The AirTAC AirTAC SAI200X325-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 325mm 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 SAI200X325-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. It generates a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving large masses over its 325 mm stroke. As a tie-rod-less extruded aluminum design, it provides a clean, standardized mounting interface that drops directly into existing ISO 15552 machinery footprints.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance in harsh environments. Equipped with a magnet (-S), it supports CMSE and DMSE sensor switches via the dual grooves machined into the barrel. Operating at speeds of 30-500 mm/s, it features adjustable air cushions at both ends to decelerate the massive payload smoothly.

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 15708 N push force at 0.5 MPa required to actuate large mechanical stamping presses and heavy-duty forming dies.
Shifts heavy injection molds or industrial tooling along the 325 mm stroke, utilizing the SUS304 rod to resist corrosive shop environments.
Drives massive pneumatic diverter gates on high-capacity mining or aggregate conveyors where high impact forces are routine.
Selecting this 200 mm bore cylinder is appropriate when application forces exceed the 10053 N push capability of the 160 mm bore variant but do not require a custom multi-stage solution. Because the 325 mm stroke exceeds 300 mm, the extended rod is highly susceptible to bending under side loads. You must use an external guide rail or a dedicated guided cylinder to prevent rod-bearing damage and premature seal wear.
This model uses G3/4 PT tapered ports and can be mounted using FA, FB, LB, CA, CB, or TC accessories. If the machinery loses air pressure, the standard SAI cylinder cannot hold a load in place; the piston will drift. For vertical applications requiring fail-safe position holding without live air pressure, specify the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock cylinder.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X325-S is dimensionally interchangeable per ISO 15552. It shares standardized mounting dimensions with other ISO 15552 profile cylinders, allowing it to serve as a drop-in replacement without modifying the machine frame.
