The AirTAC AirTAC SAI200X165 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 165mm 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 SAI200X165 is a double-acting ISO 15552 profile cylinder engineered for immense pushing power, yielding 15708 N of thrust at just 0.5 MPa. This specific configuration ships with a 165 mm stroke and a robust SUS304 stainless steel rod (material code B) to maximize corrosion resistance in hostile washdown environments. Because 165 mm is not a standard catalog increment, it is produced as a made-to-order stroke.
This variant utilizes a PT tapered port thread and lacks an internal magnet, meaning it is optimized purely for mechanical actuation rather than electronic position sensing. For operations requiring extreme heat resilience up to +70 C, the standard TPU seals can be swapped for Viton (code H). If your machinery demands bidirectional clamping under zero air pressure, consider integrating the related BSAI 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 at 0.5 MPa required to seat large stamping dies and form thick gauge metals.
Actuates heavy core pulls and clamping mechanisms on large-tonnage injection molding machinery using its SUS304 rod.
Transfers heavy structural beams or plates into hydraulic presses where corrosion resistance and raw power are mandatory.
Selecting this 200 mm bore is appropriate when 160 mm (10053 N at 0.5 MPa) cannot generate enough force to move the load, but you want to avoid jumping to larger custom actuators. Operating speed for this bore is capped at 30-500 mm/s to maintain structural integrity during transit.
Because this is a non-standard 165 mm stroke, you must verify your mounting interface. It provides true ISO 15552 dimensional interchangeability, allowing a drop-in replacement for other profile cylinders. Note that a plain SAI does not hold its position if air pressure drops; the adjustable air cushions only decelerate the piston near the stroke ends. For positive holding under lost pressure, specify an external rod lock.
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 SAI200X165 is a profile cylinder with a standardized ISO 15552 mounting interface, making it dimensionally interchangeable with other ISO 15552 cylinders. It uses a G3/4 port.
