The AirTAC AirTAC SAI200X450-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 450mm 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 SAI200X450-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It generates a substantial 15708 N of push force at 0.5 MPa, making it well-suited for moving massive loads over its 450 mm stroke. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that drops directly into standardized ISO 15552 mounting footprints.
Equipped with a magnetic piston (-S), this unit supports position sensing via CMSE or DMSE switches fitted into the dual sensor grooves. The standard carbon steel piston rod handles rugged industrial environments, while adjustable air cushions at both ends absorb kinetic energy to protect end-of-stroke components.

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 high thrust necessary for pressing, stamping, and forming thick metal components in automotive and structural fabrication.
Actuates massive platens to seat bearings, bushings, or heavy machinery sub-assemblies that require consistent 15000+ Newton force.
Drives heavy-duty diverter arms and gates on mining or aggregate conveyors to route dense, high-volume product flows.
Selecting this 200 mm bore cylinder is appropriate when application thrust requirements exceed the 10053 N generated by the smaller 160 mm bore at 0.5 MPa. If the 15708 N output at 0.5 MPa is excessive, stepping down to the 160 mm variant offers a more compact footprint and lower air consumption. The PT tapered port threads ensure a robust, leak-free pneumatic connection.
Because this model features a 450 mm stroke, the extended rod is susceptible to bending under lateral loads. Implement an external guide rail or utilize a guided cylinder variant to prevent rod-bearing damage. Note that standard double-acting cylinders drift when air pressure is removed; if the machinery requires true load holding during exhaust or valve centering, specify an external pilot check valve or select the BSAI clamp-lock series.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. The theoretical maximum force at 1.0 MPa is 3204 kgf.
Yes. The SAI200X450-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts matching the standard, utilizing the G3/4 port and standard trunnion or flange accessories.
