About the Airtac SAI200 Standard Cylinder SAI200AX450
The AirTAC SAI200X450 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving massive loads over its 450 mm stroke. The extruded aluminum barrel design eliminates tie-rods, offering a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced resistance against corrosion and surface wear. It utilizes PT tapered port threads, and because it lacks the -S magnet suffix, it is optimized for pure pneumatic actuation without integrated sensor switching.

Where the Airtac SAI200 Standard Cylinder SAI200AX450 Is Used
Heavy Metal Stamping
Provides the robust 15708 N push force required to actuate large mechanical presses and form thick sheet metal components securely.
Large Mold Handling
Shifts heavy injection molds or die sets along the 450 mm stroke, utilizing the SUS420J2 rod to withstand harsh industrial environments.
Bulk Material Diversion
Drives heavy-duty diverter arms on high-capacity aggregate or mining conveyors where massive kinetic energy must be managed reliably.
Is the Airtac SAI200 Standard Cylinder SAI200AX450 the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when application thrust requirements exceed the 10053 N push force of the 160 mm bore variant but do not mandate the absolute maximum 1.0 MPa output. Operating speed for this large-bore model is rated at 30-500 mm/s. Because the 450 mm stroke creates a long unsupported rod extension, external guide rails or a guided cylinder carriage should be used to prevent rod-bearing bending and premature seal failure under side loads.
As a standard double-acting actuator, this model relies on continuous air pressure to hold its position; if air is exhausted or a valve is centered, the piston will drift. For applications requiring static load holding without live pressure, specify the SAIL pneumatic lock or BSAI clamp-lock variant. To ensure seamless ISO 15552 interchangeability, verify the 450 mm stroke, G3/4 port size, and compatible mounting accessories like the TC trunnion or FA flange.
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 SAI200AX450 FAQ
At a standard operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
Yes, the SAI200X450 is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing setups utilizing matching mounting accessories, provided the G3/4 port and 450 mm stroke align with your current fixture.
