The AirTAC Airtac SCD Standard Cylinder SCD32X460S is a genuine double-acting DOUBLE-ROD air cylinder: the Ø12mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø32mm bore, 460mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X460S is a double-acting, double-rod pneumatic cylinder where the 12 mm piston rod extends from both ends, giving you identical push and pull force in each direction. At 0.5 MPa air pressure, this model outputs a balanced 345 N of thrust both ways, making it ideal for symmetrical transfer tasks where a rear rod connection point is needed for a sensor flag or secondary tooling.
This 32 mm bore unit comes with a built-in magnet (-S suffix), so you can directly mount CMSG, DMSG, or EMSG reed or solid-state sensors on the tie-rod barrel for end-of-stroke detection without extra brackets. With a 460 mm stroke, it remains within the 1000 mm maximum standard stroke for this bore, and the adjustable air cushion at each end (21 mm length) helps decelerate the piston smoothly.

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 | 346 N | 346 N |
| 0.7 MPa | 484 N | 484 N |
| Max (@1.0 MPa) | 70 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 rod out both ends lets you mount a gripper on one side and a counterbalance or secondary tool on the other, perfect for shuttling parts between two stations with equal force in both directions.
With the built-in magnet, CMSG or DMSG sensors clamp directly to the tie-rods to detect piston position. The rear rod can also carry a physical flag for a secondary limit switch.
The dual-rod design inherently resists rotation better than a single-rod cylinder, making it suitable for light pushing or ejecting tasks where you need to keep a tool aligned without a full guided unit.
For a step up in force, the 40 mm bore SCD delivers 528 N at the same 0.5 MPa, while a step down is not available below 32 mm in this series. If your application only needs force from one side, a single-rod SC cylinder would be a simpler, more cost-effective choice, as the double-rod design is specifically for tasks requiring a rear rod extension. For direct replacement, match the 32 mm bore, 460 mm stroke, PT port thread, basic mounting style, and the -S magnet option to ensure sensor compatibility.
At this 460 mm stroke length, be mindful of the unsupported rod on the rear side; while the through-rod provides better guidance than a single rod, it is not designed to take significant side loads. For applications pushing an off-centre mass, consider adding an external guide rail or switching to a guided cylinder to prevent rod bending.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are equal. At 0.5 MPa it produces 345 N, at 0.7 MPa it produces 483 N, and at the maximum operating pressure of 0.9 MPa it produces 621 N in both directions.
Choose the SCD when you need a rear rod extension to mount tooling, a sensor flag, or a mechanical stop. It also provides equal force and speed in both directions and better inherent rod guidance than a single-rod SC, though it is not a substitute for a fully guided cylinder under heavy side loads.
