About the Airtac SAI63 Standard Cylinder SAI63AX240
The AirTAC SAI63X240 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 240mm stroke. It generates 1559N of push force at 0.5MPa, making it a robust choice for medium-duty automation. The extruded aluminum barrel omits tie-rods, providing a clean exterior that simplifies machine integration.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for superior corrosion resistance in humid environments. It uses PT tapered port threads. For applications requiring position holding without air pressure, consider the SAIL locking variant.

Where the Airtac SAI63 Standard Cylinder SAI63AX240 Is Used
Automated Assembly Presses
Provides 1559N of push force at 0.5MPa for driving pins and fastening components securely in automated assembly lines.
Material Diverters
Actuates sorting arms and diverter gates on conveyor systems, utilizing the 240mm stroke to redirect packages efficiently.
Packaging Equipment
Handles product positioning and flap folding in packaging machinery, benefiting from the adjustable air cushions at both stroke ends.
Is the Airtac SAI63 Standard Cylinder SAI63AX240 the Right Cylinder?
Stepping down to the 50mm bore drops the 0.5MPa push force to 982N, while the 80mm bore increases it to 2513N. The 240mm stroke is a standard length, but strokes of 300mm or more require careful management of side loads to prevent rod-bearing bending; external guides or a guided cylinder are recommended for long unsupported rods. Because this is a double-acting cylinder, it does not hold its load if air pressure is lost—use an external rod lock for safety. As a dimensionally interchangeable ISO 15552 unit, it serves as a direct drop-in replacement matching the 63mm bore, 240mm stroke, G3/8 port, and standard mounting accessories like FA flanges.
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.
