The AirTAC AirTAC SAI200X425 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 425mm 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 SAI200X425 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty applications requiring immense thrust. It generates 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it well-suited for demanding industrial pressing and lifting tasks over a 425 mm travel distance.
This model features a robust carbon steel piston rod and utilizes PT tapered port threads for secure pneumatic connections. For environments experiencing elevated ambient heat, the standard TPU seals can be swapped for high-temperature Viton (H) elastomers to ensure continuous, reliable operation.

Provides the robust 15708 N push force required to form and stamp thick metal components in automated fabrication lines.
Executes high-tonnage pressing and riveting operations where consistent force across a 425 mm stroke is mandatory.
Actuates heavy-duty diverter arms to redirect massive fabricated parts or palletized goods on robust conveyor systems.
Select this 200 mm bore actuator when your machinery requires substantial force that exceeds the 10053 N push capacity of the 160 mm variant at 0.5 MPa. If the 425 mm stroke provides more travel than necessary, stepping down to the 160 mm bore can also reduce overall footprint and air consumption.
Because the 425 mm stroke creates a long unsupported rod extension, it is highly susceptible to bending under side loads. Implement an external guide rail or utilize a guided cylinder configuration to prevent rod-bearing damage. Note that this standard cylinder relies on air pressure to maintain its position; if pneumatic supply is lost, the load will drift. For fail-safe holding requirements, specify the BSAI clamp-lock or SAIL locking variant.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. The maximum theoretical force at 1.0 MPa is 3204 kgf.
Yes, the SAI200X425 is a true ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other ISO 15552 compliant actuators. Ensure your setup matches the G3/4 port and utilizes appropriate mounting accessories like the TC trunnion.
