The AirTAC AirTAC SAI200X105 ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 105mm 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 SAI200X105 is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. Delivering a substantial push force of 15708 N at 0.5 MPa, this 200 mm bore unit is built to move large masses reliably. Its extruded aluminum barrel design omits traditional tie rods, providing a clean profile while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
This specific configuration features a standard carbon steel piston rod and PT (tapered) port threads. Because it lacks a built-in magnet, it does not natively support reed or solid-state sensors; if position feedback is required, you would specify the -S variant to equip the dual sensor grooves machined into both sides of the barrel for CMSE or DMSE switches.

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 massive 15708 N push force required to actuate large press brakes or heavy stamping dies at 0.5 MPa operating pressure.
Drives large-scale diverter arms on mining or aggregate conveyors, where the 200 mm bore easily overcomes the friction of heavy bulk materials.
Secures oversized injection molds or heavy tooling plates during processing, utilizing the cylinder's rigid profile barrel and 105 mm stroke.
Selecting this 200 mm bore cylinder is appropriate when your application demands extreme thrust that smaller bores cannot provide, such as stepping up from a 160 mm bore (which offers 10053 N push at 0.5 MPa). With a 105 mm stroke, the rod extension is relatively short, minimizing side-load bending stresses on the rod bearing compared to longer strokes.
Ensure your mounting interface matches the ISO 15552 standard footprint, utilizing compatible accessories like TC trunnion or LB foot brackets. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold a load. If the machinery loses air pressure, the cylinder will drift, so integrate an external rod lock or a SAIL/BSAI variant for fail-safe position holding.
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. If pressure is increased to 0.7 MPa, the push force rises to 21991 N.
Yes, the SAI200X105 is dimensionally interchangeable per ISO 15552 standards, meaning it matches the mounting interface and port locations of other ISO 15552 profile cylinders. It uses a G3/4 port and operates at speeds between 30-500 mm/s.
