About the Airtac SAI63 Standard Cylinder SAI63AX210S
The AirTAC SAI63X210-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa. Its 210 mm stroke provides extended travel for mid-range automation tasks, while the extruded aluminum barrel omits tie rods for a clean, standardized mounting interface.
This specific configuration includes a SUS420J2 stainless steel piston rod for superior corrosion resistance and a built-in magnet (-S) for use with CMSE and DMSE reed switches. The dual sensor grooves on the barrel allow flexible switch placement, and the adjustable air cushions at both ends ensure smooth deceleration.

Where the Airtac SAI63 Standard Cylinder SAI63AX210S Is Used
Extended-Reach Clamping
Ideal for securely holding workpieces at a distance, using the 210 mm stroke to clear robotic arms or secondary tooling before applying 1559 N of clamping force.
Package Diversion
Provides the reach and speed needed to push heavy cartons from a main conveyor line to a secondary packaging lane, benefiting from the dual air cushions for impact absorption.
Lift and Transfer
Suitable for lifting medium-weight pallets or fixtures between processing stations, utilizing the integrated magnet for precise end-of-stroke confirmation.
Is the Airtac SAI63 Standard Cylinder SAI63AX210S the Right Cylinder?
Because this 210 mm stroke exceeds the standard increment table, it is produced as a non-standard made-to-order unit; expect a slightly longer lead time. If your application requires less force, stepping down to a 50 mm bore yields 982 N at 0.5 MPa, whereas moving up to an 80 mm bore provides 2513 N.
With a 210 mm stroke, the unsupported rod length is moderate, so ensure your load is guided to prevent side-load bending on the rod bearing. Note that a standard SAI cylinder relies on live air pressure to hold a load; if pneumatic pressure drops, the piston will drift. For fail-safe position holding, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. This model is dimensionally interchangeable per ISO 15552 and features PT tapered ports.
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 SAI63AX210S FAQ
