The AirTAC AirTAC SAI200X50 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 50mm 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 SAI200X50 is a formidable double-acting ISO 15552 profile cylinder engineered for extreme force generation. Delivering a substantial 15708 N of push force at just 0.5 MPa, this 200mm bore unit is tailored for heavy-duty pressing and lifting tasks. The 50mm stroke provides rapid, high-impact linear motion within a compact footprint.
Unlike traditional tie-rod actuators, this model utilizes an extruded aluminum barrel equipped with dual sensor grooves, allowing for direct mounting of CMSE or DMSE switches when a magnet is specified. The standard configuration features a robust carbon steel piston rod and PT tapered port threads, ensuring reliable, high-flow pneumatic connectivity for massive air volumes.

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 intense 15708 N push force required for stamping, bending, and forming thick metal sheets in primary fabrication lines.
Delivers rapid, high-power ejection of large forged or cast parts from heavy molds, utilizing its short 50mm stroke for quick cycling.
Ideal for pressing bearings, bushings, or heavy assemblies into housings, where absolute maximum thrust is necessary within a short travel distance.
Selecting the SAI200X50 is appropriate when applications demand maximum thrust, such as replacing lower force units like the 160mm bore (which yields 10053 N at 0.5 MPa) for heavier workpieces. Because the 50mm stroke is relatively short, side-load stress on the rod bearing is minimal compared to longer extensions. However, for multi-axis stability, external guide rails are still recommended.
As a true ISO 15552 standard cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 profile actuators, matching mounting interfaces exactly. Note that this standard cylinder cannot hold a load if air pressure is lost; for fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants.
Quick checklist
At 0.5 MPa, this 200mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 1.0 MPa, it can reach a theoretical maximum of 3204 kgf.
No, the standard SAI200X50 cannot hold a load without live air pressure. The adjustable air cushions only decelerate the piston at stroke ends. For secure load holding, use the SAIL (lock) or BSAI (clamp-lock) variants.
