About the Airtac SAI63 Standard Cylinder SAI63AX100S
The AirTAC SAI63X100-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 100 mm stroke provides a compact yet powerful extension for mid-range automation tasks. The extruded aluminum barrel design eliminates tie-rods, ensuring a clean exterior that drops directly into standard ISO 15552 mounting footprints.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. Equipped with a magnetic piston (-S), it seamlessly integrates with CMSE and DMSE sensor switches fitted into the dual side grooves of the barrel. It also features adjustable air cushions at both ends to decelerate the payload smoothly.

Where the Airtac SAI63 Standard Cylinder SAI63AX100S Is Used
Mid-Range Clamping
Provides reliable 1559 N clamping force at 0.5 MPa for securing medium-sized metal workpieces during machining operations.
Package Diverting
Actuates diverter arms on packaging lines where a 100 mm stroke quickly pushes cartons to adjacent lanes without lag.
Press Ejection
Ejects formed parts from light pneumatic presses, utilizing the adjustable air cushions to prevent end-of-stroke impact damage.
Is the Airtac SAI63 Standard Cylinder SAI63AX100S the Right Cylinder?
Selecting this 63 mm bore is ideal when a 50 mm bore (982 N at 0.5 MPa) lacks the necessary thrust, but an 80 mm bore (2513 N at 0.5 MPa) would be physically oversized and consume excess air. The 100 mm stroke keeps the rod bearing load minimal, meaning side-load stress is naturally low.
For drop-in replacements, match the 63 mm bore, 100 mm stroke, G3/8 PT port thread, and your required mounting accessory (such as LB foot or TC trunnion). Because it is a standard double-acting cylinder, it will not hold a load if air pressure drops; use the SAIL variant with an air-released lock if your application requires fail-safe position holding.
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 SAI63AX100S FAQ
At a 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 SAI63X100-S is dimensionally interchangeable per ISO 15552. You can drop it into existing setups by matching the 63 mm bore, 100 mm stroke, G3/8 port, and mounting accessories, provided you account for the PT tapered port threads.
