About the Airtac SAI63 Standard Cylinder SAI63AX600S
The AirTAC SAI63X600-S is a double-acting profile cylinder built to strict ISO 15552 dimensional standards, ensuring direct drop-in interchangeability for equivalent ISO pneumatic actuators. Operating on filtered air, it delivers a robust 1559 N push force and 1402 N pull force at 0.5 MPa, making it well-suited for long-traverse material handling and heavy positioning tasks across its 600 mm stroke.
This specific configuration features a SUS420J2 stainless steel piston rod (option A) for superior corrosion resistance in humid or mildly chemically washed environments. The -S suffix denotes an integrated magnet for use with CMSE and DMSE sensor switches, which ride neatly in the dual-side extruded aluminum barrel grooves to streamline position feedback wiring.

Where the Airtac SAI63 Standard Cylinder SAI63AX600S Is Used
Long-Travel Material Pushing
Ideal for indexing products down an assembly line where the full 600 mm stroke clears wide machinery footprints without repositioning the entire actuator assembly.
Multi-Stage Machining Clamps
Provides the 1559 N clamping force needed to hold aluminum or mild steel castings firmly in place during light milling and drilling operations.
Automated Pallet Diversion
Drives heavy diverter arms on packaging conveyors, utilizing the dual-side sensor grooves to confirm stroke endpoints before triggering downstream sorting logic.
Is the Airtac SAI63 Standard Cylinder SAI63AX600S the Right Cylinder?
Choosing this 63 mm bore over the smaller 50 mm bore gives you a significant thrust upgrade, stepping up from 982 N to 1559 N at 0.5 MPa, while avoiding the bulkier 80 mm bore which outputs 2513 N. Because this model features a 600 mm stroke, the extended rod is highly susceptible to bending under side loads; always pair it with an external linear guide rail or use a guided cylinder to prevent premature rod-bearing wear.
For applications requiring the piston to hold a load securely during a complete loss of air pressure or valve centering, note that the standard adjustable air cushions only decelerate the piston near stroke ends and do not function as a brake. In those safety-critical scenarios, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant. To match this unit exactly, select a 63 mm bore, 600 mm stroke, G3/8 PT tapered port, and an -S magnet for sensor readiness.
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 SAI63AX600S FAQ
At a standard 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. If you increase the pressure to 0.7 MPa, the push force rises to 2182 N.
Yes. The SAI series is a genuine ISO 15552 profile cylinder, meaning its mounting interface and envelope dimensions are fully interchangeable with other ISO 15552 cylinders from various manufacturers. Always verify your specific mounting bracket and port requirements before swapping.
