About the Airtac SAI63 Standard Cylinder SAI63BX115
The AirTAC SAI63X115 is a double-acting ISO 15552 profile cylinder offering a 1559 N push force at 0.5 MPa. Its 115 mm stroke provides a reliable mid-range extension for standard automation tasks.
This specific configuration features a SUS304 stainless steel piston rod (option B), making it highly suitable for environments where corrosion resistance is critical. It uses PT tapered port threads and lacks a standard magnet, meaning it is optimized for pure pneumatic actuation without external sensor switching.

Where the Airtac SAI63 Standard Cylinder SAI63BX115 Is Used
Stainless Rod Actuation
Ideal for packaging machinery requiring high corrosion resistance, utilizing the SUS304 rod for washdown or humid settings.
Mid-Stroke Diverter
Perfectly suited for diverting packages on a conveyor line where a 115 mm stroke provides precise product routing.
Clamping Fixture
Provides reliable clamping force for holding workpieces during secondary machining or assembly operations.
Is the Airtac SAI63 Standard Cylinder SAI63BX115 the Right Cylinder?
Choose this 63 mm bore when a 50 mm bore (982 N at 0.5 MPa) is insufficient and an 80 mm bore (2513 N at 0.5 MPa) would be physically oversized. The 115 mm stroke falls below the 300 mm side-load threshold, so standard mounting accessories like FA flanges or LB foot brackets are fully sufficient.
Because this is a double-acting cylinder, it will not hold a load if air pressure drops. If your application requires dead-stop holding without live pressure, consider the SAIL (air-released lock) variant or an external rod lock. As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders.
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.
