About the Airtac SAI200 Standard Cylinder SAI200AX145S
The AirTAC SAI200X145-S is a double-acting ISO 15552 profile pneumatic cylinder built for heavy-duty tasks. It generates 15708 N of push force at 0.5 MPa, making it suitable for high-load automation. The 145 mm stroke handles substantial linear movements. Equipped with a -S magnet, it integrates seamlessly with CMSE and DMSE reed switches.
This model features an SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance. It uses PT tapered port threads and includes adjustable air cushions at both ends. As a genuine AirTAC component, it ensures reliable performance in demanding industrial environments.

Where the Airtac SAI200 Standard Cylinder SAI200AX145S Is Used
Heavy Metal Forming
Ideal for driving large presses or stamping equipment where 15708 N of force is required to shape thick metal components.
Automotive Assembly
Provides the robust linear motion needed for lifting and positioning heavy chassis frames or engine blocks on the production line.
Pallet Handling
Suitable for pushing or lifting fully loaded heavy pallets, utilizing the 145 mm stroke to index materials efficiently.
Is the Airtac SAI200 Standard Cylinder SAI200AX145S the Right Cylinder?
Select this 200 mm bore when 160 mm falls short, as the 160 bore provides 10053 N at 0.5 MPa compared to this model's 15708 N. The 145 mm stroke avoids the extreme side-load risks of longer strokes, but always ensure the load is guided to prevent rod bearing wear. For applications requiring position holding without air pressure, consider the SAIL or BSAI variants. This cylinder is dimensionally interchangeable with other ISO 15552 profile cylinders, matching the 200 mm bore, 145 mm stroke, PT port, and standard mounting accessories.

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.
