About the Airtac SAID63 Double Rod Cylinder SAID63X80
The AirTAC SAID63X80 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 80mm stroke. Because a rod exits both end covers, the annulus area is identical on extension and retraction, yielding an equal both-way force of 1402N at 0.5 MPa. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This through-rod design allows mounting a primary workpiece on one end while attaching a cam, position flag, or secondary mechanism to the rear rod. It utilizes a standard carbon steel rod and PT tapered port threads, ensuring robust, interchangeable performance for demanding motion control tasks.

| 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 SAID63X80 Is Used
Symmetric Force Transfer
Ideal for pressing or transferring stations where the 1402N output must remain perfectly matched in both advance and retract strokes.
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, providing precise linear guidance for heavy sliding fixtures.
Through-Rod Sensing
Drive the primary load on the front rod while using the rear rod extension to actuate external limit flags or cam mechanisms.
Is the Airtac SAID63 Double Rod Cylinder SAID63X80 the Right Cylinder?
Select this 63mm bore when an application requires balanced bidirectional power and anti-rotation stability that a single-rod SAI cannot provide. If your mechanism needs less force, stepping down to the 50mm bore yields 825N each way at 0.5 MPa; if more thrust is required, the 80mm bore provides 2268N. The SAID series uses a specific mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR accessories.
Ensure your layout accommodates the rear rod protrusion, which requires extra clearance compared to standard single-rod cylinders. Note that the adjustable air cushions only decelerate the piston near stroke end; a plain SAID will not hold a load if air pressure is lost. For position holding without live pressure, consider a SAIL lock or BSAID clamp-lock cylinder.
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 SAID63X80 FAQ
Because the double-rod design equalizes the piston area on both sides, the extend and retract forces are identical. It provides 1402N at 0.5 MPa, 1962N at 0.7 MPa, and 2523N at 0.9 MPa in both directions.
Yes. The SAID63X80 is dimensionally interchangeable per ISO 15552 profile standards, meaning it serves as a direct replacement for other ISO 15552 double-rod cylinders, utilizing the same mounting interface and PT port size.
