The AirTAC AirTAC SAI200X165-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust push force of 15708 N at 0.5 MPa, this 200mm bore unit is built to move substantial loads. The 165mm stroke provides the precise extension needed for large clamping, pressing, or lifting operations.
This variant features a standard carbon steel piston rod and includes a magnetic piston for position detection. The -S designation ensures seamless compatibility with CMSE and DMSE reed switches, which mount directly into the dual sensor grooves machined into the extruded aluminum barrel. Fluid handling is rated for filtered air at 40 um, operating reliably between -20 and +70 C.

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 required to form, stamp, and crimp thick metal components in automotive and structural fabrication lines.
Actuates heavy molding platens and securely holds large tooling, utilizing the 165mm stroke to clear deep mold cavities during part ejection.
Generates consistent, high-tonnage linear pressure for bending thick plate steel, taking advantage of the stable 200mm profile barrel.
Selecting this 200mm bore cylinder is appropriate when applications require exceptionally high thrust that smaller bores cannot provide, such as replacing a 160mm bore unit that only offers 10053 N push force at 0.5 MPa. Because the SAI200X165-S is a true ISO 15552 profile cylinder, it offers a dimensionally interchangeable mounting interface, allowing a straightforward drop-in replacement for other ISO 15552 cylinders without altering the machine footprint.
Ensure your setup accounts for the PT tapered port threads and the G3/4 air supply connection. If the machinery must hold a load in place during a complete loss of air pressure or when the valve is centered, this standard cylinder will drift and drop the load. For those critical safety requirements, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of relying on the adjustable air cushions, which only decelerate the piston near the stroke ends.
Quick checklist
At an operating pressure of 0.5 MPa, this 200mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
Yes, the SAI200X165-S is a genuine ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders. You can drop it into existing foot (LB) or flange (FA/FB) mounts seamlessly.
