About the Airtac SAID63 Double Rod Cylinder SAID63X300
The AirTAC SAID63X300 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 300mm stroke. Because a 20mm carbon steel rod exits both ends, the annulus area is identical on extend and retract, yielding equal force and speed both directions. It delivers 1402N each way at 0.5 MPa, rising to 1962N at 0.7 MPa.
This through-rod design allows you to mount the primary workpiece on one end while attaching a position flag, cam, or secondary mechanism on the rear rod. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE solid-state switches, though this specific unit lacks the -S magnet. It uses adjustable air cushions at both ends (36mm stroke) to decelerate the piston.

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 SAID63X300 Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull force, ensuring consistent cycle timing without asymmetric speed shifts.
Anti-Rotation Slide
Twin rods prevent the load from twisting during vertical lift, providing rigid guidance for precision sliding mechanisms.
Rear-Sensing Drive
Mounts the primary tool on the front rod while using the rear rod end to trip a limit flag or external sensor.
Is the Airtac SAID63 Double Rod Cylinder SAID63X300 the Right Cylinder?
Choose this 63mm bore when an application requires symmetric force (1402N both ways at 0.5 MPa) and superior anti-rotation guidance compared to a single-rod SAI. If you need less force, the 50mm bore provides 825N; if you need more, step up to the 80mm bore for 2268N. The G3/8 port and M16x1.5 rod thread handle robust pneumatic flow and moderate side loads.
At 300mm stroke, the unsupported rod length increases bending risk on the rod bearing; use an external guide for heavy loads to prevent premature wear. Note that a plain SAID does not hold its position unpowered—air loss causes drift, so use a SAIL or BSAID lock for fail-safe holding. It is dimensionally interchangeable per ISO 15552, using the reduced SAID mounting set: Basic, FA, LB, TC, FTC, TCM1, TCM2.
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 SAID63X300 FAQ
The double-rod design provides equal force both directions. It generates 1402N at 0.5 MPa, 1962N at 0.7 MPa, and 2523N at 0.9 MPa for both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552. It supports the SAID mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, but omits single-rod brackets like FB, CA, CB, and CR.
