The AirTAC AirTAC SAI200X552 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 552mm 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 SAI200X552 is a heavy-duty, double-acting profile cylinder built to the ISO 15552 standard, making it a dimensionally exact drop-in replacement for other ISO 15552 profile cylinders. Delivering massive thrust, it provides 15708 N of push force and 15080 N of pull force at 0.5 MPa, scaling up to 21991 N push at 0.7 MPa. The 552 mm stroke is well-suited for moving large masses over extended linear distances in heavy industrial machinery.
Beyond the standard specifications, this configuration features a robust carbon steel piston rod and PT tapered port threads for a secure, leak-free pneumatic connection. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE series switches if position feedback is later required.

Provides the high kinetic energy and 15708 N baseline thrust required to actuate large presses, stamping dies, and heavy-gauge metal forming machinery.
Handles heavy chassis components and positions large automotive subframes along extended 552 mm travel distances during automated welding and bolting sequences.
Drives massive diverter gates and heavy-duty bulk material routing doors in mining, aggregate, and heavy logistics conveyor systems.
With a 200 mm bore generating 15708 N at just 0.5 MPa, stepping down to a 160 mm bore reduces the push force to 10053 N, which may be insufficient for heavy payloads. Conversely, if the application requires even more power, you must evaluate external load structures as this is the largest standard SAI bore. Because the 552 mm stroke creates a long unsupported rod extension, side loads will cause severe bending stress on the rod bearing; an external guide rail or a fully guided cylinder is strongly recommended to prevent premature seal wear.
This model uses a G3/4 port and a standard 552 mm stroke within the 1500 mm maximum limit. It is a direct dimensional match for any ISO 15552 mounting accessory, including FA foot brackets or TC trunnion joints. Note that a plain double-acting cylinder loses all holding force and drifts downward when air pressure is removed; if the load must remain safely suspended during an exhaust or e-stop event, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve.
Quick checklist
At a standard operating pressure of 0.5 MPa, the 200 mm bore generates 15708 N of push force and 15080 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
Yes, the SAI200X552 is a genuine ISO 15552 profile cylinder, meaning its mounting dimensions, bolt patterns, and G3/4 port locations are fully interchangeable with any other cylinder built to the same ISO 15552 standard.
