About the Airtac SAI63 Standard Cylinder SAI63BX115S
The AirTAC SAI63X115-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 115 mm stroke provides an optimal mid-range extension for automated assembly and material handling tasks. Built with an extruded aluminum barrel, this tie-rod-less design ensures dimensionally interchangeable mounting per ISO 15552.
This specific configuration includes a SUS304 stainless steel piston rod (material code B) for superior corrosion resistance in humid or washdown environments. It features PT tapered port threads and is equipped with a magnet (-S) to operate seamlessly with CMSE or DMSE sensor switches in the dual side grooves.

Where the Airtac SAI63 Standard Cylinder SAI63BX115S Is Used
Assembly Pressing
Provides the precise 1559 N force at 0.5 MPa needed for seating bearings and pins in automated machining cells.
Material Diversion
The 115 mm stroke actuates diverter gates smoothly on packaging lines, utilizing adjustable air cushions at both ends.
Clamping Fixtures
Holds workpieces securely during welding or machining, leveraging the SUS304 rod for resilience against coolant splashes.
Is the Airtac SAI63 Standard Cylinder SAI63BX115S the Right Cylinder?
Select this 63 mm bore when an application requires roughly 1559 N of thrust at 0.5 MPa, bridging the gap between the 50 mm bore (982 N) and the 80 mm bore (2513 N). For operations needing position holding without continuous air pressure, a standard SAI will drift; integrate the SAIL (air-released lock) or BSAI (clamp-lock) variant instead.
When specifying a direct replacement, match the 63 mm bore, 115 mm stroke, G3/8 PT ports, and mounting accessories like the FA flange or TC trunnion. Always include the -S magnet if CMSE/DMSE electronic position feedback is required.
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 SAI63BX115S FAQ
At 0.5 MPa operating pressure, this 63 mm bore cylinder generates 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X115-S is dimensionally interchangeable per ISO 15552. You can use it as a direct replacement for other ISO 15552 profile cylinders by matching the 63 mm bore, 115 mm stroke, and G3/8 port size.
