The AirTAC AirTAC SAI200X85 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 85mm 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 SAI200X85 is a robust double-acting ISO 15552 profile cylinder engineered for immense pushing power, delivering 15708 N of thrust at just 0.5 MPa. Featuring a 200 mm bore and an 85 mm non-standard made-to-order stroke, this extruded aluminum barrel unit is built for heavy-duty industrial tasks.
Unlike basic pneumatic actuators, this model incorporates a standard carbon steel piston rod for high tensile strength under heavy loads. It utilizes PT tapered port threads (G3/4) for secure, leak-free pneumatic connections and includes adjustable air cushions at both ends to decelerate the massive 200 mm piston smoothly.

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 actuate heavy stamping dies and form thick sheet metal blanks.
Generates reliable holding pressure for large industrial molds, utilizing its 200 mm bore and adjustable end cushions to handle sudden impact loads.
Powers heavy-duty diverter arms on mining or aggregate conveyors, moving substantial bulk material loads with precise 85 mm stroke movements.
Selecting this 200 mm bore actuator is appropriate when application forces exceed the 10053 N push force of the 160 mm bore variant at 0.5 MPa. Because the 85 mm stroke is a non-standard length, expect a made-to-order lead time. For any stroke under 300 mm, side-load stress on the rod bearing is minimal, but always ensure the load is rigidly guided to prevent piston binding.
This actuator relies on live air pressure to move; it will drift if system pressure drops or the directional valve is centered. If your machinery requires fail-safe load holding, integrate an external pilot-operated check valve or transition to the AirTac SAIL or BSAI locking cylinder variants. This model is dimensionally interchangeable per ISO 15552, serving as a direct drop-in replacement for other ISO 15552 profile cylinders.
Quick checklist
The SAI200X85 delivers a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X85 is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other ISO 15552 standard cylinders. It uses a G3/4 port and standard carbon steel rod.
