About the Airtac SAI200 Standard Cylinder SAI200AX25S
The AirTAC SAI200X25-S is a double-acting ISO 15552 profile cylinder engineered for extreme force tasks, delivering a robust 15708 N of push force at just 0.5 MPa. Its 25 mm stroke is tailored for high-impact pressing, clamping, and short-travel heavy-duty automation. As a genuine AirTAC component, it ensures reliable performance in the most demanding industrial environments.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance and reduced wear in harsh settings. It includes a built-in magnet (-S) for direct compatibility with CMSE and DMSE series reed switches, which mount seamlessly into the dual-sided sensor grooves on the extruded aluminum barrel. The cylinder utilizes PT tapered port threads and supports adjustable air cushions at both ends to decelerate the massive 200 mm piston smoothly.

Where the Airtac SAI200 Standard Cylinder SAI200AX25S Is Used
Heavy-Duty Stamping
Provides the immense 15708 N push force at 0.5 MPa required for short-stroke metal forming, stamping, and riveting operations.
Industrial Clamping
Ideal for securing heavy structural components or large molds during machining and welding processes, utilizing its 200 mm bore power.
High-Force Pressing
Excels in short-travel pressing and assembly tasks where massive, controlled force is needed over a compact 25 mm stroke.
Is the Airtac SAI200 Standard Cylinder SAI200AX25S the Right Cylinder?
Selecting this 200 mm bore cylinder is appropriate when application forces exceed the 10053 N (at 0.5 MPa) capacity of the 160 mm bore size, requiring the maximum standard force class available in the SAI range. The very short 25 mm stroke minimizes rod-bearing bending moments, making it highly rigid and ideal for concentrated pressing operations without the side-load risks inherent to longer strokes.
Because it is a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders of the same bore, simplifying retrofits and machine upgrades. Always specify the 200 mm bore, 25 mm stroke, PT port thread, and the -S magnet requirement when requesting a quote. Note that the standard adjustable cushions only decelerate the piston near the stroke end; they do not hold a load. If your application requires position holding without live air pressure, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants 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.
