About the Airtac SAI63 Standard Cylinder SAI63AX80
The AirTAC SAI63X80 is a double-acting ISO 15552 profile cylinder offering 1559 N of push force at 0.5 MPa. Its 80 mm stroke is well-suited for compact, high-force clamping and indexing tasks. The extruded aluminum barrel design omits tie rods, providing a clean exterior that resists mechanical interference.
This specific configuration features a SUS420J2 stainless steel piston rod for superior corrosion resistance in humid or mildly chemically exposed environments. It uses PT tapered port threads and lacks a standard magnet, but the barrel includes dual sensor grooves for adding CMSE or DMSE switches if future automation needs arise.

Where the Airtac SAI63 Standard Cylinder SAI63AX80 Is Used
Heavy-Duty Clamping
Provides 1559 N of push force at 0.5 MPa to securely hold heavy metal workpieces during milling or drilling operations.
Package Diverting
Executes rapid 80 mm strokes to push heavy cartons or pallets between adjacent conveyor lines at speeds up to 800 mm/s.
Press Fit Assembly
Delivers consistent downward force to seat bearings or pins into housings without requiring a full hydraulic press.
Is the Airtac SAI63 Standard Cylinder SAI63AX80 the Right Cylinder?
Select this 63 mm bore when a 50 mm bore (982 N at 0.5 MPa) is insufficient for your load, but you want to avoid the larger 80 mm bore's 2513 N bulk and higher air consumption. The 80 mm stroke keeps the unsupported rod length short, minimizing rod-bearing bending under typical side loads.
As a standard double-acting actuator, this cylinder will drift if air pressure is lost or the control valve is centered; it cannot hold a load mechanically. If your application requires static holding without continuous live pressure, consider the SAIL (air-released lock) or BSAI (clamp-lock) variants. This unit serves as a direct dimensional drop-in replacement for any ISO 15552 cylinder with a 63 mm bore, 80 mm stroke, G3/8 port, and standard 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 SAI63AX80 FAQ
At 0.5 MPa, the SAI63X80 provides 1559 N of push force and 1402 N of pull force. If operated at 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X80 is dimensionally interchangeable per ISO 15552 standards. You can drop it in as a replacement for other ISO 15552 profile cylinders with a 63 mm bore, 80 mm stroke, and G3/8 port.
