About the Airtac SAI63 Standard Cylinder SAI63AX30
The AirTAC SAI63X30 is a double-acting ISO 15552 profile cylinder with a compact 30mm stroke. It delivers 1559 N of push force at 0.5 MPa, making it well-suited for high-force clamping and short-travel positioning tasks.
This unit features a SUS420J2 stainless steel piston rod for superior corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides, allowing for easy switch mounting if position feedback is needed later.

Where the Airtac SAI63 Standard Cylinder SAI63AX30 Is Used
Heavy-Duty Clamping
Provides 1559 N of push force at 0.5 MPa for securing heavy metal workpieces during machining operations.
Product Ejection
Ideal for short-travel ejection of dense components from conveyor lines without taking up excessive machine footprint.
Press Assembly
Exerts reliable downward pressure for pressing small bearings or pins into housings on automated lines.
Is the Airtac SAI63 Standard Cylinder SAI63AX30 the Right Cylinder?
Choose this 63mm bore when 50mm cylinders (982 N at 0.5 MPa) lack the necessary thrust. The short 30mm stroke minimizes rod extension, significantly reducing side-load stress on the rod bearing. For applications requiring position holding without constant air pressure, select the SAIL locking variant instead of relying on the standard adjustable air cushions.
This model uses a PT tapered G3/8 port and is dimensionally interchangeable per ISO 15552. You can pair it with FA flanges or TC trunnion mounts depending on your load orientation.
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.
