The AirTAC AirTAC SAI200X140-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 140mm 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 SAI200X140-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations. At 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 140 mm stroke is ideal for robust pressing, lifting, and clamping tasks.
This variant features a SUS304 stainless steel piston rod for superior corrosion resistance, a PT tapered port thread, and a built-in magnet (-S) for seamless integration with CMSE and DMSE reed switches. The extruded aluminum barrel includes sensor grooves on both sides, and adjustable air cushions at both ends absorb high impact energies.

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 immense 15708 N push force required for forming and stamping thick metal sheets in automotive and structural fabrication.
Actuates heavy molds and demolding mechanisms on large-scale injection molding machines, utilizing its 140 mm stroke for reliable extraction.
Drives robust lift tables and heavy-duty conveyor transitions in logistics hubs, moving fully loaded pallets with precise control.
With a 200 mm bore, this cylinder outputs a theoretical maximum force of 3204 kgf at 1.0 MPa. If your application requires less force, stepping down to a 160 mm bore yields 10053 N of push force at 0.5 MPa, which may save space and air consumption.
For installations that must maintain position during a pressure loss or valve centering, note that the standard SAI piston will drift. In such cases, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 units of the same bore and stroke.
Quick checklist
The SAI200X140-S cylinder delivers a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X140-S includes a built-in magnet (-S) and features sensor grooves on both sides of the barrel, making it fully compatible with AirTAC CMSE and DMSE series reed switches.
