The AirTAC AirTAC SAI200X80 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 is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N of push force at just 0.5 MPa. With an 80 mm stroke, this extruded aluminum barrel unit is built to move heavy masses in confined axial spaces. It features a robust 40 mm piston rod constructed from SUS420J2 stainless steel, providing excellent resistance to corrosion and mechanical wear in demanding industrial environments.
Because it adheres strictly to ISO 15552 mounting dimensions, this cylinder serves as a direct drop-in replacement for other profile cylinders in the same standard. It uses PT tapered port threads and lacks a standard piston magnet, meaning position sensing requires external proximity switches rather than embedded groove sensors.

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 thick gauge sheet metal and operate heavy-duty stamping dies.
Secures oversized injection molds or heavy industrial castings during secondary machining and finishing processes.
Compresses large volumes of scrap material or bulk powders into dense blocks for efficient logistics and waste handling.
Selecting this 200 mm bore over the neighboring 160 mm bore increases your 0.5 MPa push thrust from 10053 N to 15708 N, a critical step up for high-tonnage pressing or lifting. The 80 mm stroke minimizes rod overhang, inherently reducing side-load stress on the rod bearing compared to longer travel variants.
For applications requiring fail-safe load holding upon air loss, note that the standard adjustable air cushions only decelerate the piston at stroke end and do not lock the rod. You must integrate an external pilot-operated check valve or specify a BSAI clamp-lock variant to prevent drifting under load. Replacement matching is straightforward: 200 mm bore, 80 mm stroke, PT G3/4 ports, standard mounting accessories (FA/FB flange or TC trunnion), and no -S magnet.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, as a genuine ISO 15552 profile cylinder, its center-to-center mounting distances and port sizes are dimensionally interchangeable with other ISO 15552 cylinders, allowing direct replacement without frame modifications.
