The AirTAC Airtac SCD Standard Cylinder SCD200X200S 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, 200mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD200X200S is a heavy-duty double-rod pneumatic cylinder that delivers identical push and pull thrust in both directions, rated at 15080 N at 0.5 MPa. Its 40 mm diameter rod passes through both end caps, creating a balanced force profile that eliminates the output differential common in single-rod designs. This model includes a built-in magnet, allowing CMSG, DMSG, or EMSG sensors to be mounted directly on the tie-rod barrel for precise end-of-stroke or mid-stroke position feedback.
With a 200 mm stroke and a robust body length A of 362 mm, this cylinder is built for applications needing symmetric actuation and high force. The adjustable pneumatic cushion on each end cap, with a 33 mm cushion length, provides smooth deceleration for large moving masses. Operating on filtered air from 0.15 to 1.0 MPa, it can produce up to 27143 N of thrust at 0.9 MPa, making it suitable for heavy pressing, lifting, or transfer tasks where the rear rod can also carry tooling or a sensor flag.

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.

The through-rod design allows a tooling plate or gripper to be mounted on both ends, enabling a single cylinder to shuttle parts between two parallel conveyor lines with equal speed and force.
Delivers a balanced 27143 N of clamping force at 0.9 MPa from both sides, ideal for assembly fixtures where a platen must advance and retract with identical controlled pressure.
The dual-rod guidance resists rotation, and the built-in magnet allows a DMSG sensor on the rear rod to confirm full retraction, making it perfect for pushing heavy loads onto a weigh station or palletizer.
Select the SCD200X200S when your application requires a balanced, high-force output of 15080 N in both directions at standard plant pressure. If you need even more force, the SCD250 bore provides 23562 N at 0.5 MPa. If your task only requires force in one direction, a single-rod SC200 cylinder may be a simpler choice, as it offers a higher push force on the full-bore side. For a direct replacement, match the 200 mm bore, 200 mm stroke, PT port thread, and the built-in magnet; this cylinder is dimensionally identical to any other AirTAC SCD200 of the same configuration.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are equal. The effective piston area is calculated by subtracting the 40 mm rod area from the 200 mm bore area. This results in 15080 N at 0.5 MPa, 21111 N at 0.7 MPa, and 27143 N at the maximum operating pressure of 0.9 MPa.
Choose the SCD200 when you need perfectly symmetrical force and speed in both directions, which is impossible with a single-rod cylinder. The rear rod extension also provides a convenient mounting point for a secondary tool, a mechanical stop, or an external sensor flag, and the dual-rod support offers better resistance to side loads than a single rod alone.
