About the Airtac SAI63 Standard Cylinder SAI63AX280S
The AirTAC SAI63X280-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and 280mm stroke. It supplies 1559N of push force at 0.5MPa, making it well-suited for medium-duty automation tasks requiring a substantial extension range. The extruded aluminum barrel design omits tie rods, providing a clean exterior that simplifies mounting and cleaning.
This specific configuration includes a magnet for use with CMSE or DMSE sensor switches fitted into the dual side grooves. The piston rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and fluid supply is routed via PT tapered threads. It is a genuine AirTAC component built for drop-in dimensional interchangeability with other ISO 15552 standard actuators.

Where the Airtac SAI63 Standard Cylinder SAI63AX280S Is Used
Material Handling
Ideal for pushing or diverting packages on conveyor lines where the 1559N thrust at 0.5MPa easily overcomes friction and moves medium-weight goods reliably.
Assembly Automation
Drives clamping and pressing mechanisms in automated stations, utilizing the 280mm stroke to actuate mechanisms requiring extended reach.
Packaging Equipment
Handles product sorting and positioning tasks, benefiting from the dual sensor grooves for precise end-of-stroke detection using CMSE switches.
Is the Airtac SAI63 Standard Cylinder SAI63AX280S the Right Cylinder?
Choose this 63mm bore if your application requires more thrust than the 50mm bore (982N at 0.5MPa) but you do not need the higher force of the 80mm option (2513N at 0.5MPa). The 280mm stroke is fully standard for this bore size. Because the stroke exceeds 300mm, closely evaluate side loads; long unsupported rods are prone to bending and premature rod bearing wear. Using an external guide rail or a dedicated guided cylinder is strongly recommended to prevent rod deflection.
This standard SAI variant does not hold its load when air pressure is removed or exhausted. The adjustable air cushions only decelerate the piston near the stroke ends. If your machinery requires true position holding without live pressure, consider the SAIL locking variant or an external pilot-operated check valve. Replacement installations should match the 63mm bore, 280mm stroke, G3/8 port, and mounting accessories like FA flanges or TC trunnions.
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 SAI63AX280S FAQ
At 0.5MPa operating pressure, this 63mm bore cylinder provides 1559N of push force and 1402N of pull force. At 0.7MPa, the push force increases to 2182N.
Yes, the SAI63X280-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other standard profile cylinders of the same bore and stroke, provided your port and mounting dimensions match.
