The AirTAC AirTAC SAI200X55 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 55mm 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 SAI200X55 is a formidable double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N of push force at just 0.5 MPa, this 200 mm bore actuator is built to move massive loads. The 55 mm stroke provides rapid, high-impact linear motion within a compact footprint. As a genuine AirTAC component, it ensures reliable operation in demanding pneumatic systems.
This specific configuration incorporates a SUS420J2 stainless steel piston rod (material code A), offering superior corrosion resistance and mechanical strength compared to standard carbon steel. The barrel features integrated sensor grooves on both sides for direct CMSE or DMSE switch mounting, though this unit is specified without a magnet. It utilizes PT tapered port threads and includes adjustable air cushions at both ends to decelerate the heavy 200 mm piston smoothly, minimizing end-of-stroke impact.

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 force required to drive heavy metal stamping and forming presses, utilizing the short 55 mm stroke for rapid, high-impact cycling.
Ideal for compacting and pressing dense materials or bearings into housings, where immense thrust must be delivered in a tightly constrained vertical space.
Actuates large-scale process valves or heavy gate mechanisms, relying on the SUS420J2 stainless steel rod for durability against environmental moisture.
Selecting the SAI200X55 is appropriate when your application requires extremely high thrust within a short extension distance. If 15708 N at 0.5 MPa is excessive, stepping down to a 160 mm bore yields 10053 N, which may offer better energy efficiency. Because this is a short 55 mm stroke, side-load bending is minimal, but the sheer mass of the 200 mm piston still requires robust external guiding to prevent rod bearing wear. The adjustable cushions are tuned to absorb kinetic energy, but they do not lock the load; if the air supply is exhausted, the rod will drift. For position holding without live pressure, integrate an external pilot-operated check valve or specify a BSAI clamp-lock variant. This model is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders, matching the 200 mm bore, 55 mm stroke, PT G3/4 ports, and standard mounting accessories.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X55 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.
No, the standard SAI200X55 is a double-acting cylinder and cannot hold a load without live pressure. The adjustable air cushions only decelerate the piston at stroke end; they do not function as a brake. For failsafe load holding, use an external rod lock or the AirTAC BSAI bidirectional clamp-lock variant.
