The AirTAC Airtac SCD Standard Cylinder SCD32X450 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, 450mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X450 is a double-acting, double-rod pneumatic cylinder that provides identical thrust in both directions—345 N at 0.5 MPa—because the 12 mm rod passes through both end caps. With a 450 mm stroke, it is well within the 1000 mm maximum standard stroke for the 32 mm bore, making it a readily available length for applications needing a through-rod design.
This model features a 187 mm body length (A dimension) and adjustable air cushioning over the final 21 mm of travel to decelerate the piston smoothly. The M10x1.25 rod threads on both ends let you mount tooling, stops, or sensor flags on either side, while the PT1/8 ports supply the dual air chambers.

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 equal push/pull force of 345 N at 0.5 MPa and dual-ended rod make it ideal for small part shuttles where a tool is mounted on each end, moving workpieces between two stations with one actuator.
The through-rod design provides inherent anti-rotation stability. Use the rear rod extension with an external guide block to prevent piston rod rotation without adding a full guided cylinder.
Mount a sensor flag on the rear M10x1.25 rod end to trigger a limit switch, while the front rod performs the main work. This keeps the sensing mechanism clear of the primary tooling area.
Choose the SCD32X450 when you need equal force and speed in both directions from a compact cylinder. If 345 N at 0.5 MPa is insufficient, stepping up to the SCD40 bore provides 528 N under the same pressure. For applications where the rear rod is unnecessary, a single-rod SC32 cylinder offers a higher push force from the full piston area. This SCD model is a direct replacement for an existing AirTAC SCD32X450 with PT ports and basic mounting; ensure the bore, stroke, and port thread match exactly.
Double-rod checklist
The push and pull forces are identical because the rod passes through both ends. The effective piston area is the bore minus the 12 mm rod. The force is 345 N at 0.5 MPa, 483 N at 0.7 MPa, and reaches 621 N at the maximum operating pressure of 0.9 MPa.
Choose the SCD when you need a rear rod extension for mounting a stopper, cam, or sensor flag, or when you require perfectly equal force and speed in both directions. A single-rod SC cylinder has a higher push force due to the full piston area, but its pull force is reduced by the rod area, creating an imbalance.
