly within the dual sensor grooves on the barrel. PT tapered port threads guarantee a robust, leak-free pneumatic connection for high-flow operations.

Where the Airtac SAI160 Standard Cylinder SAI160AX450S Is Used
Heavy Metal Stamping
Provides the high thrust required to actuate large press dies and form thick metal components in automotive production lines.
Pallet Diverting
Shifts heavy pallets laterally across high-throughput packaging conveyors where substantial mass demands robust pushing power.
Large Mold Handling
Positions and extracts heavy injection molds, relying on the durable SUS420J2 rod to withstand industrial plant conditions.
Is the Airtac SAI160 Standard Cylinder SAI160AX450S the Right Cylinder?
Generating 14074N at just 0.5 MPa makes this 160mm bore an excellent choice over the 125mm option (which yields 6136N) when you need to move heavy payloads without maxing out your air pressure. If full force is not required, stepping down to the 125mm bore saves air volume and cost. For this 450mm stroke, side loads are a primary concern; long unsupported rods are prone to bending under lateral stress. Employing an external guide rail or a guided cylinder module is strongly recommended to protect the rod bearing and prevent premature seal wear.
While the adjustable air cushions at both ends effectively decelerate the piston at stroke extremes, they do not function as a mechanical lock. If your application requires the load to be held securely in place during a complete loss of air pressure, you must integrate an external pilot-operated check valve or specify the SAIL (air-released lock) variant. Ensure your mounting setup matches the ISO 15552 interface by utilizing compatible TC trunnion or FA flange accessories.
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 SAI160AX450S FAQ
This 160mm bore cylinder generates 14074N of push force and 9425N of pull force at 0.5 MPa. At the maximum operating pressure of 1.0 MPa, it can deliver a theoretical maximum force of 2050 kgf.
No, the standard SAI cylinder does not hold position without live air pressure, and the adjustable air cushions only decelerate the piston near the stroke ends. For fail-safe load holding, use the SAIL variant with an air-released lock or an external rod lock.
