About the Airtac SAID63 Double Rod Cylinder SAID63X450
The AirTAC SAID63X450 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 63mm bore and 450mm stroke. Because a carbon steel rod exits both ends, the effective piston area is identical in each direction, yielding perfectly balanced thrust of 1402N at 0.5MPa and 1962N at 0.7MPa on extend and retract. A single piston carries power to both end covers, making it dimensionally interchangeable with other ISO 15552 twin-rod units.
This through-rod design allows you to mount the primary workpiece on one end while attaching a position flag, cam, or secondary mechanism to the rear rod. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches, and adjustable air cushions at both ends absorb end-of-stroke impact.

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 SAID63X450 Is Used
Symmetric Force Transfer
Drives push and pull operations requiring identical 1402N force at 0.5MPa, ensuring consistent cycle times and torque in both directions without pressure compensation.
Anti-Rotation Slides
The twin through-rods prevent piston twisting under offset loads, providing precise linear guidance for machining and assembly fixtures.
Dual-Station Actuation
Mount a workpiece on the front rod end and a cam or position flag on the rear rod end to operate two mechanisms or trigger two sensor arrays simultaneously.
Is the Airtac SAID63 Double Rod Cylinder SAID63X450 the Right Cylinder?
Select this 63mm bore when an application requires equal push and pull forces, superior anti-rotation guidance, or dual-side actuation. If your project demands less force, the 50mm bore offers 825N each way at 0.5MPa; if you need more thrust, the 80mm bore provides 2268N both directions. The SAID series utilizes a specific mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting the FB, CA, CB, and CR brackets found on single-rod SAI models.
With a 450mm stroke, the unsupported rod length increases, raising the risk of side-load bending on the rod bearing; utilize an external guide for heavy radial loads. Note that a plain SAID63X450 will drift if air pressure is lost or the valve is centered, as the cushions only decelerate the piston and do not hold the load. For position holding without live pressure, consider an external rod lock, a SAIL pneumatic lock, or a BSAID clamp-lock cylinder.

- ✓ 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 SAID63X450 FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It generates 1402N both ways at 0.5MPa, 1962N at 0.7MPa, and 2523N at 0.9MPa.
Yes, the SAID63X450 is dimensionally interchangeable per ISO 15552 mounting interface standards. It uses a PT G3/8 port and a 20mm rod, making it a direct replacement for other standard ISO 15552 profile twin-rod cylinders.
