About the Airtac SAI63 Standard Cylinder SAI63AX95
The AirTAC SAI63X95 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 95 mm stroke provides a compact extension distance ideal for mid-range automation tasks. The extruded aluminum barrel design omits tie-rods, offering a clean exterior that simplifies mounting and sensor placement.
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, and the barrel lacks the integrated magnet option, meaning it is optimized for purely mechanical actuation without direct position sensing.

Where the Airtac SAI63 Standard Cylinder SAI63AX95 Is Used
Mid-Force Clamping
Secures heavy metal workpieces during CNC machining using its 1559 N push force at 0.5 MPa without shifting the part.
Package Diverting
Actuates routing gates on high-speed packaging lines where a 95 mm stroke quickly redirects medium-weight cartons.
Press Ejection
Ejects formed parts from hydraulic presses, utilizing the SUS420J2 rod to withstand occasional moisture and shop coolant.
Is the Airtac SAI63 Standard Cylinder SAI63AX95 the Right Cylinder?
Select this 63 mm bore when an application requires approximately 1559 N of thrust at 0.5 MPa, bridging the gap between the 50 mm bore (982 N) and the 80 mm bore (2513 N). Because the stroke is under 300 mm, side-load stress on the rod bearing is minimal, though external guides should still be used for heavy off-center loads.
If the machinery requires the piston to maintain its position after a loss of air pressure, the standard SAI will drift and cannot hold the load. In such scenarios, specify the SAIL variant with an air-released lock or utilize an external pilot-operated check valve. For direct replacements, match the 63 mm bore, 95 mm stroke, G3/8 PT ports, and appropriate 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 SAI63AX95 FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder provides 1559 N of push force and 1402 N of pull force. If pressure is increased to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X95 is dimensionally interchangeable per ISO 15552. You can replace competing ISO 15552 profile cylinders by matching the 63 mm bore, 95 mm stroke, G3/8 port size, and mounting interface.
