The AirTAC AirTAC SAI200X135 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 135mm stroke, G3/4 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.
The AirTAC SAI200X135 is a double-acting ISO 15552 profile cylinder engineered for massive thrust, delivering 15708 N push force at 0.5 MPa. Its extruded aluminum barrel omits tie rods while providing a standardized mounting interface. This 135 mm stroke is a made-to-order dimension tailored for specific large-scale machinery.
Featuring a robust carbon steel piston rod and PT tapered port threads, this unit ensures secure high-pressure pneumatic connections. The barrel includes dual sensor grooves for CMSE or DMSE switches, though this specific configuration omits the internal magnet, meaning electronic position sensing is not supported without modification.

Related SAI-family variants: SAID (double rod), SAIJ (adjustable stroke), SAIL (with lock), SAIF (with valve), BSAI (enclasp / clamp-lock), and SAI-S with built-in magnet. Rod material: carbon steel (blank) / SUS420J2 (A) / SUS304 (B); seals: TPU (blank) / Viton H / NBR N.
Provides the 15708 N push force at 0.5 MPa required to drive heavy-duty stamping presses and form thick gauge metal components.
Clamps large injection molds securely with up to 3204 kgf theoretical force, ensuring zero parting line flash during high-pressure injection.
Drives massive structural bearings and pins into heavy machinery housings, utilizing the 135 mm stroke for deep insertion tasks.
Selecting this 200 mm bore over the 160 mm variant upgrades your 0.5 MPa output from 10053 N to 15708 N, providing the extra push needed for heavy industrial forming or clamping. For applications requiring position holding without live air pressure, a standard SAI will drift; specify the SAIL locking variant or an external BSAI clamp-lock cylinder instead.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 200 mm bore interface. Ensure your setup matches the G3/4 port and utilizes appropriate FA or FB flange accessories to handle the substantial weight and reaction forces.
Quick checklist
At 0.5 MPa, it provides 15708 N of push force and 15080 N of pull force. At 1.0 MPa, the theoretical maximum force is 3204 kgf.
Yes, the SAI200X135 is dimensionally interchangeable per ISO 15552 standards, allowing it to serve as a drop-in replacement for other profile cylinders with matching 200 mm bores and G3/4 ports.
