The AirTAC AirTAC SAI200X80 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 80mm 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 SAI200X80 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 15708 N at just 0.5 MPa, this 200 mm bore unit is built to move massive loads reliably. The extruded aluminum barrel eliminates protruding tie rods, providing a clean profile while maintaining the standardized ISO 15552 mounting interface for seamless drop-in replacement.
This specific configuration features a robust carbon steel piston rod and PT (tapered) port threads. While this model does not include a magnet for proximity sensing, the barrel retains dual-side sensor grooves for future upgrades. For applications requiring multi-directional clamping without continuous air pressure, consider the related BSAI bidirectional clamp-lock variant.

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 robust 15708 N push force required to actuate large mechanical stamping presses and form thick gauge steel components.
Generates reliable extraction force to push heavy molded plastic parts out of large industrial injection molds during automated cycles.
Shifts fully loaded heavy-duty pallets or industrial totes along conveyor lines where extreme pushing power is a necessity.
Selecting this 200 mm bore cylinder is ideal when you need immense thrust that smaller bores cannot provide, such as stepping up from a 160 mm bore (which yields 10053 N at 0.5 MPa). The 80 mm stroke keeps the rod bearing stress low, but always verify side-load limits. If your machinery requires true position holding upon air loss, do not rely on the adjustable air cushions—they only decelerate the piston near stroke end. Instead, integrate an external pilot-operated check valve or specify the SAIL variant with an air-released lock.
Ensure your replacement matches these exact parameters: 200 mm bore, 80 mm stroke, G3/4 ports, and a compatible mounting accessory (such as a TC trunnion or LB foot). Specify the -S suffix if you later require embedded magnets for CMSE or DMSE sensor switches.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X80 cylinder provides a push force of 15708 N and a pull force of 15080 N. At the maximum operating pressure of 1.0 MPa, the theoretical maximum force is 3204 kgf.
Yes, the SAI200X80 is a genuine ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions are standardized. It is designed to be dimensionally interchangeable with other ISO 15552 profile cylinders, provided you match the G3/4 port size and mounting accessories.
