About the Airtac SAID63 Double Rod Cylinder SAID63X140S
The AirTAC SAID63X140-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a through-rod design where a single piston drives rods out of both end covers. Because the annulus area is identical on both sides, it generates an equal 1402 N of force in both extend and retract directions at 0.5 MPa. The included -S magnet enables precise position sensing using AirTAC CMSE reed or DMSE solid-state switches along the dual-side sensor grooves.
Equipped with a 20mm carbon steel rod and M16x1.5 rod thread, this 63mm bore variant uses a G3/8 port and offers adjustable air cushioning at both ends to decelerate the piston smoothly. The twin-rod architecture provides superior anti-rotation guidance and allows the rear rod to operate a secondary mechanism or flag. It uses a reduced mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) compared to single-rod SAI types.

| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID63 Double Rod Cylinder SAID63X140S Is Used
Symmetric Force Transfer
Transfers parts with identical 1402 N push and pull forces, ensuring no speed discrepancy between extension and retraction cycles.
Twin-Station Actuation
Drives a primary workpiece on the front rod while simultaneously moving a secondary mechanism or cam from the rear rod end.
Anti-Rotation Slides
Keeps guided loads perfectly stable without rotational drift, utilizing the dual-rod structure to maintain strict linear alignment.
Is the Airtac SAID63 Double Rod Cylinder SAID63X140S the Right Cylinder?
Choose this double-rod configuration over a standard single-rod SAI when your application demands equal push and pull forces, symmetrical speeds, or dual-side guidance to prevent the load from twisting. If you need less force, the 50mm bore neighbor provides 825 N both ways at 0.5 MPa; if your mechanism requires more power, step up to the 80mm bore for 2268 N. This SAID63X140-S variant includes the -S magnet for CMSE / DMSE sensor integration and uses PT threaded ports.
At a 140mm stroke, the overall length is longer than a single-rod cylinder because the rear rod protrudes through the back cover, so ensure you have adequate clearance for the secondary rod end. Remember that a plain SAID does not hold a load when air pressure is lost; if your mechanism needs static holding, consider the SAIL lock or BSAID clamp-lock series. For stroke lengths of 300mm or more, always add an external guide to prevent rod-bearing bending under side loads.

- ✓ 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 SAID63 Double Rod Cylinder SAID63X140S FAQ
It provides 1402 N of force at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa. Because it is a double-rod cylinder, this exact force output is identical in both the extend and retract directions.
Yes, it is dimensionally interchangeable per ISO 15552 profile cylinder standards, making it a direct replacement for other ISO 15552 double-rod cylinders. It uses a standard 20mm rod with an M16x1.5 thread.
