The AirTAC AirTAC SAI200X125 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 125mm 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 SAI200X125 is a robust double-acting profile cylinder engineered to ISO 15552 dimensional standards, ensuring seamless drop-in compatibility with any equivalent ISO 15552 mounting interface. Operating at 0.15-1.0 MPa, it generates a substantial 15708 N of push force and 15080 N of pull force at 0.5 MPa, making it ideal for heavy-duty industrial pressing and lifting over its 125 mm stroke.
Beyond the standard specifications, this model features a carbon steel piston rod for high tensile strength under heavy loads. The extruded aluminum barrel includes integrated sensor grooves on both sides, allowing direct mounting of CMSE or DMSE switches when a magnet is specified. For environments exceeding standard thermal limits, Viton (H) seals can be selected to withstand higher operating temperatures.

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 pressing force needed to form thick metal components and execute heavy-duty stamping operations reliably.
Secures large industrial injection molds utilizing its massive 200 mm bore output and robust carbon steel rod construction.
Drives high-tonnage compaction rams for dense waste or material processing, benefiting from adjustable end-cushioning to stop heavy masses smoothly.
Selecting this 200 mm bore cylinder is appropriate when applications require maximum thrust exceeding 15000 N at 0.5 MPa; stepping down to a 160 mm bore reduces the push force to 10053 N. The PT (tapered) G3/4 porting matches the high air volume required to move the large piston efficiently within its 30-500 mm/s speed range. Standard mounting accessories include TC trunnion and FA flange options.
Because the 125 mm stroke is relatively short for this massive bore, rod-bearing bending is minimal, but external guides are still recommended if absorbing offset loads. Note that the standard adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If static position holding is required without live air pressure, specify the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X125 cylinder provides a theoretical push force of 15708 N and a pull force of 15080 N. At the maximum rated pressure of 1.0 MPa, it can deliver up to 3204 kgf of force.
Yes, the SAI200X125 is a genuine AirTAC profile cylinder built to the exact ISO 15552 mounting interface standards. It is dimensionally interchangeable with other ISO 15552 cylinders of the same bore size, utilizing a G3/4 PT port and standard mounting accessories.
