The AirTAC SAI63 Standard Cylinder SAI63BX475 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 475mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.
The AirTAC SAI63X475 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. With a 475 mm stroke, it is tailored for automated machinery requiring substantial reach and reliable linear motion. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical debris buildup.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in harsh or washdown environments. It utilizes PT tapered port threads and lacks a piston magnet, meaning it is optimized for pure mechanical actuation rather than electronic position sensing.

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.
Drives extended pushers or diverter arms over long 475 mm cycles on packaging and sorting lines.
Actuates large jigs or clamping fixtures where a 1559 N force at 0.5 MPa is required to seat components.
Moves cutting heads or press blocks through lengthy strokes, leveraging the SUS304 rod to resist dusty and humid environments.
Stepping up to the 80 mm bore yields 2513 N at 0.5 MPa if your application demands higher thrust, while dropping to a 50 mm bore reduces force to 982 N for lighter payloads. At 475 mm of stroke, the unsupported rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external guide rail or use a dedicated guided cylinder.
This model mounts via standard ISO 15552 interfaces and accepts accessories like FA flanges or TC trunnions. Remember that the adjustable air cushions only decelerate the piston near stroke ends; they do not lock the load. If your process requires position holding without live air pressure, select the SAIL variant with an air-released lock or use an external rod lock.
Quick checklist
At 0.5 MPa, the push force is 1559 N and the pull force is 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X475 is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other standard profile cylinders with identical mounting dimensions.
