About the Airtac SAI63 Standard Cylinder SAI63BX105S
The AirTAC SAI63X105-S is a double-acting ISO 15552 profile cylinder offering 1559 N of push force at 0.5 MPa. Its 105 mm stroke falls outside the standard 25 mm increments, making it a made-to-order option for precise mid-range actuation. The extruded aluminum barrel eliminates tie-rods, providing a clean exterior that drops directly into ISO 15552 mounting interfaces.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance in humid or chemically exposed settings. It also features a built-in magnet (-S) enabling seamless position detection with CMSE or DMSE switches installed into the dual sensor grooves on the barrel.

Where the Airtac SAI63 Standard Cylinder SAI63BX105S Is Used
Custom Jig Positioning
The 105 mm stroke provides exact reach for custom machining jigs where a 100 mm stroke falls short, ensuring parts clear the tooling path reliably.
Pallet Denester
Equipped with a SUS304 rod and CMSE sensors, this cylinder excels in packaging machinery that requires precise vacuum cup placement to separate empty pallets.
Mid-Range Clamping
Delivering 1559 N of push force at 0.5 MPa, it provides secure holding force for medium-duty assembly station clamps without requiring high supply pressure.
Is the Airtac SAI63 Standard Cylinder SAI63BX105S the Right Cylinder?
When sizing this actuator, stepping down to the 50 mm bore drops the 0.5 MPa push force to 982 N, while stepping up to the 80 mm bore raises it to 2513 N. Because the 105 mm stroke is non-standard, expect a slightly longer lead time compared to common 100 mm increments. The adjustable air cushions at both ends decelerate the piston to prevent end-cap impact, but this standard SAI will not hold a load if air pressure drops; for fail-safe holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. To match this cylinder, use a 63 mm bore, 105 mm stroke, PT G3/8 port, and standard ISO 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.
Airtac SAI63 Standard Cylinder SAI63BX105S FAQ
At 0.5 MPa, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At the maximum 1.0 MPa operating pressure, it can deliver up to 318 kgf of theoretical force.
Yes, the SAI63X105-S is dimensionally interchangeable per ISO 15552. You can drop it into existing mounts designed for other ISO 15552 profile cylinders, provided the 105 mm stroke and G3/8 PT ports match your setup.
