About the Airtac SAI63 Standard Cylinder SAI63X225S
The AirTAC SAI63X225-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 225mm stroke. It delivers a thrust of 1559 N at 0.5 MPa, making it highly suitable for medium-duty automation tasks. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior while maintaining strict dimensional interchangeability with other ISO 15552 cylinders.
Configured with a standard carbon steel piston rod and a built-in magnet (-S), this model is fully compatible with CMSE and DMSE reed switches. The dual sensor grooves machined into both sides of the barrel allow for highly flexible mounting of position sensors, ensuring seamless integration into existing control architectures.

Where the Airtac SAI63 Standard Cylinder SAI63X225S Is Used
Package Diversion
Ideal for pushing packages on sorting lines, utilizing the 1559 N force at 0.5 MPa to reliably redirect heavy boxes without hesitation.
Clamping Fixtures
Provides consistent clamping pressure for machining or welding jigs, holding workpieces firmly in place during automated processes.
Material Ejection
Excels in ejecting molded or stamped parts from machinery, where the 225mm stroke ensures components clear the work area entirely.
Is the Airtac SAI63 Standard Cylinder SAI63X225S the Right Cylinder?
If your application requires slightly less force, stepping down to the 50mm bore yields 982 N at 0.5 MPa, while the 80mm bore offers 2513 N for heavier demands. Because this 225mm stroke exceeds 300mm? No, but it is approaching a length where side loads can begin to affect the rod bearing. For any stroke of 300mm or more, utilizing external guides or a dedicated guided cylinder is strongly recommended to prevent rod bending and premature seal wear.
This cylinder uses a G3/8 PT tapered port and an M16x1.5 rod thread. It functions as a direct replacement for any standard ISO 15552 footprint, utilizing common mounting accessories like FA flanges or TC trunnions. Note that standard air cushions only decelerate the piston at end-of-stroke; they do not hold loads. If position holding without air pressure is required, consider the SAIL locking variant or an external rod lock.
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 SAI63X225S FAQ
At an operating pressure of 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 SAI63X225-S is dimensionally interchangeable per ISO 15552 standards. You can use the same mounting accessories and port spacing (G3/8) for a direct replacement.
