The AirTAC AirTAC SAI200X50-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 50mm 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 SAI200X50-S is a double-acting ISO 15552 profile cylinder engineered for immense thrust, delivering 15708 N of push force at just 0.5 MPa. Its 50 mm stroke provides rapid, high-force linear movement within a compact footprint, making it ideal for heavy-duty pressing and clamping operations. The extruded aluminum barrel design omits tie rods, offering a clean exterior that matches standardized ISO 15552 mounting dimensions for seamless interchangeability.
This specific configuration includes a built-in magnet (-S) for use with CMSE and DMSE sensor switches, fitting smoothly into the dual sensor grooves machined along both sides of the barrel. The piston rod utilizes standard carbon steel for robust durability, while the PT (tapered) G3/4 port ensures a high-flow, reliable air connection for this 200 mm bore powerhouse.

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 up to 15708 N at 0.5 MPa to drive short-stroke stamping and forming dies in heavy industrial fabrication lines.
Utilizes its 200 mm bore and 50 mm stroke to secure oversized workpieces during machining or welding operations.
Serves as a pneumatic alternative for high-force pressing tasks, providing rapid actuation where full hydraulic systems are impractical.
Choosing this 200 mm bore over the 160 mm variant significantly increases your thrust capacity, jumping from 10053 N to 15708 N at 0.5 MPa. You should select this model when your application requires extreme force over a short distance. Because the stroke is only 50 mm, rod-bearing bending from side loads is minimal, though external guides should still be used to maintain precise linear tracking.
As a true ISO 15552 profile cylinder, this unit serves as a drop-in replacement for any standard 200 mm bore ISO 15552 cylinder, matching the exact footprint, G3/4 PT port, and mounting accessory interfaces (such as LB, FA, and TC). Note that this standard cylinder does not hold position if air pressure is lost; for gravity-drop prevention, consider the SAIL or BSAI locking variants.
Quick checklist
At 0.5 MPa operating pressure, the SAI200X50-S provides a push force of 15708 N and a pull force of 15080 N. It can reach a theoretical maximum of 3204 kgf at 1.0 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 standards. You can drop it in to replace other 200 mm bore profile cylinders using the same mounting accessories and G3/4 port interface.
