The AirTAC AirTAC SAI200X550-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 550mm 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 SAI200X550-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty motion. Operating at 0.5 MPa, it generates a substantial 15708 N of push force and 15080 N of pull force, making it well-suited for high-mass automation tasks requiring a 550 mm stroke.
This specific configuration includes a SUS304 stainless steel piston rod for superior corrosion resistance and a magnetic piston (-S) that interfaces seamlessly with CMSE and DMSE sensors via the dual grooves on the extruded aluminum barrel. It utilizes PT tapered port threads and adjustable air cushions at both ends to manage kinetic energy.

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 necessary to actuate large mechanical presses and form thick gauge metal components reliably.
Moves substantial injection mold tooling or heavy dies across 550 mm of travel using corrosion-resistant SUS304 rod construction.
Powers heavy-duty diverter arms on high-capacity aggregate or ore conveyors where robust kinetic energy absorption is required.
When sizing this 200 mm bore actuator, verify if the 15708 N output at 0.5 MPa exceeds your load requirement, as stepping down to a 160 mm bore yields 10053 N and saves physical space. If your application demands intermediate force, the 160 mm bore might be a more compact alternative.
For a 550 mm stroke, the unsupported piston rod is highly susceptible to bending under side loads, which can rapidly degrade the rod bearing. Utilizing an external guide rail or selecting a guided cylinder module is strongly recommended to prevent premature wear. Furthermore, the adjustable cushion only decelerates the piston; it does not lock the load. If position holding without air pressure is required, integrate an external pilot-operated check valve or specify the SAIL lock variant.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X550-S delivers 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X550-S is dimensionally interchangeable per ISO 15552 profile cylinder standards. It shares the same mounting interface and accessories as other ISO 15552 cylinders, allowing for a drop-in replacement.
