The AirTAC Airtac SCD Standard Cylinder SCD200X160 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. Ø200mm bore, 160mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD200X160 is a heavy-duty double-rod pneumatic cylinder that outputs an identical 15080 N of force in both directions at 0.5 MPa, thanks to its through-rod design where the Ø40 mm rod extends from both end caps. This symmetry eliminates force differential, making it ideal for large-scale tooling that requires balanced thrust and a rear rod end for mounting external flags or limit switches.
With a 160 mm stroke and a body length A(SCD) of 362 mm, this tie-rod cylinder provides a robust platform for demanding industrial tasks. It operates on filtered air up to 1.0 MPa, delivering a substantial 27143 N of thrust at 0.9 MPa, while its 33 mm adjustable air cushion on both ends smoothly decelerates high-inertia loads.

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 | 15080 N | 15080 N |
| 0.7 MPa | 21111 N | 21111 N |
| Max (@1.0 MPa) | 3075 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.

Moves heavy pallets or large components between two parallel conveyor lines with equal speed and force in both directions, using the rear rod for a synchronized sensor flag.
Applies identical clamping pressure from opposing sides in large assembly jigs or composite layup tools, ensuring even force distribution without complex linkages.
Performs a forming operation on one side while the rear rod actuates an ejector or stripper plate, combining two actions in one compact, synchronized cylinder package.
Select the SCD200X160 when your application demands equal, high-force actuation from both ends of the piston. If your force requirement is lower, stepping down to the SCD160 bore reduces output to 9425 N at 0.5 MPa, saving energy and physical space. For applications where only one rod end is needed, the single-rod SC200 series offers a simpler solution, but it will have unequal push/pull forces.
For a direct replacement, match the 200 mm bore, 160 mm stroke, PT port thread, and basic mounting configuration. At this stroke length, the dual-rod design provides better bearing support than a single rod, but for any significant side loading, an external guide rail or a dedicated guided cylinder is mandatory to prevent rod bending and premature seal wear.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 15080 N, at 0.7 MPa it produces 21111 N, and at the maximum operating pressure of 0.9 MPa it delivers 27143 N in either direction.
Choose the SCD200X160 when you need perfectly equal force and speed in both directions, or when you need to attach tooling, a sensor target, or a mechanical stop to the rod on the rear cap side. The through-rod also provides better guidance and anti-rotation than a single-rod cylinder, though it is not a substitute for an external guide under heavy side loads.
