About the Airtac SAI63 Standard Cylinder SAI63AX100
The AirTAC SAI63X100 is a double-acting ISO 15552 profile cylinder offering a push force of 1559 N at 0.5 MPa. Its 100 mm stroke makes it highly suitable for mid-range automation tasks requiring robust, consistent linear motion.
This specific configuration features a SUS420J2 stainless steel piston rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes dual-side sensor grooves, allowing for easy installation of CMSE or DMSE switches when position feedback is required.

Where the Airtac SAI63 Standard Cylinder SAI63AX100 Is Used
Clamping Fixtures
Provides the 1559 N force necessary to securely hold medium-sized metal or composite workpieces during machining operations.
Package Diverting
The 100 mm stroke offers rapid and precise movement for pushing packages off a high-speed conveyor belt line.
Material Bending
Generates consistent thrust for light-duty press and bending applications within automated fabrication cells.
Is the Airtac SAI63 Standard Cylinder SAI63AX100 the Right Cylinder?
If your application requires slightly less force, the SAI50X100 provides 982 N of push force at 0.5 MPa. For heavier loads, stepping up to the SAI80X100 yields 2513 N. Because this is a standard double-acting actuator, it cannot hold a load if air pressure drops; the SAIL variant with an air-released lock is recommended for fail-safe holding.
As a true ISO 15552 profile cylinder, it serves as a drop-in replacement for any standard 63 mm bore, 100 mm stroke cylinder with a G3/8 port. Ensure you select the appropriate mounting accessory, such as an FA flange or TC trunnion, and add the -S magnet option if you need electronic sensing.
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 SAI63AX100 FAQ
