The AirTAC Airtac SCD Standard Cylinder SCD32X125 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, 125mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X125 is a compact double-acting, double-rod pneumatic cylinder that delivers identical push and pull force of 345 N at 0.5 MPa, thanks to its 12 mm rod passing through both end caps. With a 125 mm stroke and a body length A of 187 mm, it is a space-efficient solution for light-duty applications needing a rod on both sides.
Its through-rod construction provides inherent anti-rotation and better bearing support than a single-rod cylinder, making it suitable for tasks where the rear rod can carry a sensor flag or a small stopper. The adjustable air cushion (21 mm) decelerates the piston smoothly at both ends, and the PT1/8 ports keep plumbing simple for compact machine layouts.

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.

Operates a clamp on the front rod while the rear rod triggers a limit switch, synchronizing mechanical action and electrical feedback without extra linkages.
The dual-rod design resists piston rotation, making it suitable for pushing small components onto a conveyor where orientation must be maintained.
Moves a small pallet between two stations with equal speed and force in both directions, simplifying pneumatic circuit design for a 345 N load.
Choose the SCD32X125 when you need equal bidirectional output in a small footprint. If 345 N per direction is insufficient, stepping up to the SCD40 bore provides 528 N at the same 0.5 MPa. For applications where only one rod end is needed, the single-rod SC32X125 is a more economical choice. When replacing an existing unit, match the 32 mm bore, 125 mm stroke, PT port thread, basic mounting, and confirm whether a magnet is required. For strokes of 300 mm or more, consider an external guide to protect the rod from bending under side load.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. 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 reaches 621 N in both directions.
Pick the SCD when you need equal force and speed in both directions, or when the rear rod extension is useful for mounting a sensor target, a mechanical stop, or a secondary tool. The through-rod also provides better guidance and anti-rotation than a standard single-rod cylinder.
