The AirTAC Airtac SCD Standard Cylinder SCD160X200 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, 200mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD160X200 is a heavy-duty double-rod pneumatic cylinder that outputs an identical 9425 N of thrust in both extend and retract directions at 0.5 MPa, rising to 16964 N at the maximum operating pressure of 0.9 MPa. Its 40 mm diameter piston rod passes completely through both end caps, creating a symmetric force profile that eliminates the pull-side force reduction found in single-rod designs. This model uses a PT3/4 port and features a 29 mm adjustable air cushion to decelerate the 160 mm bore piston smoothly.
With a 200 mm stroke, this cylinder is well within the 1500 mm maximum standard stroke for the 160 bore, making it a readily available configuration. The double-rod construction provides inherent anti-rotation and better rod guidance than a single-rod cylinder, making it suitable for applications where the rear rod extension carries a sensor flag, a mechanical stop, or secondary tooling. The body length A(SCD) is 352 mm, and the overall retracted length is longer than the equivalent single-rod SC model due to the rod protruding from both ends.

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 force in both directions makes the SCD160X200 ideal for heavy transfer shuttles that must move a pallet or fixture between two stations with identical speed and power, using the rear rod for a counterbalance or secondary guide.
Use the through-rod design for a press or clamp that requires tooling on both ends of the cylinder, or where the rear rod extension acts as a visual stroke indicator and a mount for a DMSG sensor to confirm full retraction.
Mount a forming die on the front rod and a stripper plate on the rear rod. The SCD160X200's 40 mm through rod provides robust, guided motion for synchronized dual-action tooling without needing a complex linkage.
Select the SCD160X200 when your application requires equal, high-force actuation in both directions without the complexity of compensating for differential areas. If you need less force, stepping down to the SCD125 bore provides 5734 N at 0.5 MPa. For applications that only require a single working end, the standard SC single-rod cylinder is a more compact and economical choice. As a direct replacement, match the 160 mm bore, 200 mm stroke, PT3/4 port thread, SCD mounting accessory, and optional magnet suffix (-S) to ensure dimensional and performance interchangeability with an existing AirTAC SCD unit.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa, the force is 9425 N; at 0.7 MPa, it is 13194 N; and at the maximum operating pressure of 0.9 MPa, it reaches 16964 N. The theoretical force at 1.0 MPa is 1922 kgf.
Choose the SCD160X200 when you need perfectly equal force and speed in both directions, a rear rod extension for mounting sensors or tooling, or the improved bearing support that a through-rod provides. If your application only needs force from one end and space is a constraint, the single-rod SC160 series is a more compact alternative.
