The AirTAC AirTAC SAI200X35-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 35mm 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 SAI200X35-S is a double-acting ISO 15552 profile cylinder engineered for extreme force tasks, delivering a substantial 15708 N of push force at just 0.5 MPa. Equipped with a 35 mm stroke and a G3/4 port, this unit is built to move heavy masses over short distances with immediate authority. The extruded aluminum barrel design omits traditional tie-rods, offering a sleek, integrated profile that simplifies cleaning and maintenance.
This specific configuration includes a standard carbon steel piston rod and a built-in magnet (-S) for seamless integration with CMSE and DMSE sensor switches. The barrel features sensor grooves on both sides, allowing flexible switch mounting. For environments requiring elevated thermal stability, the standard TPU seals can be swapped for Viton (H) variants to handle higher operating temperatures.

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 to operate short-stroke stamping and forming presses for thick gauge metals.
Delivers rapid, high-force ejection of large molded plastic components from heavy industrial presses within a compact 35 mm stroke.
Secures heavy structural steel or large cast components during machining operations, utilizing its extreme clamping force over a short travel distance.
Selecting this 200 mm bore model is appropriate when the 160 mm bore (yielding 10053 N at 0.5 MPa) is insufficient for your load requirements. Because the 35 mm stroke is very short, side-load stress on the rod bearing is minimal, though you should still ensure axial alignment to prevent premature wear. If your machinery demands position holding without continuous air pressure, the standard SAI cylinder will drift upon pressure loss; consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants for secure load retention.
As a genuine ISO 15552 cylinder, it provides exact dimensional interchangeability with other ISO 15552 profile cylinders, serving as a drop-in replacement for standardized mounting setups. When ordering, confirm the required mounting accessories (such as CA/CB clevis or TC trunnion), the PT tapered port thread, and the necessary CMSE/DMSE sensor switches to complete your assembly.
Quick checklist
At a standard operating pressure of 0.5 MPa, the SAI200X35-S generates a push force of 15708 N. At the maximum rated pressure of 1.0 MPa, the theoretical force reaches 3204 kgf.
Yes, the SAI200X35-S includes a standard magnet (-S) and features dual sensor grooves on the extruded aluminum barrel, making it fully compatible with AirTAC CMSE and DMSE series reed switches.
