The AirTAC AirTAC SAI200X325 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 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty linear motion. It generates a substantial 15708 N of push force at 0.5 MPa and 21991 N at 0.7 MPa, making this 325 mm stroke unit ideal for high-thrust pressing and heavy load manipulation.
Built with an extruded aluminum barrel, this model omits traditional tie-rods for a cleaner exterior. It is configured with a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance. Furthermore, 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 21991 N output at 0.7 MPa required for stamping, riveting, and bending thick metal components.
Drives heavy industrial platens over its 325 mm travel to seat large bearings or compress dense materials securely.
Acts as a high-force pneumatic alternative for shop-floor pressing tasks where fluid power systems are impractical.
Selecting this 200 mm bore cylinder is appropriate when application forces exceed the 10053 N push capacity of the 160 mm variant at 0.5 MPa. Because the 325 mm stroke creates a long unsupported rod extension, it is highly susceptible to bending under side loads; utilizing an external guide rail or a guided cylinder module is strongly recommended to prevent rod-bearing damage.
This unit is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 cylinders with matching 200 mm bore, 325 mm stroke, G3/4 PT ports, and compatible mounting accessories like the TC trunnion. Note that if the pneumatic supply is lost, the standard adjustable air cushions only decelerate the piston at stroke ends and will not hold the load; use the SAIL or BSAI locking variants if dead-load holding is required.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder outputs 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
It is dimensionally interchangeable per ISO 15552, meaning it matches the standardized mounting interfaces of other 200 mm bore ISO 15552 profile cylinders. Always verify your specific mounting accessory and port requirements.
