The AirTAC Airtac SCD Standard Cylinder SCD80X80 is a genuine double-acting DOUBLE-ROD air cylinder: the Ø25mm piston rod extends from BOTH end caps, giving equal effective area — and therefore equal force — in push and pull. Ø80mm bore, 80mm stroke, PT3/8 ports and adjustable end cushioning.
The SCD80X80 is a double-acting, double-rod pneumatic cylinder that outputs an identical 2268 N of force in both directions at 0.5 MPa, thanks to its 25 mm through-rod subtracting the same area from each side. This balanced thrust makes it ideal for tasks where a return stroke must match the power of the advance stroke, such as operating a symmetrical clamping fixture or a two-sided scraper. The 80 mm bore body has a length of 257 mm and uses PT3/8 ports.
With an 80 mm stroke, this model is well-suited for short, repetitive transfer or ejection duties where the rear rod extension can carry a sensor flag or a secondary tool. The adjustable air cushion at each end, with a 28 mm cushion length, decelerates the piston smoothly to reduce end-cap impact. The operating pressure spans 0.15 to 1.0 MPa, and the standard TPU seals work reliably from -20 to +70 °C.

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 | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | 3175 N |
| Max (@1.0 MPa) | 463 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 2268 N push and pull force moves a shuttle table between two stations with perfectly matched speed and power in both directions, simplifying flow control settings.
A tool mounted on the front rod clamps a part while the rear rod simultaneously actuates a locking wedge or a second clamp, all driven by one cylinder with balanced force.
The 25 mm rod protruding from the rear cap provides a convenient mounting point for a sensor flag or cam, enabling end-of-stroke detection without interfering with the main tooling on the front rod.
This 80 mm bore SCD is a step up from the 63 mm size, which provides 1402 N at 0.5 MPa, and a step below the 100 mm bore that delivers 3681 N. Choose the SCD80X80 when your application needs around 2.3 kN of equal push-pull force. If you only require force from one end, a single-rod SC80 cylinder would be a more cost-effective choice, as it provides a higher push force on the full-bore side. For direct replacement, match the 80 mm bore, 80 mm stroke, PT3/8 port thread, and ensure the mounting accessory (if any) is from the SCD subset: basic, FA, LB, or TC.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are identical. At 0.5 MPa it produces 2268 N, at 0.7 MPa it produces 3175 N, and at the maximum operating pressure of 0.9 MPa it produces 4082 N in both directions.
Choose the SCD80X80 when you need equal force and speed on the extend and retract strokes, or when you need a rear rod extension to mount tooling, a stopper, or a sensor flag. The through-rod also provides better guidance and anti-rotation than a single-rod cylinder. If you only need a strong push stroke and a weaker pull stroke, the single-rod SC80 is a simpler option.
