The AirTAC AirTAC SAI200X55-S 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-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust requirements, delivering 15708 N of push force at just 0.5 MPa. Its 55 mm stroke provides compact motion for heavy-duty pressing or holding tasks. Built with an extruded aluminum barrel, it omits traditional tie-rods for a cleaner profile while maintaining strict standardized mounting dimensions.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. The integrated -S magnet enables direct mounting of CMSE and DMSE series sensor switches along the dual grooves on the barrel. For applications needing position holding without continuous air pressure, consider the BSAI bidirectional clamp-lock variant.

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 massive 15708 N push force required to form, pierce, or stamp thick metal plates in automated fabrication lines.
Ideal for heavy-duty industrial presses that require short, powerful strokes to assemble bearings or compress dense materials.
Holds large structural components securely in place during welding or machining, utilizing the SUS304 rod for rugged reliability.
Selecting this 200 mm bore cylinder is ideal when the 160 mm bore (providing 10053 N at 0.5 MPa) cannot generate sufficient force for your heaviest loads. Because the 55 mm stroke is relatively short, side-load risks on the rod bearing are minimal compared to longer strokes. However, if your application involves heavy off-center loads, an external guide is still recommended to prevent premature wear.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard ISO 15552 unit with a 200 mm bore, 55 mm stroke, and G3/4 PT port. Ensure you pair it with appropriate mounting accessories, such as a TC trunnion or CA clevis, and utilize the -S magnet for necessary end-of-stroke feedback. Note that standard pneumatic cushions only decelerate the piston; they do not lock the load when air is exhausted.
Quick checklist
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At the maximum 1.0 MPa, the theoretical push force reaches 3204 kgf.
Yes, the SAI200X55-S is a genuine ISO 15552 profile cylinder. Its standardized mounting interface and G3/4 port make it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke.
