The AirTAC AirTAC SAI200X85-S 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-S is a robust double-acting ISO 15552 profile cylinder engineered for immense pushing power, generating 15708 N of thrust at just 0.5 MPa. Its extruded aluminum barrel design omits tie rods for a sleeker profile while maintaining strict dimensional interchangeability with standard ISO 15552 mounting interfaces. The 85 mm stroke is a custom non-standard length, made-to-order for specific short-travel heavy-duty tasks.
This configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for seamless position sensing. You can mount CMSE or DMSE series switches directly into the sensor grooves machined on both sides of the barrel. Fluid ports feature a PT tapered thread type, ensuring tight, high-pressure pneumatic connections for this high-flow actuator.

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 pressing force required for short-stroke forming, bending, and stamping thick metal sheets in automotive fabrication.
Acts as a heavy-duty actuator in large press lines, delivering consistent 21991 N force at 0.7 MPa to securely clamp and form heavy plate steel.
Generates sudden, high-impact push force to eject dense molded parts or heavy machined components from stationary jigs.
Selecting this 200 mm bore size is appropriate when applications require maximum thrust—up to 15708 N at 0.5 MPa or 21991 N at 0.7 MPa. If your load demands are lower, stepping down to a 160 mm bore provides 10053 N at 0.5 MPa, which may offer a more compact and economical footprint. Because this is a custom 85 mm stroke, verify your machine envelope allows for the extended rod length and mounting accessories like FA or FB flanges.
Remember that a standard SAI cylinder relies on live air pressure to hold its position; it will drift if pressure is lost. For critical loads requiring fail-safe holding, integrate an external rod lock or specify the SAIL or BSAI clamp-lock variant. Furthermore, operating speed for this 200 mm bore is rated at 30-500 mm/s; ensure your flow controls are appropriately sized to prevent shock at these massive force levels.
Quick checklist
This 200 mm bore cylinder generates a theoretical push force of 15708 N at 0.5 MPa, 21991 N at 0.7 MPa, and 28274 N at 0.9 MPa. The pull force at 0.5 MPa is 15080 N.
Yes, the SAI200X85-S is a genuine AirTAC profile cylinder built to strict ISO 15552 mounting dimensions. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided your fluid porting matches the G3/4 PT threaded ports.
