The AirTAC AirTAC SAI200X185 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 185mm 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 SAI200X185 is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N push force at 0.5 MPa. This 200 mm bore and 185 mm stroke configuration is tailored for heavy-duty press operations and massive load manipulation. The extruded aluminum barrel design omits tie rods, providing a clean profile while maintaining structural integrity under high pressure.
To suit demanding environments, this unit features a standard carbon steel piston rod and utilizes tapered PT threads for its G3/4 ports. While the standard seal is TPU, Viton (H) alternatives are available for elevated temperature applications. The barrel also includes integrated sensor grooves on both sides, allowing for direct CMSE or DMSE switch mounting when a magnet is specified.

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 15708 N force at 0.5 MPa necessary to drive large stamping dies and form thick metal plates.
Utilizes the 185 mm stroke to reliably pull heavy molded plastic components from large industrial injection molds.
Delivers consistent high-thrust force for pressing large bearings and heavy mechanical components into industrial housings.
Selecting this 200 bore model is appropriate when forces exceed the 10053 N capability of the 160 mm variant. Operating speed for this large bore is rated at 30-500 mm/s. For this 185 mm stroke, side-load stress on the rod bearing is minimal, but ensuring strict alignment remains critical to prevent premature wear.
Because this is a standard double-acting cylinder, it relies on continuous air pressure to hold a load. If pneumatic pressure drops, the piston will drift. For applications requiring fail-safe position holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. As a true ISO 15552 profile cylinder, it serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 conforming cylinders.
Quick checklist
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, it is a genuine ISO 15552 profile cylinder. Its standardized mounting dimensions make it interchangeable with other ISO 15552 cylinders, though it uses tapered PT port threads.
