The AirTAC AirTAC SAI200X120 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 120mm 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 SAI200X120 is a heavy-duty double-acting profile cylinder engineered to ISO 15552 dimensional standards, ensuring seamless interchangeability with other compliant global manufacturers. Delivering a robust push force of 15708 N at 0.5 MPa, this 200 mm bore unit is built for high-load industrial tasks.
This specific configuration features a SUS304 stainless steel piston rod (option B) for superior corrosion resistance and includes PT tapered port threads. While the standard extruded aluminum barrel lacks a magnet, adjustable air cushions at both ends manage end-of-stroke impact energy for this massive moving mass.

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 thrust required to operate large mechanical presses and form thick gauge metal components.
Actuates massive structural welding fixtures and positions heavy chassis frames with reliable clamping power.
Drives large-scale deflector gates on heavy-duty conveyors to route dense aggregates or bulk steel stock.
Select this 200 mm bore actuator when 160 mm (10053 N push at 0.5 MPa) cannot overcome your process resistance, as the step up to 200 mm nearly doubles the available thrust. For applications requiring position holding without constant air pressure, remember that standard pneumatic cushions only decelerate the piston and will not prevent drift; integrate an external rod lock or specify the SAIL variant for fail-safe braking needs.
When replacing an existing ISO 15552 cylinder, match the 200 mm bore, 120 mm stroke, G3/4 PT port, and required mounting accessories like TC trunnion or FA flange brackets. Because the stroke is under 300 mm, rod bearing bending is minimal, but always verify axial alignment to prevent premature seal wear.
Quick checklist
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. If you operate at 0.7 MPa, the push force increases to 21991 N.
Yes. The SAI200X120 is a true ISO 15552 profile cylinder, meaning its mounting dimensions are fully interchangeable with other ISO 15552 compliant actuators of the same bore size.
