The AirTAC AirTAC SAI200X185-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving massive loads over its 185 mm stroke. As a standardized profile barrel design, it drops directly into existing ISO 15552 mounting interfaces without requiring custom brackets.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and a built-in magnet (-S) that enables seamless integration with CMSE or DMSE sensor switches along the dual grooves on the extruded aluminum barrel. It utilizes PT tapered ports and adjustable air cushions at both ends to manage kinetic energy during operation.

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 robust 15708 N push force required to actuate large stamping presses and heavy-gauge metal forming machinery.
Ideal for extracting heavy molded products from large injection molding machines, utilizing the SUS304 rod to resist corrosive factory environments.
Drives large-scale automotive assembly jigs and heavy component positioning fixtures where precise, high-force linear movement is mandatory.
Selecting this 200 mm bore cylinder is appropriate when application forces exceed the 10053 N push capacity of the 160 mm variant but do not require a custom multi-cylinder rig. If the 185 mm stroke is shorter than your process demands, verify the exact extend length to avoid bottoming out the piston. For this bore size, the operational speed range is 30-500 mm/s.
Because the stroke is under 300 mm, severe rod-bearing bending is less of a concern than with longer strokes, but heavy lateral loads should still be guided externally. Note that the standard adjustable air cushion only decelerates the piston near the end caps; it does not lock or hold the load. If your process requires position holding without live air pressure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder 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 SAI200X185-S is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, provided the port (G3/4) and mounting dimensions match your existing setup.
