About the Airtac SAI200 Standard Cylinder SAI200AX40S
The AirTAC SAI200X40-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N push force at 0.5 MPa. This 200 mm bore actuator uses a short 40 mm stroke, making it ideal for high-force pressing and clamping operations where full extension length is restricted. The extruded aluminum barrel design omits tie rods for a clean exterior.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The -S suffix indicates a built-in magnet, allowing seamless integration with CMSE or DMSE reed switches via the dual sensor grooves machined into both sides of the barrel.

Where the Airtac SAI200 Standard Cylinder SAI200AX40S Is Used
Heavy-Duty Stamping
Provides 15708 N of push force at 0.5 MPa for short-stroke metal forming and stamping tasks in fabrication plants.
Industrial Clamping
Secures large molds or heavy workpieces during machining, utilizing the 200 mm bore capacity and 40 mm travel.
Press Fit Assembly
Drives large bearings or bushings into heavy housings, benefiting from the SUS420J2 rod and precise 30-500 mm/s speed range.
Is the Airtac SAI200 Standard Cylinder SAI200AX40S the Right Cylinder?
Selecting this 200 mm bore over the neighbouring 160 mm bore increases your 0.5 MPa push thrust from 10053 N to 15708 N, providing the extra force needed for heavy stamping tasks. Because the 40 mm stroke is very short, side-load stress on the rod bearing is minimal, meaning no external guide rail is strictly necessary for basic vertical pressing.
Note that the standard SAI200X40-S relies on live air pressure to maintain its position; if pneumatic supply is lost, the piston will drift. For applications that must hold a load safely without constant air pressure, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. This model uses PT tapered port threads (G3/4) and is dimensionally interchangeable per ISO 15552, so it serves as a drop-in replacement for other ISO 15552 profile cylinders when paired with appropriate CA clevis or LB foot mounts.

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.
