About the Airtac SAI63 Standard Cylinder SAI63AX240S
The AirTAC SAI63X240-S is a double-acting profile cylinder with a 63mm bore and 240mm stroke, delivering a push force of 1559 N at 0.5 MPa. It is built to ISO 15552 dimensional standards, providing a drop-in replacement for any standard ISO 15552 cylinder without altering mounting footprints. The 240mm stroke is ideal for mid-range linear actuation tasks requiring substantial reach.
This specific configuration includes a magnet (-S) for use with CMSE and DMSE series reed or solid-state switches, which mount directly into the dual sensor grooves on the extruded aluminum barrel. The piston rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and it uses PT tapered thread ports.

Where the Airtac SAI63 Standard Cylinder SAI63AX240S Is Used
Material Handling
Ideal for pushing or diverting packages on conveyor lines where a 240mm stroke and 1559 N of force are required to move medium-weight products.
Assembly Station
Drives linear motion in automated assembly equipment, utilizing the integrated magnet for end-of-stroke position sensing with CMSE switches.
Packaging Machinery
Operates clamping and lifting mechanisms in packaging equipment, benefiting from the SUS420J2 stainless steel rod for durability in industrial environments.
Is the Airtac SAI63 Standard Cylinder SAI63AX240S the Right Cylinder?
When selecting this model, consider the force requirements of your application: the 63mm bore provides 1559 N of push force at 0.5 MPa, while stepping down to a 50mm bore yields 982 N. If your application requires higher force, the neighboring 80mm bore offers 2513 N at the same pressure.
Because the 240mm stroke is below the 300mm threshold, standard rod bearing bending is minimal, but side loads should still be minimized or managed with external guides. This cylinder does not hold its position if air pressure is lost; if your application requires fail-safe load holding, consider the SAIL (air-released lock) or BSAI (bidirectional clamp-lock) variants. For direct replacement, match the 63mm bore, 240mm stroke, PT G3/8 port, and required mounting accessories like LB or TC.
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.
