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 double-acting ISO 15552 profile cylinder engineered for heavy-duty automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200mm bore actuator is built to move massive loads reliably. The 350mm stroke provides ample travel for large-scale material handling and press operations. Its extruded aluminum barrel design omits traditional tie rods, resulting in a rigid yet streamlined profile.
This specific configuration features a robust carbon steel piston rod and PT tapered port threads. Because it lacks a built-in magnet, position sensing requires external methods. For environments requiring exceptional heat resistance, the standard TPU seals can be swapped for Viton (H) options. If your machinery needs multi-directional clamping under pressure, consider the related BSAI bidirectional clamp-lock variant.

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 kinetic energy and 15708 N thrust required to drive large press tools and form thick metal sheets in primary fabrication lines.
Actuates heavy structural clamps and positioning fixtures on vehicle frames, utilizing the 350mm stroke to clear large workpieces during robotic loading.
Shifts heavy pallets or bulk material diverters on high-capacity conveyors, where the robust 200mm bore ensures consistent movement despite high friction loads.
Selecting this 200mm bore actuator means your application requires nearly 16 kN of thrust at 0.5 MPa, stepping up significantly from the 10053 N provided by the 160mm bore. The 350mm stroke is fully supported within the standard maximum of 1500 mm for this bore size. Operating speed ranges from 30-500 mm/s, which is optimal for moving heavy masses safely.
Because this model features a 350mm stroke, the extended rod is susceptible to bending under side loads. Implementing an external guide rail or utilizing a fully guided cylinder is highly recommended to protect the rod bearing from premature wear. Furthermore, a standard SAI cylinder cannot hold a load if air pressure drops; the piston will drift. For fail-safe drop prevention, integrate the SAIL variant with an air-released lock or an external rod lock. As a drop-in replacement, it matches ISO 15552 mounting dimensions, utilizing a G3/4 port and compatible TC or FA mounting accessories.
Quick checklist
At an operating pressure of 0.5 MPa, the SAI200X350 delivers a push force of 15708 N and a pull force of 15080 N. At 0.7 MPa, the push force increases to 21991 N.
Yes, the SAI200X350 is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing machinery designed for ISO 15552 profile cylinders by matching the 200mm bore, 350mm stroke, and G3/4 port size.
