The AirTAC AirTAC SAI200X350-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 350mm 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 SAI200X350-S is a double-acting ISO 15552 profile cylinder built for heavy-duty automation. Delivering a formidable 15708 N of push force at 0.5 MPa, it handles massive payloads with ease. The 350 mm stroke provides substantial linear travel for large-scale material handling. This extruded aluminum barrel design eliminates traditional tie-rods, offering a clean exterior that integrates seamlessly into modern machinery.
Equipped with a magnetic piston (-S), this model supports CMSE and DMSE sensor switches dropped directly into the dual side grooves for precise end-of-stroke detection. Standard carbon steel piston rod construction ensures rugged durability, while adjustable air cushions at both ends absorb impact energy. For environments exceeding standard temperature limits, Viton (H) seals are available to maintain performance.

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.
Generates the 21991 N push force at 0.7 MPa required to drive large metal forming and heavy stamping presses.
Actuates large-scale flow gates or heavy diverters on high-capacity bulk material conveyor lines.
Positions heavy chassis components or lifts vehicle subframes during automated automotive assembly processes.
Selecting this 200 mm bore cylinder is appropriate when applications require up to 15708 N of thrust at 0.5 MPa, or a maximum theoretical 3204 kgf at 1.0 MPa. If a project demands less force, stepping down to the 160 mm bore yields 10053 N at 0.5 MPa, which may save space and air consumption. The G3/4 PT port ensures high volumetric flow necessary for rapid piston movement.
Because the 350 mm stroke generates a long unsupported rod extension, side loads can cause severe rod-bearing bending. To prevent premature wear, implement an external guide rail or utilize a guided cylinder variant. Furthermore, the adjustable air cushions only decelerate the piston near the stroke ends; they do not hold loads. If the system loses air pressure, the piston will drift. For true position holding, specify the SAIL locking variant or an external rod lock.
Quick checklist
At 0.5 MPa, the push force is 15708 N and the pull force is 15080 N. If operating at 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X350-S is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile cylinders, matching the 200 mm bore, 350 mm stroke, and G3/4 port interface.
