The AirTAC Airtac SCD Standard Cylinder SCD200X1000 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, 1000mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD200X1000 is a heavy-duty double-rod pneumatic cylinder engineered for applications demanding identical thrust in both directions. At 0.5 MPa it produces a substantial 15080 N of force whether extending or retracting, thanks to the Ø40 mm rod passing through both end caps. This 200 mm bore model uses a PT3/4 port and features a 33 mm adjustable air cushion to decelerate large inertial loads smoothly.
With a 1000 mm stroke and a body length A of 362 mm, this tie-rod cylinder provides a long, guided linear motion where the rear rod can carry a secondary tool, counterbalance, or sensor flag. The through-rod design improves bearing support and resists rotation better than a single-rod cylinder of comparable size, making it suitable for large transfer systems and symmetrical pressing operations.

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 fixtures between two stations with equal speed and force in both directions, using the rear rod for a counterbalance or secondary limit switch.
Applies 27143 N of clamping force at 0.9 MPa from either end, ideal for assembly jigs where the tooling is mounted on both sides of a central fixture.
The dual-rod guidance and 1000 mm stroke suit lifting and pushing wide panels or sheets, preventing the twisting that a single-rod cylinder would experience.
Select the SCD200X1000 when your application needs equal bidirectional force and a stroke up to 1500 mm. If 15080 N at 0.5 MPa exceeds your requirement, consider stepping down to the SCD160 bore, which provides 9425 N at the same pressure. For applications that only need force in one direction, the single-rod SC200 series offers a higher push force by using the full piston area, but its pull force will be significantly lower.
For this 1000 mm stroke length, carefully evaluate the potential for rod bending under compressive load. The Ø40 mm through-rod offers good rigidity, but for high side loads or precise guiding over this distance, an external linear guide or a dedicated guided cylinder is recommended. To replace an existing unit, match the 200 mm bore, 1000 mm stroke, PT3/4 port thread, and ensure any mounting accessories like an FA flange or TC trunnion are identical.
Double-rod checklist
The push and pull forces are identical because the rod passes through both ends. At 0.5 MPa it is 15080 N, at 0.7 MPa it is 21111 N, and at the maximum operating pressure of 0.9 MPa it reaches 27143 N. The theoretical force at 1.0 MPa is 3075 kgf.
Choose the SCD when you need equal force and speed in both directions, or when you need to mount a tool, sensor, or stop on the rear rod. The through-rod also provides better guidance and anti-rotation properties than a single-rod SC cylinder, making it more stable for unsupported loads, though it is not a replacement for a fully guided cylinder under high side loads.
