About the Airtac SAI63 Standard Cylinder SAI63AX260S
The AirTAC SAI63X260-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. This 260 mm stroke length is optimal for mid-range linear actuation tasks requiring substantial reach without compromising cycle times. As a standardized profile barrel design, it offers a true drop-in replacement for other ISO 15552 cylinders.
This specific configuration includes a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance in humid environments. The integrated -S magnet works seamlessly with CMSE and DMSE sensor switches fitted into the dual-side sensor grooves on the extruded aluminum barrel. It also features PT tapered port threads and adjustable air cushions at both ends to manage end-of-stroke impact.

Where the Airtac SAI63 Standard Cylinder SAI63AX260S Is Used
Automated Assembly Presses
Provides 2182 N of thrust at 0.7 MPa for pressing bearings, pins, and bushings into housings on high-speed assembly lines.
Material Diverting
Actuates diverter arms and sorting gates across 260 mm of travel to route packages on conveyor systems efficiently.
Clamping Fixtures
Secures heavy workpieces during machining operations, utilizing the SUS420J2 rod to resist moisture in coolant-rich environments.
Is the Airtac SAI63 Standard Cylinder SAI63AX260S the Right Cylinder?
Selecting this 63 mm bore over the smaller 50 mm bore yields a significant thrust upgrade, pushing 1559 N instead of 982 N at 0.5 MPa. If your application requires less force and faster cycling, stepping down to the 40 mm bore (628 N at 0.5 MPa) is a viable alternative. The 260 mm stroke falls below the 300 mm side-load threshold, but operators should still ensure axial alignment to prevent premature rod-bearing wear.
For installations needing position holding without continuous air pressure, note that the standard SAI cushion only decelerates the piston and does not lock the load. In such cases, consider the SAIL variant with an air-released lock or the BSAI bidirectional clamp-lock. To ensure exact ISO 15552 mounting interface compatibility, pair this cylinder with FA/FB flange or TC trunnion accessories and use G3/8 porting.
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 SAI63AX260S FAQ
At a standard operating pressure of 0.7 MPa, this 63 mm bore cylinder generates 2182 N of push force and 1402 N of pull force. The theoretical maximum force at 1.0 MPa is 318 kgf.
Yes, the -S suffix indicates this model includes a magnet for position sensing. You can mount CMSE or DMSE switches directly into the sensor grooves machined into both sides of the aluminum profile barrel.
