About the Airtac SAI63 Standard Cylinder SAI63AX10S
The AirTAC SAI63X10-S is a double-acting ISO 15552 profile cylinder engineered for ultra-short stroke requirements. Delivering a push force of 1559 N at 0.5 MPa, this 63mm bore actuator integrates a 10mm stroke for high-force clamping and ejecting tasks. The extruded aluminum barrel design omits tie-rods, providing a clean exterior that is dimensionally interchangeable with other ISO 15552 cylinders.
This specific configuration includes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance in humid environments. The -S suffix indicates an integrated magnet for position sensing, allowing seamless mounting of CMSE or DMSE switches along the dual sensor grooves. Fluid ports feature PT tapered threads, and the unit supports adjustable air cushions at both ends to manage impact deceleration.

Where the Airtac SAI63 Standard Cylinder SAI63AX10S Is Used
High-Force Clamping
Ideal for securing heavy workpieces during machining operations where a short stroke and 1559 N of force are required.
Product Ejection
Delivers rapid, powerful ejection of finished parts from conveyor lines within extremely tight axial spaces.
Pressing Operations
Suitable for short-press applications in assembly lines, leveraging its robust 63mm profile and SUS420J2 rod.
Is the Airtac SAI63 Standard Cylinder SAI63AX10S the Right Cylinder?
Selecting the SAI63X10-S is optimal when an application demands substantial thrust within a severely confined footprint. If a smaller displacement is acceptable, the 50mm bore variant yields 982 N at 0.5 MPa; conversely, upgrading to an 80mm bore provides 2513 N for heavier loads. Because the 10mm stroke is a non-standard, made-to-order dimension, ensure your machinery can accommodate the specific extended and retracted lengths.
This actuator utilizes adjustable air cushions to reduce end-of-stroke impact, but it cannot hold a load if air pressure is lost. For vertical or suspended loads requiring fail-safe positioning, specify the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variant instead of the standard model. As a true ISO 15552 cylinder, it serves as a direct dimensional replacement for any compliant profile cylinder, utilizing a G3/8 port, M16x1.5 rod thread, and standard FA/FB flange or TC trunnion accessories.
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 SAI63AX10S FAQ
At 0.5 MPa, this 63mm 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 profile cylinder is dimensionally interchangeable per ISO 15552 standards. You can drop it into existing mounts using standard accessories, provided the 10mm non-standard stroke meets your application requirements.
