The AirTAC AirTAC SAI200X650 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 650mm 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 SAI200X650 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It delivers a substantial 15708 N push force at 0.5 MPa and a 15080 N pull force, making it well-suited for moving massive loads over its 650 mm stroke. The extruded aluminum barrel design eliminates tie rods while maintaining strict dimensional interchangeability with standard ISO 15552 mounting interfaces.
This specific configuration is built with a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh or washdown environments. It utilizes PT tapered port threads, and because no magnet is specified, it operates without internal sensing magnets. For applications requiring position holding without live air pressure, this base SAI model will drift, so consider the SAIL or BSAI locking variants.

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 at 0.5 MPa required to actuate large metal forming presses and heavy industrial stamping equipment.
Drives large-scale diverter gates and heavy-duty bulk material routing systems in mining or aggregate processing.
Moves substantial chassis components or robotic welding fixtures along the 650 mm stroke with reliable ISO 15552 precision.
Selecting this 200 mm bore cylinder is ideal when 160 mm bore models (providing 10053 N push at 0.5 MPa) lack the necessary thrust for your heaviest machinery. Operating at 30-500 mm/s, it provides smooth motion, but its 650 mm stroke requires careful mounting to prevent rod-bearing bending. Always support long-stroke applications with an external guide or a fully guided cylinder to manage side loads and prevent premature wear.
When ordering a replacement, verify the 200 mm bore, 650 mm stroke, G3/4 PT port thread, and your required mounting accessories like FA flanges or TC trunnions. Because this unit lacks a magnet, you cannot use CMSE or DMSE sensors; if proximity sensing is needed, specify the -S magnet option. Note that the adjustable air cushions at both ends only decelerate the piston and do not hold the load if air pressure is lost.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X650 generates a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, the theoretical push force is 3204 kgf.
Yes, the SAI200X650 is a profile-type cylinder built to ISO 15552 mounting dimensions, making it a drop-in replacement for other ISO 15552 cylinders. Ensure your setup matches the G3/4 PT port and 650 mm stroke.
