The AirTAC AirTAC SAI200X325-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 325mm 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 SAI200X325-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, this 200 mm bore unit effortlessly drives high-mass payloads. The 325 mm stroke provides the extended travel needed for large presses and heavy material handling. As a genuine AirTAC component, it guarantees reliable performance in demanding industrial environments.
This model includes an integrated magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which mount neatly into the dual grooves on the extruded aluminum barrel. It features a robust carbon steel piston rod and PT tapered port threads. For applications requiring extreme heat resistance, the standard TPU seals can be swapped for Viton (H) options to handle higher ambient temperatures.

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 actuate large stamping presses and form heavy-gauge metal components securely.
Utilizes its 325 mm stroke to push and pull substantial injection molds or die sets into and out of machinery safely.
Shifts massive loaded pallets across high-capacity transfer lines, relying on the robust carbon steel rod to absorb impact forces.
Select this 200 mm bore cylinder when your application requires pushing forces beyond the 10053 N provided by the smaller 160 mm bore at 0.5 MPa. If your force requirements are lower, stepping down to the 160 mm bore reduces physical size and air consumption. Because the 325 mm stroke creates a long unsupported rod extension, it is highly susceptible to bending under side loads. Use an external guide rail or a guided cylinder carriage to prevent rod-bearing damage and premature wear.
This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. To match an existing setup, verify the 200 mm bore, 325 mm stroke, G3/4 PT ports, and mounting accessories like the TC trunnion or FA flange. Note that a standard SAI cylinder relies on continuous air pressure to maintain its position; if the air is exhausted, the piston will drift. For dead-load holding without live pressure, specify the SAIL (lock) or BSAI (clamp-lock) variant.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X325-S is a true ISO 15552 profile cylinder, making its mounting dimensions interchangeable with other ISO 15552 compliant cylinders. Ensure your setup matches the G3/4 PT ports and utilizes appropriate mounting accessories like the LB foot or TC trunnion.
