The AirTAC AirTAC SAI200X80-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 80mm 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 SAI200X80-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N push force at 0.5 MPa and a maximum theoretical capacity of 3204 kgf at 1.0 MPa. Its 80 mm stroke suits short, high-power positioning tasks. This configuration features a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet for seamless CMSE or DMSE sensor integration.
Unlike traditional tie-rod designs, this extruded aluminum profile barrel provides a rigid, standardized mounting interface per ISO 15552. It includes adjustable air cushions at both ends to manage heavy impact loads, and utilizes PT tapered port threads for a secure, leak-free pneumatic connection in demanding industrial environments.

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 immense 15708 N push force at 0.5 MPa required to form and stamp thick metal sheets in automated fabrication lines.
Secures oversized injection molds or heavy industrial tooling with a short 80 mm stroke and high rigidity during high-pressure cycles.
Generates reliable, high-tonnage linear force for bending and forming structural steel components in heavy machinery manufacturing.
Selecting this 200 mm bore cylinder is appropriate when applications require extreme push and pull forces that exceed the 10053 N at 0.5 MPa offered by the smaller 160 mm bore variant. If the 80 mm stroke is insufficient for your cycle, the 200 mm bore platform supports standard strokes up to 1500 mm. For heavy payloads requiring precise lateral stability, pair this cylinder with an external guide rail to prevent rod-bearing bending.
This model uses a G3/4 port and is dimensionally interchangeable with other ISO 15552 profile cylinders. Note that the standard double-acting design relies on continuous air pressure to hold position; if your application requires mechanical load holding upon air loss or exhaust, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of relying on the cushions, which only decelerate the piston near stroke end.
Quick checklist
The SAI200X80-S generates 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, with a theoretical maximum of 3204 kgf at 1.0 MPa.
No, the standard SAI cylinder does not hold its position when air pressure is lost or exhausted, as the adjustable cushions only decelerate the piston near the end of the stroke. For fail-safe load holding, use the SAIL or BSAI locking variants.
