The AirTAC Airtac SCD Standard Cylinder SCD32X300 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, 300mm stroke, PT1/8 ports and adjustable end cushioning.
The SCD32X300 is a double-acting, double-rod pneumatic cylinder that outputs an identical 345 N of force in both the extend and retract directions at 0.5 MPa, thanks to its 12 mm through-rod. This symmetry eliminates force differentials, making it ideal for applications where a tool or sensor flag must be mounted on the rear rod end.
With a 300 mm stroke, this model stays within the 1000 mm maximum standard stroke for the 32 mm bore. The cylinder body has a baseline length of 187 mm (A dimension), and the adjustable air cushion at each end provides a 21 mm deceleration zone to manage end-of-stroke impact without requiring external shock absorbers.

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 through-rod design allows a tool or fixture to be mounted on both ends of the cylinder, performing work in both directions with equal 345 N force at 0.5 MPa.
Attach a sensor flag or cam to the rear rod to trigger external limit switches, keeping the front working area clear of sensor mounting brackets.
The dual-rod support provides enhanced guidance, helping to prevent piston rod rotation during a 300 mm linear push in light-duty sorting or diverting tasks.
Choose the SCD32X300 when your mechanism needs equal bidirectional thrust and a rear rod extension for mounting a cam, stopper, or external sensor flag. If 345 N at 0.5 MPa is insufficient, stepping up to the SCD40 bore provides 528 N of force in both directions. For applications that only require a working rod on one end, the single-rod SC series is a simpler and more cost-effective alternative.
For a direct replacement, match the 32 mm bore, 300 mm stroke, PT port thread, and basic mounting configuration. If you are adding a built-in magnet for position sensing, specify the -S suffix. At this 300 mm stroke length, ensure any side load on the exposed rear rod is minimal; an external guide rail is recommended if the rod must support a transverse load.
Double-rod checklist
Because it is a double-rod cylinder, the effective piston area is the same on both sides. The SCD32X300 delivers 345 N in push and 345 N in pull at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at the maximum operating pressure of 0.9 MPa.
Select the SCD when you need equal force and speed in both directions, or when you require a rear rod extension to mount tooling, a mechanical stop, or a sensor target. The through-rod also provides better guidance than a single-rod cylinder, though it is not a replacement for a fully guided unit under high side loads.
