About the Airtac SAI63 Standard Cylinder SAI63AX210
The AirTAC SAI63X210 is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 210mm stroke. It generates a push force of 1559N at 0.5MPa and 2182N at 0.7MPa, making it well-suited for mid-range industrial actuation. This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel.
Because the 210mm stroke falls outside the standard incremental grid, it is manufactured as a non-standard stroke, though it remains well within the 1500mm maximum limit for this bore size. The extruded aluminum barrel includes sensor grooves on both sides, allowing for direct mounting of CMSE or DMSE switches if a magnet is specified in future iterations. The PT tapered port threads ensure a robust, leak-free pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63AX210 Is Used
Automated Clamping
Provides reliable holding power for mid-sized machining fixtures requiring 2182N of push force at 0.7MPa.
Material Diversion
Actuates diverters and gates on processing lines where a 210mm stroke is optimal for routing packages.
Assembly Pressing
Drives small press fits and component seating operations in automated assembly machinery.
Is the Airtac SAI63 Standard Cylinder SAI63AX210 the Right Cylinder?
When selecting this model, verify that 1559N at 0.5MPa provides adequate thrust; stepping up to an 80mm bore yields 2513N if higher capacity is required. Since the 210mm stroke is below the 300mm threshold, rod-bearing bending is less critical, but side loads should still be minimized or managed with an external guide. This cylinder is dimensionally interchangeable per ISO 15552, serving as a drop-in replacement for other ISO 15552 profile cylinders. Note that a plain SAI does not hold its load when air pressure is removed; for position holding, consider the SAIL variant with an air-released lock.
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 SAI63AX210 FAQ
At 0.7MPa operating pressure, the SAI63X210 generates a push force of 2182N and a pull force of 1402N.
No, the standard SAI cylinder will drift if air pressure is lost. For load-holding applications, use the SAIL variant with an air-released lock or an external rod lock.
