About the Airtac SAI63 Standard Cylinder SAI63AX115
The AirTAC SAI63X115 is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. With a 63 mm bore and 115 mm stroke, it provides the exact travel needed for mid-range automation tasks without excessive overhang.
This specific configuration features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if you add a magnet later.

Where the Airtac SAI63 Standard Cylinder SAI63AX115 Is Used
Parts Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for securing mid-sized metal components during machining operations.
Package Diverting
The 115 mm stroke offers precise actuation distance for routing packages on automated sorting conveyor lines.
Material Ejection
Generates sufficient push force to eject molded or stamped parts from automated production machinery.
Is the Airtac SAI63 Standard Cylinder SAI63AX115 the Right Cylinder?
If your application requires less thrust, stepping down to the 50 mm bore yields 982 N at 0.5 MPa, while moving up to the 80 mm bore provides 2513 N. Because this is a standard 115 mm stroke, side-load risks remain minimal, but always ensure the load is axially aligned to prevent premature rod-bearing wear.
Remember that the standard SAI does not hold loads when air pressure is removed; the piston will drift. For vertical or suspended loads that require fail-safe holding, specify the SAIL variant with an air-released lock or use an external pilot-operated check valve. This model is dimensionally interchangeable per ISO 15552, making it a drop-in replacement for other standard profile 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.
