About the Airtac SAI63 Standard Cylinder SAI63AX175
The AirTAC SAI63X175 is a double-acting ISO 15552 profile cylinder offering a 1559 N push force at 0.5 MPa. With a 175 mm stroke, it is perfectly sized for mid-range automation tasks requiring substantial movement and reliable energy transfer.
This specific configuration features a SUS420J2 stainless steel rod for superior corrosion resistance. It utilizes PT tapered port threads and, because it lacks the -S magnet suffix, is optimized for purely mechanical actuation rather than direct sensor mounting.

Where the Airtac SAI63 Standard Cylinder SAI63AX175 Is Used
Clamping Mechanisms
Provides the 1559 N force needed to secure heavy metal workpieces during machining operations.
Material Diverting
Uses the 175 mm stroke to push packages smoothly across conveyor lanes at high speeds.
Press Operations
Drives small pneumatic presses for assembly tasks requiring consistent mid-level force.
Is the Airtac SAI63 Standard Cylinder SAI63AX175 the Right Cylinder?
Selecting this 63 mm bore provides a significant thrust upgrade over the 50 mm version, which yields 982 N at 0.5 MPa. If your application requires less force, stepping down saves space and air consumption.
As a true ISO 15552 profile cylinder, this model serves as a direct dimensional drop-in replacement for other ISO 15552 units of the same bore and stroke. It features a G3/8 port, accepts standard mounting accessories like FA flanges or TC trunnions, and requires an external pilot-operated check valve or the SAIL lock variant if you need to hold a load safely during air loss.
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 SAI63AX175 FAQ
