The AirTAC Airtac SCD Standard Cylinder SCD160X80 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, 80mm stroke, PT3/4 ports and adjustable end cushioning.
The SCD160X80 is a double-acting, double-rod pneumatic cylinder that provides identical push and pull force of 9425 N at 0.5 MPa, thanks to its through-rod design which subtracts the Ø40 mm rod area from both sides equally. With an 80 mm stroke and a body length A of 352 mm, it fits compact two-sided tooling stations where space is tight but high force is non-negotiable.
Both rod ends protrude, allowing you to mount tooling on the front and a stopper or sensor flag on the rear, while the adjustable air cushion (29 mm length) decelerates the 160 mm bore piston smoothly. This genuine AirTAC SCD cylinder operates on 40 µm filtered air from 0.15 to 1.0 MPa and uses PT3/4 ports.

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 SCD160X80 applies equal 9425 N clamping force from both rod ends simultaneously, perfect for weld fixtures or assembly jigs that must grip a workpiece from opposite sides with balanced pressure.
With a through rod, you can drive a scissor lift mechanism from one end and attach a counterbalance or limit switch dog to the rear, keeping the 160 mm bore cylinder's motion synchronized and guided.
Use the front rod to push a pallet onto a conveyor and the rear rod extension to trigger a proximity sensor, confirming the 80 mm stroke is complete before the next cycle begins.
Choose the SCD160X80 when you need equal bidirectional force around 9425 N at 0.5 MPa. If your application requires less thrust, step down to the SCD125 bore (5734 N at 0.5 MPa); for significantly more, the SCD200 bore offers 15080 N. This double-rod unit is ideal for symmetric actuation, but if you only need force from one end, a single-rod SC160 cylinder is a simpler and more economical choice.
To replace an existing SCD160X80, match bore (160), stroke (80), PT3/4 port thread, basic mounting, and the absence of a magnet. For strokes longer than 300 mm on this bore, evaluate the unsupported rod length under compression to avoid buckling—an external guide rail or a guided cylinder may be required.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 9425 N, at 0.7 MPa it produces 13194 N, and at the maximum operating pressure of 0.9 MPa it delivers 16964 N in both directions.
Choose the SCD160 when you need equal force and speed in both directions, or when you need to attach tooling, a sensor flag, or a mechanical stop to the rear rod end. The through rod also provides better bearing support and inherent anti-rotation compared to a single-rod cylinder, though it is not a substitute for an externally guided unit under high side loads.
