The AirTAC AirTAC SAI200X250-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 250mm 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 SAI200X250-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200mm bore actuator handles high-thrust tasks with ease. The 250mm stroke provides ample extension for large-scale pressing, lifting, and clamping operations.
This model includes a magnetic piston (-S) for seamless integration with CMSE or DMSE position sensors along the dual grooves of the extruded aluminum barrel. It features a robust carbon steel piston rod and PT tapered G3/4 ports. For applications requiring extreme heat, the standard TPU seals can be swapped for Viton (H) options, ensuring reliability across the -20 to +70 C operating range.

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 at 0.5 MPa required for stamping, bending, and forming thick metal sheets in automotive and fabrication plants.
Acts as the main actuator in automated hydraulic press lines, utilizing its 250mm stroke to drive heavy tooling with consistent cycle times.
Secures massive workpieces or molds during machining, relying on the robust carbon steel rod to withstand high side loads when properly guided.
Select this 200mm bore actuator when your application requires massive force that smaller bores cannot provide, such as replacing a 160mm cylinder that only offers 10053 N at 0.5 MPa. The 250mm stroke is well within standard parameters, but always verify that your mounting configuration—whether using FA flanges or TC trunnion brackets—can support the cylinder's substantial weight and dynamics.
Because this is a double-acting cylinder, it relies on continuous air pressure to maintain its position; if air is lost or exhausted, the piston will drift. For loads that must be held securely during pressure drop scenarios, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder. As a true ISO 15552 profile cylinder, it offers a drop-in replacement for any matching 200mm bore ISO 15552 interface.
Quick checklist
At an operating pressure of 0.5 MPa, this 200mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder is double-acting and will drift if air pressure is lost. The adjustable air cushions only decelerate the piston at stroke ends. For fail-safe load holding, you should use the SAIL lock variant or an external rod lock.
