The AirTAC AirTAC SAI200X650 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 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a robust 15708 N push force at 0.5 MPa, this 200mm bore unit is designed to move substantial masses. The 650mm stroke provides the extended travel needed for large clamping, pressing, or lifting tasks. It features a PT tapered port thread and a standard carbon steel piston rod for high structural integrity.
Unlike traditional tie-rod bodies, this extruded aluminum profile barrel integrates sensor grooves on both sides. While this specific configuration omits the magnet, you can easily add position detection by ordering the -S variant to pair with CMSE or DMSE switches. For environments requiring extreme heat resistance, the standard TPU seals can be swapped for Viton (H) options.

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 force at 0.5 MPa necessary to drive large metal forming and stamping presses over a 650mm travel distance.
Actuates large-scale robotic lifting and positioning fixtures for chassis or powertrain components on the production line.
Handles the high kinetic energy of diverting fully loaded heavy-duty pallets across material handling conveyor systems.
This 200mm bore provides 15708 N of thrust at 0.5 MPa; if your load only requires 10053 N, stepping down to the 160mm bore reduces air consumption and physical footprint. Conversely, if you need even more power, there is no larger standard SAI bore. The 650mm stroke is well within the 1500mm maximum standard limit, but strokes of this length require careful mounting to prevent rod-bearing bending under side loads. Always use an external guide rail or a dedicated guided cylinder to support off-center loads.
As a true ISO 15552 profile cylinder, it offers drop-in dimensional interchangeability with other ISO 15552 units. Ensure your setup matches the 200mm bore, 650mm stroke, G3/4 port, and preferred mounting accessory (such as a TC trunnion or LB foot). Remember that standard double-acting cylinders lose position if air pressure drops; for fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants instead of relying on the cushions.
Quick checklist
At a 0.5 MPa operating pressure, this 200mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X650 is a genuine ISO 15552 profile cylinder. It is dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke, provided your setup matches the G3/4 port size and standard mounting interface.
