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 engineered for heavy-duty automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200 mm bore unit is built to move massive loads across its 350 mm stroke. The extruded aluminum barrel omits traditional tie-rods, providing a clean profile while maintaining rigorous dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration includes a SUS304 stainless steel rod (material code B) for superior corrosion resistance in harsh environments. It is equipped with a magnet (-S) to trigger CMSE or DMSE sensor switches housed in the dual side grooves. Fluid ports feature PT tapered threads, and the piston features adjustable air cushions at both ends to decelerate heavy moving masses smoothly.

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 high clamping force needed to secure thick metal plates during heavy industrial stamping and forming operations.
Ejects heavy casted components from molds, utilizing the SUS304 rod to withstand high-temperature, abrasive foundry environments.
Drives robust diverting gates on heavy-duty aggregate or mining conveyors, moving substantial material flows with reliable 350 mm travel.
Selecting this 200 mm bore cylinder is appropriate when application thrust requirements exceed the 10053 N push force generated by the 160 mm bore at 0.5 MPa. Operating speed is rated for 30-500 mm/s, reflecting the controlled pacing needed for large payloads. Because this model features a 350 mm stroke, the extended rod is susceptible to bending under side loads; utilize external guide rails or a guided cylinder carriage to prevent premature rod-bearing wear.
As a standard double-acting actuator, this cylinder relies on continuous air pressure to hold its position. If your workflow drops pressure or centers the valve, the piston will drift. For dead-load holding without live pressure, integrate an external pilot-operated check valve or select the BSAI bidirectional clamp-lock variant. To mount this ISO 15552 unit, choose from FA flange, CA clevis, or TC trunnion accessories, and ensure your pneumatic plumbing matches the G3/4 port.
Quick checklist
At a 0.5 MPa operating pressure, this 200 mm bore cylinder generates a push force of 15708 N and a pull force of 15080 N. At the maximum 1.0 MPa pressure, the theoretical push force reaches 3204 kgf.
Yes, the SAI series is a true ISO 15552 profile cylinder. Its mounting dimensions, G3/4 ports, and 200 mm bore interface are fully interchangeable with other ISO 15552 standard cylinders, allowing for seamless integration without altering your machine footprint.
