The AirTAC Airtac SAI200 Standard Cylinder SAI200AX250S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 250mm 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 SAI200X250-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a theoretical push force of 15708 N at 0.5 MPa and a maximum of 3204 kgf at 1.0 MPa, this 200 mm bore unit handles massive loads. The 250 mm stroke provides robust linear movement for large-scale pressing and lifting tasks.
This variant includes a magnet for CMSE and DMSE sensor switches, fitting neatly into the dual grooves on the extruded aluminum barrel. It features an SUS420J2 stainless steel piston rod for superior corrosion resistance and utilizes PT tapered port threads. The adjustable air cushions at both ends decelerate the heavy piston smoothly, operating efficiently at speeds of 30-500 mm/s.

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 required to form and stamp thick sheet metal components in automated fabrication lines.
Delivers steady, high-tonnage force to seat large bearings or heavy machinery components into housings without shock damage.
Drives heavy-duty lifting and positioning mechanisms for fully loaded industrial pallets in high-capacity logistics hubs.
Selecting this 200 mm bore cylinder is ideal when your application requires extremely high thrust that smaller bores cannot provide, such as replacing twin 125 mm cylinders (which offer 6136 N each at 0.5 MPa) with a single, more powerful actuator. If your force requirements are lower, stepping down to a 160 mm bore reduces the push force to 10053 N while saving physical envelope space.
Because the 250 mm stroke is substantial, carefully manage side loads to prevent rod-bearing bending; utilize an external guide rail or a guided cylinder design for optimal longevity. Note that this standard SAI cylinder will drift if air pressure is lost, as the adjustable cushions only decelerate the piston near stroke end and do not lock the load. For position holding without live pressure, consider the BSAI clamp-lock variant. As a true ISO 15552 profile cylinder, it offers a drop-in replacement for any matching 200 mm bore, 250 mm stroke, G3/8 port interface with an LB foot or TC trunnion mount.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder provides a push force of 15708 N and a pull force of 15080 N. At its maximum rated pressure of 1.0 MPa, it can deliver a theoretical force of 3204 kgf.
Yes, the SAI200X250-S is a genuine ISO 15552 profile cylinder, making it dimensionally interchangeable with other standard ISO 15552 cylinders of the same bore and stroke. You can use it as a drop-in replacement by matching the G3/8 port and standard mounting accessories.
