About the Airtac SAI63 Standard Cylinder SAI63X260S
The AirTAC SAI63X260-S is a double-acting ISO 15552 profile cylinder featuring a 63mm bore and a 260mm stroke. It delivers a robust push force of 1559 N at 0.5 MPa, making it well-suited for medium-duty industrial handling and positioning tasks.
This variant includes an integrated magnet for direct mounting of CMSE or DMSE sensor switches along the dual grooves machined into the extruded aluminum barrel. It uses standard carbon steel piston rod material and PT tapered port threads, ensuring reliable sealing and straightforward pneumatic connections.

Where the Airtac SAI63 Standard Cylinder SAI63X260S Is Used
Material Diverting
Actuates diverter arms on packaging lines to route cartons at high speed.
Clamp Actuation
Provides 1559 N of push force at 0.5 MPa to secure workpieces during machining.
Vertical Lifting
Raises lightweight pallets or fixtures through a 260mm travel distance.
Is the Airtac SAI63 Standard Cylinder SAI63X260S the Right Cylinder?
If your application requires slightly less force, stepping down to a 50mm bore yields 982 N at 0.5 MPa, whereas moving up to an 80mm bore provides 2513 N for heavier payloads. At a 260mm stroke, the unsupported rod length is significant; using an external guide rail or a guided cylinder is strongly recommended to prevent rod-bearing bending under side loads.
This 63mm bore utilizes a G3/8 port and M16x1.5 rod thread. As a true ISO 15552 profile cylinder, it serves as a drop-in dimensional replacement for comparable standard interfaces. Note that standard models do not hold loads without live air pressure; for drop prevention, select the SAIL or BSAI locking variant.
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.
