About the Airtac SAI63 Standard Cylinder SAI63AX900S
The AirTAC SAI63X900-S is a double-acting ISO 15552 profile cylinder engineered for long-trroke automation tasks. It provides a robust push force of 1559 N and a pull force of 1402 N at 0.5 MPa, operating efficiently at speeds between 30 and 800 mm/s. This 900 mm stroke length is optimal for transferring components across wide machine footprints.
Built to exacting standards, this genuine AirTAC unit features a SUS420J2 stainless steel piston rod (material code A) for superior corrosion resistance in humid environments. The integrated magnet (-S) enables seamless position detection using CMSE or DMSE switches seated in the dual sensor grooves along the extruded aluminum barrel. Fluid compatibility is limited to filtered 40 um air.

Where the Airtac SAI63 Standard Cylinder SAI63AX900S Is Used
Long-Stroke Transfer
Pushes workpieces between distant machining stations using the full 900 mm stroke extension.
High-Bay Ejection
Ejects packaged goods from elevated storage tiers where a 1559 N push force is required.
Large Press Handling
Feeds heavy sheet metal blanks into forming presses, utilizing the SUS420J2 rod for durability.
Is the Airtac SAI63 Standard Cylinder SAI63AX900S the Right Cylinder?
Selecting this 63 mm bore cylinder makes sense when your application requires the 1559 N push force at 0.5 MPa, stepping up from a 50 mm bore that offers 982 N. Because this model features a 900 mm stroke, the extended rod is highly susceptible to bending under side loads. To prevent premature rod-bearing wear, implement an external linear guide or choose a guided cylinder module to absorb lateral forces.
This model uses PT tapered G3/8 ports and an M16x1.5 rod thread. As a true ISO 15552 profile cylinder, it serves as a direct dimensional replacement for other standard ISO 15552 actuators. Note that the adjustable air cushions only decelerate the piston at stroke ends; if the air supply is lost, the rod will drift. For dead-load holding, specify the SAIL variant or an external pilot-operated check valve.
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 SAI63AX900S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. If pressure increases to 0.7 MPa, the push force rises to 2182 N.
Yes, the SAI63X900-S is dimensionally interchangeable with any standard ISO 15552 profile cylinder. You can swap it directly using the existing mounting accessories and G3/8 port connections.
