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 linear motion. Delivering a substantial 15708 N push force at 0.5 MPa and 15080 N pull force, this 200mm bore unit is built to move massive loads efficiently. The 250mm stroke provides the travel distance required for large-scale pressing, lifting, and indexing operations.
Equipped with a -S magnet, this model operates seamlessly with CMSE and DMSE sensor switches fitted into the dual-side grooves of the extruded aluminum barrel. Per your configuration, it features a SUS304 stainless steel piston rod (code B) for superior corrosion resistance, paired with PT tapered port threads. Operating pressure ranges from 0.15 to 1.0 MPa, with adjustable air cushions at both ends to manage the high kinetic energy of this large-bore actuator.

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.
Drives large press dies and stamping fixtures where the 15708 N push force at 0.5 MPa is necessary to deform thick metal sheets.
Applies steady clamping pressure for heavy machinery assembly, utilizing the 250mm stroke to accommodate large workpiece heights.
Actuates massive structural diverters or heavy-duty gates on high-capacity mining or aggregate conveyor lines.
Selecting this 200mm bore actuator is appropriate when applications require forces exceeding 15000 N at just 0.5 MPa. If the load requirements are lower, stepping down to a 160mm bore reduces the push force to 10053 N, saving air volume and physical footprint. Conversely, this SAI200X250-S represents the maximum standard bore in the series, offering a theoretical maximum force of 3204 kgf at 1.0 MPa.
For this 250mm stroke, side-load bending stress on the rod bearing is moderate but should still be evaluated. If the mechanism experiences off-center loads, implement an external guide rail to prevent premature seal wear. This cylinder does not hold its position if air pressure drops; for dead-load holding, integrate the BSAI bidirectional clamp-lock variant or an external pilot-operated check valve. As a true ISO 15552 profile cylinder, it serves as a direct dimensional drop-in replacement for other ISO 15552 actuators of the same bore and stroke, utilizing standard FA, FB, CA, or TC mounting accessories.
Quick checklist
At 0.5 MPa, this 200mm bore cylinder provides 15708 N of push force and 15080 N of pull force. At the maximum operating pressure of 0.9 MPa, the push force increases to 28274 N.
Yes. The SAI200X250-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 standard cylinders of the same bore size. You can use the existing PT port connections and standard mounting accessories.
