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 robust double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial applications. Featuring an extruded aluminum barrel, it provides a standardized mounting interface ensuring dimensional interchangeability with other ISO 15552 actuators. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200mm bore unit paired with a 120mm stroke is built to move massive loads reliably.
Beyond the standard thrust metrics, this model features a carbon steel piston rod for high tensile strength under extreme loads. The standard TPU seals handle typical industrial temperatures, while the barrel includes dual sensor grooves on both sides, allowing flexible placement of CMSE or DMSE switches when a magnet is specified. For applications needing bidirectional clamping under zero pressure, the related BSAI clamp-lock variant offers a secure solution.

Provides the immense 15708 N push force required to form and stamp thick metal sheets in automated fabrication lines.
Acts as the primary actuator in heavy industrial presses, utilizing its 120mm stroke for high-impact short-cycle operations.
Delivers reliable, high-force ejection of large molded parts from heavy machinery, ensuring smooth production flow.
Selecting this 200mm bore actuator provides 15708 N of thrust at just 0.5 MPa, making it the powerhouse of the SAI series. If your application does not require moving extreme masses, stepping down to the 160mm bore yields 10053 N at the same pressure, saving valuable space and air consumption. The PT tapered port threads ensure a tight, leak-free pneumatic connection directly to your air supply.
Because this is a double-acting cylinder, it relies on continuous air pressure to extend and retract the load. If your system loses air pressure or the valve is centered, the piston will drift and drop. The integrated adjustable air cushions at both ends only serve to decelerate the piston near the stroke limits to prevent end-cap impact; they do not lock the load. For fail-safe position holding, consider the SAIL air-released lock variant or an external rod lock. To ensure a true ISO 15552 replacement match, verify the 200mm bore, 120mm stroke, G3/4 port, and required mounting accessory.
Quick checklist
The SAI200X120 generates 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 SAI200X120 is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable as a drop-in replacement for other ISO 15552 standard cylinders with matching 200mm bore and 120mm stroke specifications.
