The AirTAC Airtac SCD Standard Cylinder SCD80X470 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø80mm bore, 470mm stroke, PT3/8 ports and adjustable end cushioning.
The SCD80X470 double-rod pneumatic cylinder provides a balanced 2268 N of thrust in both directions at 0.5 MPa, rising to 4082 N at 0.9 MPa, because the 25 mm rod passes through both end caps and subtracts the same area from each side. This symmetry eliminates force differentials, making the cylinder ideal for applications where a rear rod extension carries a limit switch flag, a secondary tool, or a manual override handle.
With a 470 mm stroke, this 80 mm bore model stays within the standard stroke range for its size, which extends up to 1500 mm. The tie-rod construction houses an adjustable air cushion (28 mm length) at each end to decelerate the piston quietly, while the PT3/8 ports and M20x1.5 rod threads provide straightforward pneumatic connections and tooling attachment on both ends.

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.
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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.

The 470 mm stroke with a rod on each end allows a single cylinder to power a reciprocating shuttle table, moving a fixture between two stations with perfectly matched speed and force in both directions.
Use the rear rod extension to mount a cam or flag that trips external limit switches, providing direct, mechanical end-of-stroke confirmation without needing to sense the piston magnetically through the barrel.
Attach a primary tool to the front rod and a secondary mechanism, like a stripper plate or ejector, to the rear rod. Both tools cycle in perfect mechanical synchronization from a single SCD80X470 cylinder.
Choose the SCD80X470 when you need identical push and pull force from both rod ends. If your load requires less force, the 63 mm bore SCD series delivers 1402 N at 0.5 MPa; for heavier tooling, stepping up to the 100 mm bore provides 3681 N. If you only need force from one end, a single-rod SC cylinder is a simpler and more compact alternative. For a drop-in replacement, match the 80 mm bore, 470 mm stroke, PT3/8 port thread, and the basic mounting configuration of this model.
At a 470 mm stroke, the unsupported rod length on each side becomes a consideration. While the double-rod design offers better guidance than a single rod, sustained side loads can still cause rod bending or seal wear. For applications with off-axis forces, consider adding an external guide rail or switching to a guided cylinder assembly.
Double-rod checklist
The push and pull forces are identical because the piston rod extends through both ends of the cylinder. At 0.5 MPa, the force is 2268 N in each direction. This increases to 3175 N at 0.7 MPa and reaches 4082 N at the maximum operating pressure of 0.9 MPa.
You would choose the SCD80X470 when you need a rear rod extension for mounting sensors, cams, or secondary tooling, or when your application demands perfectly balanced force and speed in both directions. The through-rod design also provides better support for the piston, reducing uneven bushing wear compared to a single-rod cylinder under certain conditions.
