About the Airtac SAI200 Standard Cylinder SAI200AX280S
The AirTAC SAI200X280-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 280 mm stroke is well within the 1500 mm standard limit, making it ideal for moving large masses in demanding industrial environments.
Built with a SUS420J2 stainless steel rod (material code A), this model offers superior corrosion resistance compared to standard carbon steel. The integrated magnet (-S) enables precise position detection using CMSE or DMSE switches housed in the dual-side sensor grooves of the extruded aluminum barrel. Fluid connections use PT tapered threads to ensure robust, leak-free pneumatic sealing under high dynamic loads.

Where the Airtac SAI200 Standard Cylinder SAI200AX280S Is Used
Heavy Stamping
Provides the high 15708 N push force required to actuate large metal stamping presses and forming dies.
Automotive Assembly
Lifts and positions heavy chassis components or powertrain modules along vehicle production lines.
Bulk Material Handling
Drives large diverter gates and heavy-duty sorting mechanisms in high-throughput logistics centers.
Is the Airtac SAI200 Standard Cylinder SAI200AX280S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when forces exceed the 10053 N push capacity of the 160 mm bore at 0.5 MPa. Because the 280 mm stroke is substantial, external guides or a fully guided cylinder are strongly recommended to prevent rod-bearing bending under any side load. For applications requiring the load to be held mechanically without continuous air pressure, this standard SAI will drift; instead, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders, matching the 200 mm bore, 280 mm stroke, G3/4 port, and standard mounting accessories exactly.
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 SAI200AX280S FAQ
At 0.5 MPa, it provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder does not hold position without live pressure and will drift. For secure load holding, use the SAIL (air-released lock) or BSAI (clamp-lock) variants.
