About the Airtac SAI200 Standard Cylinder SAI200AX120S
The AirTAC SAI200X120-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200mm bore unit is built to move massive loads reliably. The 120mm stroke provides the precise short-travel movement often required for high-tonnage pressing or heavy clamping operations.
This configuration includes a magnet for direct mounting of CMSE or DMSE sensor switches along the extruded aluminum barrel grooves. To withstand harsh environments, the piston rod is constructed from SUS420J2 stainless steel, and the pneumatic ports feature a PT tapered thread design. Adjustable air cushions at both ends absorb kinetic energy to protect machinery from end-of-stroke impact.

Where the Airtac SAI200 Standard Cylinder SAI200AX120S Is Used
Heavy-Duty Stamping
Provides the robust 15708 N push force required to form thick metal components in automated stamping presses.
Injection Molding Extraction
Utilizes the integrated magnet and SUS420J2 stainless steel rod to reliably extract heavy molded parts from high-temperature environments.
Industrial Clamping
Secures large fabricated steel structures during welding or machining operations using its massive 120mm stroke and high-tonnage clamping force.
Is the Airtac SAI200 Standard Cylinder SAI200AX120S the Right Cylinder?
Selecting this 200mm bore cylinder is appropriate when application forces exceed the 10053 N push capacity of the 160mm variant at 0.5 MPa. If the 15708 N output is excessive, stepping down to the 160mm bore optimizes air consumption while maintaining sufficient thrust. The 120mm stroke is well below the 1500mm maximum standard, keeping the rod assembly compact and highly resistant to side-load bending.
Because the SAI is a double-acting pneumatic actuator, it cannot hold a load in place if air pressure drops or the valve is centered. For vertical loads or applications requiring fail-safe position holding, pair this cylinder with an external pilot-operated check valve or specify the BSAI bidirectional clamp-lock variant. As a true ISO 15552 profile cylinder, it provides a drop-in dimensional replacement for other ISO 15552 cylinders, utilizing a G3/4 port and compatible with TC trunnion or FA flange 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.
