Airtac SCD Standard Cylinder SCD63X560TC
The AirTAC Airtac SCD Standard Cylinder SCD63X560TC is a genuine double-acting DOUBLE-ROD air cylinder: the Ø20mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø63mm bore, 560mm stroke, PT1/4 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD63X560TC
The AirTAC SCD63X560TC is a double-acting, double-rod pneumatic cylinder that delivers perfectly symmetrical force and speed in both directions, outputting 1402 N of thrust at 0.5 MPa. With a 63 mm bore, a 20 mm rod protruding from both end caps, and a 560 mm stroke, this model is built for applications requiring bilateral tooling or a rear rod for mounting sensors and stops.
This configuration includes a centre trunnion (TC) mount, allowing the cylinder body to pivot as the load moves through an arc, which is essential for preventing rod bending in guided linkages. The adjustable air cushion at each end cap (28 mm length) decelerates the piston smoothly, and the PT1/4 ports ensure straightforward integration with standard pneumatic circuits.

| Stroke | 560 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT1/4 |
| Rod thread | M16×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
Specifications follow the official AirTAC SCD (double-rod) datasheet. Because the rod runs through both caps, the effective area is (bore² − rod²) in both directions. Confirm against the product label before installation. Thread options: PT (standard) / G.
Theoretical Output Force (Ø63mm, double rod)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 1402 N | 1402 N |
| 0.7 MPa | 1962 N | 1962 N |
| Max (@1.0 MPa) | 286 kgf | |
Push and pull are EQUAL on a double-rod cylinder — both chambers lose the rod area, so effective area = (bore² − rod²) each way. Actual usable force is lower than theoretical due to friction and back-pressure; size with a safety margin.

Where the Airtac SCD Standard Cylinder SCD63X560TC Is Used
Bilateral Transfer Shuttles
The through-rod design allows tooling to be mounted on both ends, enabling the cylinder to push a workpiece into a station while simultaneously pulling the next one into position, doubling throughput in a single stroke.
Non-Rotating Pushers
With a rod supported by bearings in both end caps, the SCD63X560TC offers superior resistance to rod rotation compared to a single-rod cylinder, making it ideal for pushing loads where maintaining angular alignment is critical.
Pivoting Conveyor Gates
The centre trunnion mount allows the entire 560 mm stroke cylinder to swing freely, perfectly matching the arc of a diverter gate on a conveyor line without imposing bending stress on the piston rod.
Is the Airtac SCD Standard Cylinder SCD63X560TC the Right Cylinder?
Choose the SCD63 bore when your application needs around 1400 N of balanced force in both directions at standard plant pressure. If you require more thrust, the SCD80 delivers 2268 N at the same 0.5 MPa, while stepping down to the SCD50 provides 825 N. For this 560 mm stroke, be mindful of the long, unsupported 20 mm rod extending from both ends; if the load applies any significant side force, an external guide rail or a switch to a guided cylinder is mandatory to prevent rod buckling and premature seal wear.
This SCD63X560TC is a direct dimensional replacement for an existing AirTAC SCD63 cylinder of the same 560 mm stroke, provided the original also uses a centre trunnion mount, PT ports, and no magnet. The trunnion bracket (F-SC63TC) is included, enabling a drop-in swap in pivoting applications.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCD Standard Cylinder SCD63X560TC FAQ
Because the piston rod runs through both ends of the cylinder, the effective pressure area is identical for both directions. The output force is 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at the maximum operating pressure of 0.9 MPa.
Select the SCD when you need equal force and speed in both directions, or when you require a rear rod extension to mount a limit switch cam, a mechanical stop, or secondary tooling. The dual-bearing support also provides better guidance against rod deflection than a single-rod cylinder, though it is not a substitute for a fully guided actuator under heavy side loads.
