About the Airtac SAI63 Standard Cylinder SAI63AX5S
The AirTAC SAI63X5-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short stroke clamping and ejection tasks. Delivering a push force of 1559 N at 0.5 MPa, this 63 mm bore unit provides substantial thrust within a minimal footprint. The 5 mm stroke is a non-standard configuration, made-to-order for applications requiring high force without extended travel.
This specific configuration includes a magnet (-S) for direct integration with CMSE and DMSE proximity sensors, fitting neatly into the dual sensor grooves machined into the extruded aluminum barrel. It is equipped with an SUS420J2 (code A) stainless steel piston rod for enhanced corrosion resistance and features PT tapered port threads. Adjustable air cushions at both ends ensure smooth deceleration even at the stroke limits.

Where the Airtac SAI63 Standard Cylinder SAI63AX5S Is Used
High-Force Short Clamping
Secures heavy automotive castings during machining operations using 1559 N of clamping force without requiring lengthy cylinder extension.
Rapid Ejection
Ejects dense metal parts from press dies with a quick 5 mm stroke, leveraging the 30-800 mm/s speed range for high-cycle production.
Position Verification
Uses the integrated -S magnet with DMSE sensors to confirm end-of-stroke positioning in automated assembly tooling.
Is the Airtac SAI63 Standard Cylinder SAI63AX5S the Right Cylinder?
Select this 63 mm bore cylinder when a smaller 50 mm bore (providing 982 N push at 0.5 MPa) lacks sufficient force for your clamping requirement. Because the 5 mm stroke is exceptionally short, side-load stress on the rod bearing is minimal, but ensure your mounting geometry is perfectly aligned to avoid binding. The standard SAI63X5-S does not hold its load when air pressure is removed; for dead-end clamping without continuous live pressure, specify the SAIL variant with an air-released lock or the BSAI clamp-lock cylinder.
As a true ISO 15552 profile cylinder, it offers a dimensionally interchangeable mounting interface for seamless drop-in replacement alongside other ISO 15552 cylinders. To match this exact unit, specify a 63 mm bore, 5 mm stroke, G3/8 PT port, and the -S magnet option. Compatible mounting accessories include LB foot brackets, FA flanges, and TC trunnion styles.
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 SAI63AX5S FAQ
At an operating pressure of 0.5 MPa, this 63 mm bore cylinder generates a push force of 1559 N and a pull force of 1402 N. At 0.7 MPa, the push force increases to 2182 N.
Yes. The SAI series is built to the ISO 15552 standard, meaning its mounting dimensions are fully interchangeable with other ISO 15552 profile cylinders. Ensure your setup matches the 63 mm bore, G3/8 port, and desired stroke.
