The AirTAC AirTAC SAI200X350 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 is a heavy-duty double-acting profile cylinder built to ISO 15552 dimensional standards. Delivering a substantial 15708 N push force at 0.5 MPa, this 200 mm bore unit is engineered for massive industrial loads. The 350 mm stroke provides ample travel for large-scale material handling. This configuration features a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments.
Fluid control is managed via PT tapered port threads, and the extruded aluminum barrel incorporates dual sensor grooves. Because this variant lacks the -S magnet suffix, it operates without integrated position sensing. For applications requiring pneumatic locking upon pressure loss, consider the related BSAI bidirectional clamp-lock series, as the standard adjustable air cushions only decelerate the piston at stroke ends.

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 for pressing, stamping, and forming thick metal components in automated fabrication lines.
Utilizes the 350 mm stroke to actuate large platens and secure heavy machinery housings during high-torque fastening operations.
Powers heavy-duty diverters and pushers on conveyor systems handling palletized goods or bulk aggregate materials.
Selecting this 200 mm bore cylinder is appropriate when 15708 N of thrust at 0.5 MPa is required, which is a significant step up from the 10053 N provided by the 160 mm bore size. If your application demands less force, stepping down reduces air consumption and physical footprint. The 350 mm stroke requires careful mounting to prevent rod-bearing bending; always use external guides or a guided cylinder carriage to manage side loads and prevent premature seal wear.
This model is dimensionally interchangeable with other ISO 15552 cylinders, allowing a direct drop-in replacement using standard mounting accessories like TC trunnion or FA flange brackets. Remember that a standard SAI does not hold its position if air pressure is exhausted; the piston will drift. Always use external mechanical locks or pilot-operated check valves if failing downward poses a safety hazard.
Quick checklist
At 0.5 MPa operating pressure, this 200 mm bore cylinder generates 15708 N of push force and 15080 N of pull force. At 0.7 MPa, the push force increases to 21991 N.
No, the standard SAI cylinder will drift or drop if air pressure is lost. The adjustable air cushions only decelerate the piston at the end of the stroke. For position holding, you must use an external rod lock, a pilot-operated check valve, or the related SAIL/BSAI locking cylinder variants.
