The AirTAC AirTAC SAI200X290-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 290mm 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 SAI200X290-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Delivering a substantial 15708 N of push force at 0.5 MPa, this 200mm bore unit is built to move massive loads reliably. The 290mm stroke provides the extended travel needed for large presses and heavy material handling.
Equipped from the factory with a magnet for position sensing, this model integrates seamlessly with CMSE and DMSE reed switches fitted into the dual sensor grooves along the extruded aluminum barrel. The piston rod utilizes a robust carbon steel construction for high tensile strength under extreme axial loads, while the tapered PT port thread ensures a secure, leak-free pneumatic connection.

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 robust 15708 N push force required to actuate large mechanical presses and form thick steel components securely.
Shifts heavy injection molds or die sets into and out of machinery, utilizing the 290mm stroke to fully clear the work envelope safely.
Drives heavy-duty diverter arms on high-capacity aggregate or bulk material conveyors where lower bore cylinders would stall under the weight.
Selecting this 200mm bore cylinder is appropriate when applications require extremely high thrust that smaller bores cannot provide, such as replacing multiple smaller actuators with a single centralized motion source. If the full 15708 N push force at 0.5 MPa is unnecessary, stepping down to a 160mm bore yields 10053 N, which may save space and air consumption.
Because the 290mm stroke exceeds the 300mm threshold where side-load risks become prominent, careful mounting is essential to prevent rod-bearing bending. Utilize external guide rails or a guided cylinder carriage to support the load, as the standard carbon steel rod is designed for axial compression rather than lateral deflection. Furthermore, if the machinery requires the load to be held statically during a complete loss of air pressure, the standard SAI will drift; utilize the BSAI clamp-lock variant or an external pilot-operated check valve for secure positioning. For direct mounting interchangeability with competing actuators, match the 200mm bore, 290mm stroke, G3/4 port, and appropriate TC trunnion or FA flange accessories, ensuring a magnet (-S) is specified if switch tracking is needed.
Quick checklist
At a standard operating pressure of 0.5 MPa, this 200mm bore cylinder generates 15708 N of push force and 15080 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
No, the standard SAI cylinder relies on air pressure and will drift or drop if pressure is lost. The adjustable air cushion only decelerates the piston at stroke end and does not function as a brake. For static load holding, use the BSAI clamp-lock variant or an external rod lock.
