The AirTAC AirTAC SAI200X950 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 950mm 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 SAI200X950 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. It generates a substantial 15708 N of push force at 0.5 MPa, extending across a 950 mm stroke to handle massive loads. This extruded aluminum barrel design omits tie-rods for a clean exterior.
Standard configuration includes a durable carbon steel piston rod and PT tapered port threads. Because this specific stroke exceeds typical catalog offerings, it is produced as a made-to-order unit to ensure strict dimensional compliance. For environments requiring high-temperature resistance, Viton (H) seals can be specified instead of the standard TPU.

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.
Drives large press dies and heavy stamping assemblies where 15708 N of thrust at 0.5 MPa is required to shape thick steel plates.
Actuates multi-ton structural component presses, utilizing the 950 mm stroke to seat heavy machinery housings into exact alignment.
Clamps massive fabricated weldments in automated robotic cells, relying on the robust carbon steel rod for structural rigidity.
Select this 200 mm bore actuator when 160 mm bore units (providing 10053 N at 0.5 MPa) lack the necessary thrust for your heaviest machinery. The 950 mm stroke demands careful mechanical integration. At this length, the unsupported rod is highly susceptible to bending under side loads, so external guide rails or a guided cylinder carriage are mandatory to prevent premature rod-bearing wear.
This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders with identical 200 mm bore, 950 mm stroke, G3/4 ports, and matching mounting accessories like the TC trunnion. Note that a plain SAI cylinder will drift if air pressure is lost; use the BSAI clamp-lock variant if the application requires fail-safe load holding.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides 15708 N of push force and 15080 N of pull force. It achieves a theoretical maximum force of 3204 kgf at 1.0 MPa.
Yes, the SAI200X950 is a true ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 actuators matching the 200 mm bore, 950 mm stroke, and G3/4 port specifications.
