About the Airtac SAI63 Standard Cylinder SAI63X240S
The AirTAC SAI63X240-S is a double-acting ISO 15552 profile cylinder offering a 63mm bore and 240mm stroke. It generates 1559 N of push force and 1402 N of pull force at 0.5 MPa, making it well-suited for mid-range industrial handling tasks that require a specific intermediate stroke length.
This variant includes an integrated magnet (-S) for direct compatibility with CMSE and DMSE series reed switches, which mount easily into the dual sensor grooves machined into the extruded aluminum barrel. The piston rod uses standard carbon steel, and the tapered PT port threads ensure a tight, reliable pneumatic connection.

Where the Airtac SAI63 Standard Cylinder SAI63X240S Is Used
Component Clamping
Provides 1559 N of clamping force at 0.5 MPa to hold medium-sized metal or plastic workpieces securely during CNC machining and drilling operations.
Package Diverting
The 240mm stroke actuates diverter arms on conveyor lines to route medium-weight cardboard cartons to specific packing zones.
Pneumatic Pressing
Applies steady downward pressure for light-duty assembly tasks, such as pressing bearings into housings or securing snap-fit components.
Is the Airtac SAI63 Standard Cylinder SAI63X240S the Right Cylinder?
Choose this 63mm bore when a 50mm bore (982 N push at 0.5 MPa) is insufficient, but an 80mm bore (2513 N push at 0.5 MPa) would physically overpower the application and waste compressed air. The 240mm stroke provides ample travel for packaging and material transfer tasks. To guarantee a true drop-in replacement, verify the ISO 15552 mounting dimensions, the G3/8 port, and your required mounting accessory (such as an FA flange or TC trunnion) before finalizing the RFQ.
Because the stroke exceeds 300mm? No, but at 240mm, you should still be mindful of side loads. For applications involving heavy off-center loads, use external guide rails or a dedicated guided cylinder to prevent rod-bearing bending and premature seal wear. Note that a standard SAI cylinder will drift if air pressure is lost; if the mechanism requires fail-safe position holding, select the SAIL (air-released lock) variant or an external rod lock.
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.
