The AirTAC AirTAC SAI200X75 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 75mm 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 SAI200X75 is a double-acting ISO 15552 profile cylinder engineered for extreme force generation, delivering a substantial 15708 N of push force at a 0.5 MPa operating pressure. Its 75 mm stroke provides robust linear motion for heavy-duty industrial tasks within a compact footprint.
This model features a corrosion-resistant SUS420J2 stainless steel piston rod, making it suitable for environments where standard carbon steel rods might degrade. The barrel utilizes extruded aluminum with integrated sensor grooves on both sides, and fluid connections use tapered PT threads for secure, leak-free pneumatic hookups.

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 immense 15708 N push force required to actuate large mechanical stamping presses and heavy forming dies at 0.5 MPa.
Utilizes its 75 mm stroke to reliably eject bulky finished plastic or metal components from large injection molding machinery.
Drives oversized industrial process valves and heavy-duty sluice gates where a 200 mm bore is necessary to overcome high flow resistance.
Selecting this 200 mm bore cylinder is appropriate when an application demands up to 15708 N of push force at 0.5 MPa, stepping up significantly from the 160 mm bore class which provides 10053 N. Because the stroke is relatively short at 75 mm, side-load stress on the rod bearing is minimal compared to longer strokes.
As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 standard actuators. Note that this unit lacks a magnet for proximity sensing; adding the -S suffix enables CMSE or DMSE sensor switches. If the machinery requires the load to be physically held in place during a complete loss of air pressure, the standard double-acting SAI will not suffice and an external pilot-operated check valve or the BSAI clamp-lock variant must be specified.
Quick checklist
At 0.5 MPa, the SAI200X75 generates 15708 N of push force and 15080 N of pull force. If operating pressure is increased to 0.7 MPa, the push force reaches 21991 N.
No, the standard double-acting SAI cylinder relies on live air pressure and will drift if pressure is exhausted. To safely hold a suspended load without air, use an external rod lock or select the BSAI bidirectional clamp-lock variant.
