About the Airtac SAI63 Standard Cylinder SAI63AX225
The AirTAC SAI63X225 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 225mm stroke. It generates 1559N of push force at 0.5 MPa, making it well-suited for mid-weight industrial actuation tasks.
This variant is configured with a SUS420J2 stainless steel piston rod for superior corrosion resistance and features PT tapered G3/8 port threads. The extruded aluminum barrel includes dual sensor grooves, allowing for easy integration of CMSE or DMSE switches when position feedback is required.

Where the Airtac SAI63 Standard Cylinder SAI63AX225 Is Used
Automated Clamping
Provides reliable 1559N push force at 0.5 MPa for securing medium-weight metal components during machining operations.
Material Diverting
Drives diverter arms on packaging lines where a 225mm stroke is required to redirect products between conveyor belts.
Press Assembly
Actuates small pneumatic presses for bearing insertion or light-duty riveting tasks requiring consistent force output.
Is the Airtac SAI63 Standard Cylinder SAI63AX225 the Right Cylinder?
Selecting this 63mm bore provides a balanced 1559N output at 0.5 MPa; stepping down to a 50mm bore drops the force to 982N, while an 80mm bore increases it to 2513N. Because the 225mm stroke is under the 300mm threshold, standard rod bearing bending is minimal, but external guides should still be used to manage any slight side loads.
For applications requiring the load to be held in place during a complete loss of air pressure, note that the standard adjustable air cushions only decelerate the piston near stroke end and do not function as a brake. In those scenarios, consider the SAIL lock variant or an external rod lock. As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for other ISO 15552 cylinders matching the 63mm bore, 225mm stroke, G3/8 port, and standard mounting accessories.
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.
