The AirTAC Airtac SCD Standard Cylinder SCD80X60S 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, 60mm stroke, PT3/8 ports and adjustable end cushioning.
The SCD80X60S is a double-acting, double-rod pneumatic cylinder that delivers perfectly symmetrical force in both directions, producing 2268 N of thrust each way at 0.5 MPa. Its 25 mm diameter rod passes through both end caps, giving you a rear rod extension that can carry a sensor flag, a manual override button, or secondary tooling without adding an external bracket.
This 60 mm stroke model includes a built-in magnet (denoted by the -S suffix), so CMSG, DMSG, or EMSG reed and solid-state sensors clamp directly onto the tie-rod barrel for clean, bolt-free position sensing. The 80 mm bore body has a retracted length of 257 mm (dimension A), and the adjustable pneumatic cushion at each end—28 mm long—smoothly decelerates the piston to reduce end-of-stroke impact.

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 equal force and speed in both directions make the SCD80X60S ideal for shuttle tables that move a fixture between two stations, where consistent cycle time in each direction is critical.
With the built-in magnet and a rear rod extension, you can mount a CMSG sensor on the back side to confirm full retraction, keeping the front rod area clear for the main tooling.
The dual-rod support naturally resists rod rotation better than a single-rod cylinder, helping keep a simple pusher plate aligned without needing an external guide for light, on-axis loads.
Choose the SCD80 when you need balanced push-pull output in the 2.2 kN range at standard plant pressure. If your load requires more force, stepping up to the SCD100 bore delivers 3681 N at the same 0.5 MPa; if you need less, the SCD63 provides 1402 N. Because this is a double-rod cylinder, it is the right pick when you need to mount tooling or a position flag on the rear rod—if you only need force from one end, the single-rod SC80 is a simpler, more compact alternative. For direct replacement, match the 80 mm bore, 60 mm stroke, PT port thread, basic mounting, and the -S magnet option to an identical AirTAC SCD80X60S. At this short 60 mm stroke, rod buckling is not a concern, but the through-rod design still provides better bearing support than a single-rod cylinder of the same size.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 2268 N, at 0.7 MPa it produces 3175 N, and at the maximum operating pressure of 0.9 MPa it delivers 4082 N in both directions.
Pick the SCD when you need a rear rod extension to mount a sensor flag, a manual stop, or secondary tooling, or when you require perfectly equal force and speed in both directions. The through-rod also provides better guidance and anti-rotation support than a single-rod SC, though it is not a replacement for a fully guided cylinder under heavy side loads.
