About the Airtac SAI63 Standard Cylinder SAI63BX200
The AirTAC SAI63X200 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 200 mm stroke is well-suited for mid-range linear actuation tasks requiring consistent thrust and reliable kinetic energy absorption. The extruded aluminum barrel design omits tie-rods, providing a smooth exterior that integrates easily into tight machinery layouts.
This specific configuration features a SUS304 stainless steel rod for superior corrosion resistance in humid or washdown environments. It utilizes PT tapered port threads and does not include a magnet, meaning it is optimized for pure pneumatic actuation without internal position sensing.

Where the Airtac SAI63 Standard Cylinder SAI63BX200 Is Used
Automated Clamping
Provides 2182 N of push force at 0.7 MPa, making it ideal for securing heavy metal components during CNC machining or welding operations.
Product Diverters
The 200 mm stroke offers the precise extension needed to actuate sorting gates and diverter arms on high-speed packaging conveyors.
Material Lifts
Its robust 63 mm bore and SUS304 rod handle the vertical actuation of platform lifts in environments where moisture or minor splashing is present.
Is the Airtac SAI63 Standard Cylinder SAI63BX200 the Right Cylinder?
Selecting this 63 mm bore provides a substantial step up in thrust compared to the 50 mm bore variant, which offers 982 N at 0.5 MPa. If your application requires less force, stepping down saves air consumption; if you need significantly more power, the 80 mm bore yields 2513 N at 0.5 MPa. Because the 200 mm stroke is under the 300 mm threshold, standard rod-bearing bending is minimal, though external guides are still recommended for heavy offset loads.
As a true ISO 15552 cylinder, this model is dimensionally interchangeable with other ISO 15552 cylinders of the same bore, matching the G3/8 port, M16x1.5 rod thread, and 36 mm cushion length. Remember that the standard adjustable air cushions only decelerate the piston near stroke end; they do not hold a load. If your machine loses air pressure, the rod will drift, requiring an external check valve or the SAIL locking variant for position holding.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAI63 Standard Cylinder SAI63BX200 FAQ
The SAI63X200 generates 1559 N of push force and 1402 N of pull force at 0.5 MPa. At the standard 0.7 MPa operating pressure, it delivers 2182 N of push force.
Yes. The SAI63X200 is a genuine ISO 15552 profile cylinder, meaning its mounting interface and physical envelope are dimensionally interchangeable with other ISO 15552 cylinders of the same bore size, allowing for a direct replacement.
