About the Airtac SAI200 Standard Cylinder SAI200AX165
The AirTAC SAI200X165 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial push force of 15708 N at 0.5 MPa, making it well-suited for demanding industrial tasks requiring immense thrust over a 165 mm stroke. The extruded aluminum barrel design ensures a lightweight yet robust structure.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in harsh environments. It utilizes PT tapered port threads and lacks a magnet. For operations requiring end-position holding without continuous air pressure, the SAIL variant or an external rod lock mechanism must be integrated.

Where the Airtac SAI200 Standard Cylinder SAI200AX165 Is Used
Heavy Metal Stamping
Provides the immense 15708 N push force required to form and stamp thick metal sheets in automated fabrication lines.
Large Mold Clamping
Secures oversized injection molds and heavy industrial tooling securely in place during high-pressure manufacturing cycles.
Massive Load Ejection
Pushes heavy finished parts or dense material blocks out of large-scale CNC machining centers reliably.
Is the Airtac SAI200 Standard Cylinder SAI200AX165 the Right Cylinder?
Selecting this 200 mm bore unit provides maximum thrust within the SAI range; stepping down to a 160 mm bore reduces the push force to 10053 N at 0.5 MPa. Because the stroke is 165 mm, side-load stress on the rod bearing is moderate but manageable. For applications involving heavy lateral loads, pair this cylinder with an external guide rail to prevent premature wear. As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 cylinders, utilizing a G3/4 port, PT threads, and standard mounting accessories like TC trunnions or FA flanges.
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 SAI200 Standard Cylinder SAI200AX165 FAQ
At 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N.
No, the standard SAI200X165 cannot hold a load without live air pressure. For fail-safe load holding, use the SAIL variant with an air-released lock or an external rod lock.
