About the Airtac SAI63 Standard Cylinder SAI63AX165
The AirTAC SAI63X165 is a double-acting ISO 15552 profile cylinder built to deliver 1559 N of push force at 0.5 MPa. Its 165 mm stroke provides the exact mid-range extension needed for robust material handling and automated clamping tasks. The extruded aluminum barrel eliminates tie-rods, creating a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Fluid ports utilize a PT tapered thread type, ensuring tight pneumatic connections. Because a magnet is not specified, this unit operates without internal magnetic sensing rings.

Where the Airtac SAI63 Standard Cylinder SAI63AX165 Is Used
Automated Clamping Stations
Provides the 1559 N push force required to secure heavy metal workpieces during CNC machining or welding operations.
Package Diverters
Uses the 165 mm stroke to push parcels smoothly off a main conveyor belt onto secondary sorting lanes.
Press and Riveting Jigs
Applies consistent downward pressure for assembling small components, benefiting from the adjustable end cushions.
Is the Airtac SAI63 Standard Cylinder SAI63AX165 the Right Cylinder?
Select this 63 mm bore when a 50 mm bore falls short—yielding 1402 N pull force at 0.5 MPa compared to the smaller bore's 825 N. If your application requires even greater thrust, stepping up to an 80 mm bore provides 2268 N of pull force at the same pressure. The 165 mm stroke is well below the 300 mm threshold, so rod-bearing bending from side loads is minimal, though external guides are always recommended for heavy off-center loads.
This model features adjustable air cushions at both ends to decelerate the piston smoothly, but it is not a locking cylinder. If your machinery requires the load to be held securely in place during a loss of air pressure, you must integrate an external pilot-operated check valve or specify the SAIL variant with an air-released 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 SAI63AX165 FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X165 is dimensionally interchangeable per ISO 15552. You can drop it into existing ISO 15552 mounting accessories, matching the 63 mm bore, 165 mm stroke, and G3/8 port interface.
