The AirTAC AirTAC SAI200X120-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Operating at 0.5 MPa, it generates a substantial push force of 15708 N and a pull force of 15080 N. The 120 mm stroke provides robust linear motion for high-mass handling. Equipped with a -S magnet, this unit supports CMSE and DMSE sensor switches housed in the dual-side grooves of its extruded aluminum barrel.
This model features a standard carbon steel piston rod and utilizes adjustable air cushions at both ends to smoothly decelerate large loads. The pneumatic supply connects via PT tapered threads (G3/4 port). As a genuine AirTAC component, it offers a dimensionally interchangeable ISO 15552 mounting interface, allowing seamless integration into existing heavy machinery frameworks.

Provides the immense 15708 N push force required to actuate large mechanical presses and form thick metal components.
Drives heavy ejection systems out of large injection molding machines, utilizing the dual sensor grooves for precise mold-break confirmation.
Lifts and positions heavy loaded pallets or large bulk containers in automated high-throughput distribution centers.
Select this 200 mm bore actuator when an application requires moving extreme masses that exceed the 10053 N push force of the adjacent 160 mm bore size. For operations needing less than 10000 N of thrust, stepping down to the 160 mm bore saves physical envelope space and compressed air volume. Because this unit includes a magnet (-S), it is fully prepared for position sensing out of the box.
While the 120 mm stroke is relatively short and less prone to bending than longer strokes, the sheer mass moved by this cylinder requires careful load alignment. If a machine loses air pressure, this standard SAI cylinder cannot hold its load and will drift. For gravity-lowering safety, specify the SAIL (air-released lock) variant or integrate an external rod lock.
Quick checklist
At a standard operating pressure of 0.5 MPa, this 200 mm bore cylinder provides 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 SAI200X120-S is a profile cylinder built to the ISO 15552 standard, making its mounting interface dimensionally interchangeable with other ISO 15552 cylinders. It uses a G3/4 PT port and standard mounting accessories.
