About the Airtac SAI63 Standard Cylinder SAI63AX230S
The AirTAC SAI63X230-S is a double-acting ISO 15552 profile cylinder engineered to deliver a push force of 1559 N and a pull force of 1402 N at 0.5 MPa. The 230 mm stroke provides ample extension for mid-range actuation tasks, operating efficiently within a speed range of 30-800 mm/s. As a genuine AirTAC component, it ensures reliable performance across diverse pneumatic setups.
This specific configuration features a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in mildly aggressive environments. Equipped with a standard -S magnet, it seamlessly integrates CMSE and DMSE series sensor switches via the dual-side extruded aluminum barrel grooves for precise end-of-stroke detection. The unit utilizes PT tapered port threading (G3/8) and incorporates adjustable air cushions at both ends to smoothly decelerate the payload.

Where the Airtac SAI63 Standard Cylinder SAI63AX230S Is Used
Automated Clamping
Provides 1559 N of push force at 0.5 MPa to securely hold medium-sized metal workpieces during machining or welding operations.
Material Diverting
The 230 mm stroke actuates diverter arms on production lines, moving packaged goods between adjacent conveyor belts with reliable speed.
Press Ejection
Utilizes its 1402 N pull force to retract finished parts from small pneumatic presses, taking advantage of the -S magnet for timed ejection signals.
Is the Airtac SAI63 Standard Cylinder SAI63AX230S the Right Cylinder?
If your application requires less force, stepping down to the 50 mm bore yields 982 N of push force at 0.5 MPa, while moving up to the 80 mm bore provides 2513 N. The 230 mm stroke falls below the 300 mm side-load threshold, but for any offset loads, utilizing an external guide rod is recommended to prevent premature wear on the rod bearing. Because this is a double-acting cylinder, it relies on continuous air pressure to hold its position; if the air is exhausted, the piston will drift. For applications requiring dead-stop holding without live pressure, consider the SAIL (air-released lock) variant or an external rod lock. This model serves as a drop-in replacement for any ISO 15552 cylinder with matching 63 mm bore, 230 mm stroke, G3/8 PT ports, 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.
