About the Airtac SAI63 Standard Cylinder SAI63AX105
The AirTAC SAI63X105 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 105 mm stroke provides the exact mid-range extension needed for compact clamping and lifting tasks without excessive overhang.
Built with a SUS420J2 stainless steel piston rod, this unit offers superior corrosion resistance compared to standard carbon steel. It features PT tapered port threads and an extruded aluminum barrel with dual sensor grooves, allowing for flexible CMSE or DMSE switch mounting.

Where the Airtac SAI63 Standard Cylinder SAI63AX105 Is Used
Mid-Force Clamping
Secures heavy metal workpieces during machining operations where a shorter 100 mm stroke is insufficient to clear the fixture.
Component Lifting
Raises sub-assemblies on a production line using 1559 N of push force, taking advantage of the durable SUS420J2 rod.
Diversion Pushing
Actuates diverter arms to route medium-weight packaged goods, utilizing the precise 105 mm travel distance.
Is the Airtac SAI63 Standard Cylinder SAI63AX105 the Right Cylinder?
Select this 63 mm bore when a 50 mm cylinder (982 N at 0.5 MPa) lacks the power to move your load, but an 80 mm bore (2513 N) would be overkill. The 105 mm stroke is a custom intermediate length, ideal for applications requiring precise travel limits.
Because the standard SAI is double-acting, it relies entirely on continuous air pressure to maintain its position. If your system loses air or the valve centers, the piston will drift. For loads that must be held securely without live pressure, consider the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder. This model uses a G3/8 port and accepts standard ISO 15552 mounting accessories like FA flanges or TC trunnions.
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 SAI63AX105 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes. The SAI63X105 is a true ISO 15552 profile cylinder, making it dimensionally interchangeable with other ISO 15552 cylinders of the same bore and stroke. It uses a G3/8 port and standard mounting interfaces.
