About the Airtac SAI63 Standard Cylinder SAI63BX15S
The AirTAC SAI63X15-S is a double-acting ISO 15552 profile cylinder engineered for short-stroke clamping and ejection tasks. It generates 1559 N of push force at 0.5 MPa, utilizing a compact 15 mm stroke that minimizes overall length while maintaining standardized mounting dimensions.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance in washdown or chemically active environments. The integrated magnet (-S) enables seamless position detection with CMSE or DMSE switches fitted into the dual sensor grooves on the extruded aluminum barrel.

Where the Airtac SAI63 Standard Cylinder SAI63BX15S Is Used
Part Ejection
Provides robust 1559 N push force to eject finished metal components from machining centers in tight cell layouts.
Clamping Fixtures
Ideal for holding workpieces securely during welding or drilling, utilizing its short 15 mm stroke for rapid cycle times.
Sensor-Driven Sorting
The internal magnet works with DMSE switches to confirm stroke completion, enabling precise diverting of parts on conveyors.
Is the Airtac SAI63 Standard Cylinder SAI63BX15S the Right Cylinder?
Select this 63 mm bore when an application requires more power than the 50 mm variant (982 N at 0.5 MPa) but lacks the space for a longer stroke. The 15 mm movement is optimal for gripping, pressing, or holding parts securely. Because the stroke is very short, side-load stress on the rod bearing is minimal compared to longer strokes.
As a true ISO 15552 profile cylinder, it serves as a direct dimensional direct replacement for other standardized ISO 15552 cylinders. Ensure your setup uses PT tapered port fittings for the G3/8 air supply. If the machinery loses air pressure, this standard cylinder cannot hold a load vertically; consider the SAIL locking variant for fail-safe vertical holding.
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.
