About the Airtac SAI63 Standard Cylinder SAI63AX270S
The AirTAC SAI63X270-S is a double-acting ISO 15552 profile cylinder engineered to deliver 1559 N of push force at 0.5 MPa and 2182 N at 0.7 MPa. Its 270 mm stroke is ideal for medium-travel automation tasks requiring consistent linear motion. The extruded aluminum barrel design eliminates protruding tie rods, providing a clean exterior that resists dust accumulation.
This specific configuration includes a magnetic piston (-S) for seamless integration with CMSE or DMSE reed switches along the dual sensor grooves. Furthermore, the piston rod is constructed from SUS420J2 stainless steel (material code A), offering excellent corrosion resistance and durability for harsher industrial environments.

Where the Airtac SAI63 Standard Cylinder SAI63AX270S Is Used
Automated Clamping
Secures heavy metal workpieces during CNC machining, utilizing the 2182 N push force at 0.7 MPa to hold parts rigidly against cutting forces.
Package Diverting
Actuates routing arms on packaging lines, where the 270 mm stroke provides sufficient travel to push products cleanly between parallel conveyor belts.
Material Lift Gates
Operates intermediate lifting flaps in bulk material hoppers, benefiting from the SUS420J2 stainless steel rod in mildly dusty or humid environments.
Is the Airtac SAI63 Standard Cylinder SAI63AX270S the Right Cylinder?
Selecting this 63 mm bore cylinder is appropriate when your application requires thrust beyond the 982 N (at 0.5 MPa) provided by a 50 mm bore, but you want to avoid the larger footprint and 2513 N output of an 80 mm variant. The PT (tapered) G3/8 port matches the standard airflow requirements for this bore size.
Because the 270 mm stroke approaches the upper limits of standard unsupported rod lengths, verify that your load is guided externally to prevent rod-bearing bending and premature seal wear. For any mechanism that must maintain its position after air pressure is removed or exhausted, note that the standard adjustable air cushions only decelerate the piston at stroke end; you must employ an external pilot-operated check valve or select the SAIL (air-released lock) variant to prevent drift or drop.
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 SAI63AX270S FAQ
At 0.5 MPa, the cylinder provides 1559 N of push force and 1402 N of pull force. At 0.7 MPa, the push force increases to 2182 N.
Yes, the SAI63X270-S is dimensionally interchangeable per ISO 15552. You can drop it in as a replacement for other ISO 15552 profile cylinders, provided your mounting accessories and PT G3/8 port connections match.
