About the Airtac SAID63 Double Rod Cylinder SAID63X80S
The AirTAC SAID63X80-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 80mm stroke. Because a carbon steel piston rod exits both end covers, the effective annulus area is identical on extension and retraction, yielding an equal 1402 N of thrust and pull force at 0.5 MPa. The included magnet (-S) directly supports position detection using AirTAC CMSE reed or DMSE electronic solid-state switches housed in the dual-side sensor grooves.
This twin-rod architecture is purpose-built for applications demanding anti-rotation stability and dual-side functionality. You can mount the primary workpiece on the front rod end while utilizing the rear protrusion to drive a secondary mechanism, mount a cam, or fix a limit flag. It features PT tapered port threads (G3/8) and adjustable air cushions at both ends to decelerate the payload smoothly.

Theoretical Output Force (Ø63mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | — |
| Max (@1.0 MPa) | 286 kgf | |
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 SAID63X80S Is Used
Symmetric Force Transfer
Drives equal push and pull loads of 1402 N at 0.5 MPa without speed variation, ensuring consistent cycle times for pressing and clamping operations.
Anti-Rotation Slides
The twin-rod geometry prevents mechanical twisting under offset loads, providing rigid linear guidance for precision handling and tooling.
Rear-Rod Sensing
Utilizes the rear rod extension to mount a physical cam or limit flag, triggering external sensors while keeping the primary work area clear.
Is the Airtac SAID63 Double Rod Cylinder SAID63X80S the Right Cylinder?
Select this 63mm bore when your mechanism requires symmetric force and speed in both travel directions, offering 1402 N each way at 0.5 MPa. If your application needs less force, the 50mm bore provides 825 N; if you require more thrust, stepping up to the 80mm bore yields 2268 N. The double-rod design is chosen over a single-rod SAI when the load must be guided against rotation or when a rear rod is needed for external tracking.
As a dimensionally interchangeable ISO 15552 component, it serves as a direct replacement for other standard profile cylinders. Ensure you specify the correct mounting accessories from the SAID subset (Basic, FA, LB, TC, FTC, TCM1, TCM2), as rear clevis or trunnion styles are omitted. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load. If air pressure is lost, the cylinder will drift, requiring an external pilot-operated check valve or a BSAID clamp-lock cylinder for true position holding.
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 SAID63X80S FAQ
Because the rod occupies both sides of the piston, the effective area is equal in both directions. The SAID63X80-S generates 1402 N of force both extending and retracting at 0.5 MPa, and 1962 N at 0.7 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 standards and uses a standard profile barrel. It can serve as a direct replacement for other ISO 15552 double-rod cylinders, utilizing mounting accessories like FA, LB, or TC brackets.
