The AirTAC AirTAC SAI200X650-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 650mm 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 SAI200X650-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a robust push force of 15708 N at just 0.5 MPa. Its 650 mm stroke provides the extended travel distance necessary for large-scale material handling and heavy automation. Built with an extruded aluminum barrel, this tie-rod-less design ensures a standardized mounting interface for seamless integration.
This specific configuration includes a SUS304 stainless steel piston rod (option B) for superior corrosion resistance in harsh environments. It features PT tapered port threads and comes equipped with a magnet (-S) to seamlessly integrate CMSE or DMSE electronic sensor switches along the dual barrel grooves for precise end-of-stroke detection.

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 15708 N push force at 0.5 MPa required to actuate large presses and heavy-duty metal forming machinery over long travel distances.
Drives large-scale lifting and positioning fixtures on automotive assembly lines, utilizing the 650 mm stroke and SUS304 rod for reliable, corrosion-resistant operation.
Handles heavy palletized goods in automated distribution centers, where the integrated magnet allows external CMSE sensors to sequence high-load transfer gates.
With a massive 3204 kgf maximum theoretical force at 1.0 MPa, stepping down to the 160 mm bore (10053 N at 0.5 MPa) is advisable if your application requires less energy and a smaller footprint. Because this model features a 650 mm stroke, the extended unsupported rod is highly susceptible to bending under side loads. Utilizing an external guide rail or a fully guided cylinder is strongly recommended to prevent premature rod-bearing wear.
For applications requiring position holding or drop prevention when air pressure is exhausted or valves are centered, remember that the standard adjustable air cushions only decelerate the piston near stroke ends. They do not act as a brake. For fail-safe load holding, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders, allowing a straightforward drop-in replacement using the existing 200 mm bore, 650 mm stroke, PT G3/4 ports, and appropriate mounting accessories like a TC trunnion.
Quick checklist
The SAI200X650-S generates a push force of 15708 N and a pull force of 15080 N at 0.5 MPa. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X650-S is a genuine ISO 15552 profile cylinder, making its mounting dimensions fully interchangeable with other ISO 15552 cylinders. Ensure your setup matches the 200 mm bore, 650 mm stroke, and G3/4 port size.
