About the Airtac SAI200 Standard Cylinder SAI200AX300
The AirTAC SAI200X300 is a robust double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Operating at 0.5 MPa, it generates a substantial 15708 N of push force, making it well-suited for demanding pressing and lifting operations over its 300 mm stroke.
Built to precise dimensional standards, this extruded aluminum barrel unit features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to manage kinetic energy, operating efficiently within a 30-500 mm/s speed range.

Where the Airtac SAI200 Standard Cylinder SAI200AX300 Is Used
Heavy-Duty Stamping
Provides the immense force required for forming and stamping thick metal components in automotive production lines.
Massive Load Elevation
Ideal for lifting heavy machinery or palletized goods where a 15708 N push force at 0.5 MPa is necessary.
Industrial Clamp Jigs
Secures large fabricated weldments or cast parts firmly in place during heavy machining operations.
Is the Airtac SAI200 Standard Cylinder SAI200AX300 the Right Cylinder?
Selecting this 200 mm bore unit is appropriate when the 160 mm bore (delivering 10053 N at 0.5 MPa) cannot meet your load requirements. For a 300 mm stroke, the extended rod is highly susceptible to bending under side loads; utilizing an external guide rail or a dedicated guided cylinder is strongly recommended to prevent premature wear on the rod bearing.
As a true ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 cylinders. If the application requires the load to be held securely in place without continuous air pressure, this standard SAI model will vent and drift; you must specify the SAIL (pneumatic lock) or BSAI (clamp-lock) variant instead.
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 SAI200AX300 FAQ
At 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N.
No, the standard SAI200X300 is double-acting and will drift if air pressure is removed. For secure load holding, you should use the SAIL (air-released lock) or BSAI (clamp-lock) variant.
