The AirTAC AirTAC SAI200X70 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 70mm 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 SAI200X70 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty pneumatic applications. It features a 200mm bore and a 70mm stroke, delivering a substantial push force of 15708 N at 0.5 MPa. The extruded aluminum barrel design eliminates tie rods while maintaining strict dimensional interchangeability with standard ISO 15552 mounting interfaces.
This specific model is equipped with a standard carbon steel piston rod and PT tapered port threads. For environments requiring higher heat resistance, the cylinder can be configured with Viton (H) seals, and if position sensing is needed, the barrel includes dual-sided sensor grooves compatible with CMSE or DMSE switches 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 push force at 0.5 MPa required for pressing, forming, and stamping thick metal components in automotive assembly lines.
Secures heavy industrial molds and dies in injection molding or casting setups where a short 70mm clamping stroke is sufficient.
Handles high-tonnage actuation tasks in extrusion processes, utilizing its 200mm bore and robust carbon steel rod for reliable cyclic operation.
Selecting this 200mm bore cylinder is ideal when your application demands extreme force, as stepping down to a 160mm bore reduces the 0.5 MPa push force to 10053 N. The 70mm stroke provides quick, short linear movement within a compact footprint. Because the stroke is under 300mm, rod bearing bending from side loads is less severe than in longer strokes, but external guidance is still recommended for heavy lateral loads.
This SAI variant uses PT tapered ports and a standard carbon steel rod. If the machinery loses air pressure or the valve centers, the piston will drift and cannot hold a load; for fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of relying on the standard adjustable air cushions.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X70 delivers 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, the SAI200X70 is dimensionally interchangeable per ISO 15552. Its profile barrel design and standard mounting dimensions allow it to replace other ISO 15552 profile cylinders seamlessly without modifying the existing machine footprint.
