About the Airtac SAI160 Standard Cylinder SAI160AX425
The AirTAC SAI160X425 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a robust push force of 14074 N at 0.7 MPa, making it well-suited for high-mass lifting and pressing over its 425 mm stroke. The extruded aluminum barrel omits tie rods while maintaining strict ISO mounting dimensions.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid industrial environments. It uses PT (tapered) G3/4 ports and lacks a magnet (-S not specified), meaning it is optimized for pure pneumatic actuation without internal magnetic sensing.

Where the Airtac SAI160 Standard Cylinder SAI160AX425 Is Used
Heavy-Duty Stamping
Supplies the 14074 N push force at 0.7 MPa required to form thick metal sheets and operate large mechanical presses.
Automated Plastic Injection
Drives the heavy mold-opening and closing mechanisms on large injection molding machines with precise 425 mm travel.
Bulk Material Diverter
Actuates large heavy-duty gates on mining or aggregate conveyor lines to redirect dense, high-volume bulk materials.
Is the Airtac SAI160 Standard Cylinder SAI160AX425 the Right Cylinder?
With a 425 mm stroke, this 160 mm bore cylinder generates significant side-load risks if the rod bearing bends under heavy off-center loads. To prevent premature seal wear and rod distortion, use an external guide rail or a dedicated guided cylinder to absorb lateral forces. If an application requires less force, stepping down to the 125 mm bore yields 8590 N at 0.7 MPa.
This model is dimensionally interchangeable with other ISO 15552 cylinders, offering a direct replacement solution. Key matching parameters include the 160 mm bore, 425 mm stroke, PT G3/4 port, and standard mounting accessories like FA flange or TC trunnion. Note that this standard cylinder does not hold its position when air pressure is lost; for fail-safe load holding, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants.
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 SAI160AX425 FAQ
The SAI160X425 cylinder provides a push force of 10053 N at 0.5 MPa, 14074 N at 0.7 MPa, and 18095 N at 0.9 MPa. The theoretical maximum force at 1.0 MPa is 2050 kgf.
Yes, the SAI160X425 is a true ISO 15552 profile cylinder. Its standardized mounting interface and dimensions make it a direct replacement for other ISO 15552 cylinders, provided you match the 160 mm bore, 425 mm stroke, and PT G3/4 port.
