About the Airtac SAI63 Standard Cylinder SAI63AX10
The AirTAC SAI63X10 is a double-acting ISO 15552 profile cylinder engineered for tight-space actuation. It provides 1559 N of push force at 0.5 MPa, utilizing a 10 mm stroke for high-impact clamping or short ejector movements.
Built with an extruded aluminum barrel, this model omits tie-rods for a cleaner exterior. The piston rod uses SUS420J2 stainless steel for superior corrosion resistance, and the PT tapered port ensures a robust pneumatic seal. As a non-standard stroke configuration, it is manufactured to order for specialized short-travel machinery.

Where the Airtac SAI63 Standard Cylinder SAI63AX10 Is Used
Short-Stroke Clamping
Delivers 1559 N of force in a 10 mm stroke for securing heavy workpieces during machining operations.
Compact Ejection
Fits into tight machine clearances to eject finished parts quickly without requiring a long extension.
Press Assembly
Performs localized pressing and riveting tasks where a full standard stroke would be too slow.
Is the Airtac SAI63 Standard Cylinder SAI63AX10 the Right Cylinder?
For slightly lower force requirements, stepping down to the SAI50 bore yields 982 N at 0.5 MPa. If your application requires holding a load without live air pressure, note that the SAI's adjustable air cushions only decelerate the piston at stroke end and do not function as a lock; consider the SAIL variant for fail-safe holding. This 10 mm stroke configuration is a made-to-order non-standard size. It provides a drop-in ISO 15552 mounting interface with a G3/8 PT port, compatible with FA/FB flanges or TC trunnion brackets, and requires no -S magnet unless sensors are needed.
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 SAI63AX10 FAQ
At 0.5 MPa, the SAI63X10 generates 1559 N of push force and 1402 N of pull force. It can reach up to 2182 N at 0.7 MPa.
Yes, the SAI63X10 is dimensionally interchangeable per ISO 15552 standards, meaning it matches the mounting interface of other ISO 15552 profile cylinders.
