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 built for heavy-duty automation. It delivers a robust 15708 N push force at 0.5 MPa and 21991 N at 0.7 MPa, making it suitable for high-tonnage pressing and heavy load manipulation. The 650 mm stroke provides extensive travel for large-scale machinery.
This model is configured with SUS420J2 stainless steel for the piston rod (material code A), offering superior corrosion resistance compared to standard carbon steel. It utilizes PT tapered port threads for a secure, leak-free pneumatic connection. The extruded aluminum barrel features dual sensor grooves, allowing direct mounting of CMSE or DMSE switches if a magnet is added later.

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.
Generates up to 21991 N of thrust at 0.7 MPa, ideal for driving large metal stamping presses and forming heavy-gauge materials.
The 650 mm stroke accommodates the long-travel requirements of automotive and heavy equipment assembly lines, ensuring components are seated properly.
Provides the high force necessary to actuate massive bulkhead doors, heavy lifting platforms, and large-scale robotic gripper assemblies.
With a 200 mm bore, this cylinder sits at the top of the standard SAI range, offering maximum thrust. If 15708 N at 0.5 MPa is excessive for your cycle and you want to reduce air consumption, stepping down to the 160 mm bore yields 10053 N. Because this unit features a 650 mm stroke, the unsupported rod length is substantial; lateral side loads will cause rod-bearing bending and premature seal wear. Always pair this cylinder with an external guide mechanism or a dedicated guided cylinder to absorb lateral forces.
As a genuine ISO 15552 profile cylinder, it provides drop-in dimensional interchangeability with other ISO 15552 standard cylinders. To match this configuration, specify a 200 mm bore, 650 mm stroke, PT port threads, SUS420J2 rod material, and your required mounting accessories (such as a TC trunnion or CA clevis). Note that standard SAI cylinders do not hold position when air pressure is removed; for fail-safe load holding, consider the BSAI clamp-lock variant.
Quick checklist
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X650 is a true ISO 15552 profile cylinder, meaning its mounting dimensions are standardized for direct drop-in replacement of other ISO 15552 cylinders with a 200 mm bore and 650 mm stroke.
