The AirTAC Airtac SCD Standard Cylinder SCD160X800 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø40mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø160mm bore, 800mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD160X800 is a large-bore double-rod pneumatic cylinder that outputs an identical 9425 N of thrust in both directions at 0.5 MPa, thanks to its 40 mm rod passing through both end caps. This symmetry eliminates force differentials, making it ideal for large transfer shuttles and tooling that must move a load forward and back with precisely matched power. At the maximum operating pressure of 0.9 MPa, the force rises to 16964 N each way.
With an 800 mm stroke, this cylinder provides substantial linear travel for material handling and heavy-duty positioning tasks. The body length A(SCD) is 352 mm, and the adjustable pneumatic cushion at each end is 29 mm long, providing smooth deceleration for high-inertia loads. This model is a genuine AirTAC tie-rod cylinder, built for reliable double-ended actuation in demanding industrial environments.

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 | 9425 N | 9425 N |
| 0.7 MPa | 13195 N | 13195 N |
| Max (@1.0 MPa) | 1922 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 9425 N push/pull force at 0.5 MPa moves large pallets or weldments between stations with consistent speed and power in both directions, preventing the drift common with unequal-area cylinders.
Mount a forming die on the front rod and a stripper plate on the rear rod. The SCD160X800 applies the same 16964 N of force at 0.9 MPa to both operations from a single air circuit.
The 40 mm rear rod provides a convenient mounting point for a DMSG sensor flag to confirm full retraction, while the front rod pushes a finished part off a large press bed with 800 mm of stroke.
Select the SCD160X800 when your application requires a balanced, high-force actuator with a rod on both ends for symmetrical tooling or rear-mounted position sensing. If 9425 N at 0.5 MPa is more force than needed, stepping down to the SCD125 bore provides 5734 N at the same pressure. Conversely, if the 800 mm stroke is near the limit of your guided setup, verify that the unsupported 40 mm rod does not deflect under compression; for long strokes with side loads, a dedicated guided cylinder is a safer choice than relying solely on the double-rod's inherent guidance.
This cylinder is a direct replacement for another AirTAC SCD160 double-rod unit matching the 800 mm stroke, PT port thread, and basic mounting style. If your previous cylinder had a magnet for sensors, ensure you order the -S variant. For applications where force is only needed in one direction, the single-rod SC160 series may offer a simpler, more cost-effective solution.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. The effective piston area is the same on both sides. At 0.5 MPa it produces 9425 N, at 0.7 MPa it is 13194 N, and at the maximum operating pressure of 0.9 MPa, the force is 16964 N in both directions.
Choose the SCD160 when you need perfectly symmetrical force and speed for a reciprocating motion, or when you require a second rod end to mount a sensor cam, a mechanical stop, or secondary tooling. The double-rod design also provides better support for the piston, reducing bearing wear in applications with slight side loads, though it is not a substitute for a fully guided cylinder under high lateral forces.
