The AirTAC Airtac SAI63 Standard Cylinder SAI63AX150 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø63mm bore and 150mm stroke, G3/8 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 SAI63X150 is a double-acting ISO 15552 profile cylinder offering a practical 150mm stroke. It generates 1559N of push force at 0.5MPa, making it a robust choice for medium-duty automation. The extruded aluminum barrel design omits tie rods, providing a clean exterior that drops right into existing ISO 15552 mounting interfaces.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid environments. It uses PT tapered port threads and, because no magnet is specified, is optimized purely for mechanical actuation without sensor tracking.

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 reliable 1559N clamping force at 0.5MPa for holding medium-sized metal castings during CNC machining operations.
Actuates a diverter arm across a 150mm stroke to route packages on a high-speed packaging line.
Supplies steady downward pressure for light assembly presses, fitting bearings or pins into housings.
Choose the 63mm bore when 50mm falls short—its 1559N push force at 0.5MPa comfortably outmuscles the 982N of the SAI50. If your application requires less force, stepping down to a 40mm bore yields 628N and saves space. At 150mm stroke, side-load stress is minimal, but always ensure rigid mounting to prevent rod-bearing wear.
If the machine loses air pressure, this cylinder cannot hold a load vertically; the piston will drift. Use the SAIL variant with an air-released lock or an external pilot-operated check valve for fail-safe holding. This model is dimensionally interchangeable with other ISO 15552 cylinders, requiring a G3/8 port, standard mounting accessories, and no magnet.
Quick checklist
At 0.5MPa, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At the maximum operating pressure of 1.0MPa, it can deliver up to 318kgf of theoretical force.
No, the standard SAI cylinder does not hold position without live air pressure. For fail-safe load holding, you should use the SAIL variant with an air-released lock or an external rod lock.
