About the Airtac SAID63 Double Rod Cylinder SAID63X50S
The AirTAC SAID63X50-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a magnetic piston. Because a rod extends from both end covers, the annulus area is identical on both sides, yielding exactly 1402 N of output force in both extend and retract directions at 0.5 MPa. The 50 mm stroke keeps the overall length compact while providing robust dual-side actuation.
This through-rod architecture allows you to mount the primary workpiece on the front rod and a position flag or cam on the rear rod. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet works seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches for precise end-of-stroke detection.

| 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 SAID63X50S Is Used
Symmetric Force Transfer
Ideal for moving parts between two stations where the 1402 N thrust must remain perfectly identical in both directions without reconfiguring pressure.
Anti-Rotation Slides
The twin-rod design naturally resists torsional deflection, keeping guided loads stable and preventing binding on shorter 50 mm strokes.
Dual-Side Actuation
Drive a primary tool on the front rod while using the rear extension to mechanically trigger a DMSE sensor or operate a secondary mechanism.
Is the Airtac SAID63 Double Rod Cylinder SAID63X50S the Right Cylinder?
Select this 63 mm bore when an application demands equal push and pull forces, which is essential for symmetric transfer tasks where a standard single-rod SAI cylinder would create unbalanced thrust. If your mechanism requires less force, stepping down to the 50 mm bore provides 825 N each way at 0.5 MPa; if more thrust is needed, the 80 mm bore offers 2268 N. The PT tapered port threads (G3/8) and carbon steel rod provide a durable, leak-free connection for general pneumatic setups.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders, making it a direct replacement. The available mounting accessories include Basic, FA, LB, TC, FTC, TCM1, and TCM2. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; this cylinder does not hold position if air pressure is lost. For load-holding requirements, consider a SAIL or BSAID 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.
Airtac SAID63 Double Rod Cylinder SAID63X50S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 1402 N in both directions at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
Yes, the SAID63X50-S shares the exact ISO 15552 mounting interface and dimensions, allowing it to serve as a direct replacement for comparable double-rod profile cylinders.
