The AirTAC AirTAC SAI200X45-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 45mm 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 SAI200X45-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty operations, delivering a robust push force of 15708 N at 0.5 MPa. Its 45 mm stroke is optimal for short-travel, high-force clamping and pressing tasks. As a genuine AirTAC component, it ensures reliable performance in demanding industrial environments.
This specific configuration features a SUS304 stainless steel rod (material code B) for superior corrosion resistance, making it highly suitable for moist or chemically active settings. It includes a built-in magnet (-S) that integrates seamlessly with CMSE and DMSE sensor switches via the dual-side grooves on the extruded aluminum barrel. Additionally, the PT tapered port threads guarantee a tight, leak-free pneumatic connection.

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 force needed for short-stroke metal stamping, forming, and riveting operations in fabrication plants.
Secures large molds or heavy workpieces during machining, utilizing the 45 mm stroke for rapid and powerful holding cycles.
Drives short-travel hydraulic-free press mechanisms where consistent 0.5 MPa actuation force is required for assembly tasks.
Selecting this 200 mm bore model is appropriate when the 160 mm bore variant, which provides 10053 N of push force at 0.5 MPa, is insufficient for your load requirements. The 45 mm stroke is highly effective for short, powerful movements. Because the stroke is well under the 300 mm threshold, rod-bearing bending is not a significant concern, though the immense output force necessitates a rigidly mounted framework.
For applications requiring the load to be held securely in place without continuous air pressure, note that the standard SAI does not function as a locking device. The adjustable air cushions at both ends only decelerate the piston near the stroke limits to prevent impact damage. If true position holding is required, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To replace an existing unit, match the 200 mm bore, 45 mm stroke, G3/4 PT ports, and ensure compatibility with your chosen mounting accessory, such as an FA flange or CA clevis.
Quick checklist
The SAI200X45-S cylinder generates a push force of 15708 N and a pull force of 15080 N when operated at 0.5 MPa.
Yes, the SAI200X45-S is dimensionally interchangeable per ISO 15552 standards, allowing it to serve as a drop-in replacement for other ISO 15552 profile cylinders with matching 200 mm bore and 45 mm stroke specifications.
