About the Airtac SAI200 Standard Cylinder SAI200AX20
The AirTAC SAI200X20 is a double-acting ISO 15552 profile cylinder engineered for immense thrust within a very compact footprint. It generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it suitable for heavy-duty pressing and clamping tasks that require minimal travel.
This configuration features a SUS420J2 stainless steel piston rod for superior corrosion resistance and utilizes PT tapered port threads. While the standard extruded aluminum barrel includes sensor grooves on both sides, this specific unit is supplied without a magnet, so position sensing requires external switches.

Where the Airtac SAI200 Standard Cylinder SAI200AX20 Is Used
Heavy-Duty Stamping
Executes short-traction, high-tonnage stamping and forming operations in metalworking lines.
Industrial Clamping
Secures massive workpieces or molds securely in place during machining and welding processes.
Press Fitment
Drives large bearings or heavy components into housings with precise, short-stroke force.
Is the Airtac SAI200 Standard Cylinder SAI200AX20 the Right Cylinder?
Select this 200mm bore model when 100mm bore cylinders (providing 3927 N at 0.5 MPa) lack the necessary power for high-tonnage operations. The 20mm stroke is optimal for brief, high-force movements. Because the stroke is well under 300mm, rod-bearing bending is not a concern here.
If your application requires the load to remain held when air pressure is removed or exhausted, a standard SAI cylinder will drift. For dead-load holding, integrate an external pilot-operated check valve or specify the BSAI clamp-lock variant.
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 SAI200AX20 FAQ
