The AirTAC AirTAC SAI200X450-S ISO 15552 Cylinder | 200mm Bore is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø200mm bore and 450mm 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 SAI200X450-S is a double-acting ISO 15552 profile cylinder engineered for heavy-duty industrial automation. It provides a substantial push force of 15708 N and a pull force of 15080 N at 0.5 MPa, making it well-suited for moving massive loads over a 450 mm stroke. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that simplifies the mounting of accessories and sensors.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in harsh environments. It is equipped with a magnet (-S) for direct compatibility with CMSE and DMSE sensor switches, which seat neatly into the dual grooves machined into the barrel profile. The fluid ports feature PT tapered threads, and the cylinder incorporates adjustable air cushions at both ends to decelerate the massive 200 mm piston smoothly.

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 tonnage push force necessary to actuate large stamping presses and heavy-gauge metal forming dies.
Shifts and positions heavy injection molds or die sets within automated manufacturing cells over its 450 mm stroke.
Powers heavy-duty diverter arms and large-scale sorting gates handling dense bulk materials on primary conveyor lines.
Selecting this 200 mm bore cylinder is appropriate when application thrust requirements exceed the 10053 N push force of the 160 mm bore variant but fall within the 15708 N capacity at 0.5 MPa offered by this model. Operating speed ranges from 30-500 mm/s. Because this unit features a 450 mm stroke, the extended unsupported piston rod is susceptible to bending under side loads. To prevent premature rod-bearing wear or seal failure, use an external linear guide or a guided cylinder carriage to absorb lateral forces.
This model serves as a dimensionally interchangeable drop-in replacement for other ISO 15552 profile cylinders, matching standardized mounting dimensions for FA/FB flanges, CA/CB clevises, and TC trunnion brackets. Note that the integrated air cushions only decelerate the piston at stroke ends; they do not hold a load. If the machinery requires a fail-safe position hold upon loss of air pressure, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of the standard SAI.
Quick checklist
At an operating pressure of 0.5 MPa, this 200 mm bore cylinder generates 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 SAI200X450-S is dimensionally interchangeable per ISO 15552 standards. It shares identical mounting interface dimensions with other ISO 15552 profile cylinders, allowing it to serve as a drop-in replacement when matching the 200 mm bore, 450 mm stroke, and PT port configuration.
