About the Airtac SAI63 Standard Cylinder SAI63X5S
The AirTAC SAI63X5-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short actuation. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore unit is built for high-impact duties in confined spaces. The integrated magnet enables precise position detection using CMSE or DMSE switches.
Equipped with a standard carbon steel piston rod and PT tapered port threads, it ensures robust, leak-free pneumatic connections. The extruded aluminum barrel features dual sensor grooves, simplifying switch installation on either side without requiring extra brackets.

Where the Airtac SAI63 Standard Cylinder SAI63X5S Is Used
Short-Stroke Stamping
Ideal for applying quick 1559 N stamping or marking forces in compact automated machinery.
Parts Ejection
Provides a rapid 5 mm kick to eject finished components from machining centers.
Clamping Operations
Secures workpieces firmly in fixtures using high pull force without occupying vertical space.
Is the Airtac SAI63 Standard Cylinder SAI63X5S the Right Cylinder?
Choose this 5 mm stroke model when a brief, powerful tapping or clamping motion is required without extending the footprint. If your assembly needs less impact, stepping down to a 50 mm bore yields 982 N at 0.5 MPa. Conversely, upgrading to an 80 mm bore provides 2513 N for heavier loads.
Because the stroke is minimal, rod-bearing bending is negligible, making external guides unnecessary here. For operations that must maintain position without continuous air pressure, pair this cylinder with the SAIL locking variant or an external pilot check valve. This profile cylinder is fully interchangeable with standard ISO 15552 mounting dimensions.

- ✓ 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.
