The AirTAC AirTAC SAI200X425-S 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-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial 15708 N push force at 0.5 MPa, this 200 mm bore actuator handles high-load tasks with ease. The 425 mm stroke provides extensive linear travel for large-scale machinery.
Equipped with a standard carbon steel piston rod and a built-in magnet, this unit seamlessly integrates CMSE or DMSE sensor switches along the dual-sided extruded aluminum barrel grooves. The PT tapered port threads ensure a robust, leak-free pneumatic connection in demanding industrial environments.

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 required to actuate large forming presses and heavy-duty stamping equipment in metalworking facilities.
Utilizes its 425 mm stroke to push heavy pallets or oversized assemblies across wide transfer lines and heavy-duty conveyor systems.
Deploys the robust carbon steel rod to shift substantial injection molds or die sets into position on large manufacturing platforms.
Selecting this 200 mm bore actuator makes sense when 160 mm bore cylinders (providing 10053 N at 0.5 MPa) lack the necessary thrust for your heaviest payloads. Because the 425 mm stroke creates a long unsupported rod extension, it is highly susceptible to bending under side loads; always utilize an external guide rail or a dedicated guided cylinder to prevent rod-bearing damage.
For applications requiring the piston to maintain its position after air pressure is removed or exhausted, note that the standard adjustable air cushions only decelerate the rod at stroke ends and do not function as a brake. In such scenarios, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model is dimensionally interchangeable per ISO 15552, offering a direct drop-in replacement for other standard profile cylinders when matching the 200 mm bore, 425 mm stroke, G3/4 port, and mounting accessories.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X425-S is a true ISO 15552 profile cylinder, making its mounting interface dimensionally interchangeable with other standard actuators. Ensure your setup matches the 200 mm bore, 425 mm stroke, G3/4 port, and desired mounting accessory.
