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 operations. It provides a substantial push force of 15708 N at 0.5 MPa and a pull force of 15080 N. The 185 mm stroke is a made-to-order length, offering tailored motion control for specialized high-tonnage machinery.
This variant includes a built-in magnet for proximity sensing, seamlessly supporting CMSE and DMSE switches mounted directly into the extruded aluminum barrel grooves. It features a standard carbon steel piston rod and utilizes adjustable air cushions at both ends to smoothly decelerate the massive 200 mm piston.

Provides the immense 15708 N thrust required to actuate large mechanical presses and form thick gauge metal components securely.
Shifts and positions heavy injection molds or tooling plates within industrial machinery, utilizing the precise 185 mm stroke.
Drives robust clamping and positioning fixtures on automotive production lines where high force and reliable CMSE sensor feedback are critical.
Selecting this 200 mm bore is ideal when the 160 mm class (providing 10053 N at 0.5 MPa) cannot generate enough thrust. Even though the 185 mm stroke is non-standard, it remains under the 300 mm threshold, minimizing rod-bearing bending risks. However, for any lateral loads, external guide rails are recommended.
This model uses a G3/4 PT tapered port and is dimensionally interchangeable with other ISO 15552 mounting interfaces. Note that standard air cushions only decelerate the piston; they do not hold a load. If your application requires true position holding without air pressure, consider the BSAI bidirectional clamp-lock variant.
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, the SAI200X185-S is a genuine AirTAC profile cylinder built to the ISO 15552 standard. It is dimensionally interchangeable with other ISO 15552 cylinders, allowing for a seamless drop-in replacement using standard mounting accessories.
