The AirTAC Airtac SCD Standard Cylinder SCD80X560S 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, 560mm stroke, PT3/8 ports and adjustable end cushioning.
The SCD80X560S is an 80 mm bore double-rod pneumatic cylinder that outputs an identical 2268 N of thrust in both directions at 0.5 MPa, thanks to its through-rod design where the 25 mm rod subtracts the same area from each piston face. With a 560 mm stroke and a built-in magnet for barrel-mounted sensors, it is a strong candidate for transfer shuttles and tooling that needs position feedback from either end of the cylinder.
This model uses a PT 3/8 port, an M20x1.5 rod thread on both ends, and an adjustable air cushion of 28 mm to decelerate the piston smoothly. The body length A(SCD) is 257 mm, making the retracted assembly longer than a comparable single-rod SC cylinder. The magnet band allows direct clamping of CMSG, DMSG, or EMSG sensors to detect piston position without external flags.

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/pull force at 0.5 MPa and through-rod design make this cylinder ideal for shuttling parts between two stations, where a tool can be mounted on each rod end for balanced, two-sided operation.
With the built-in -S magnet, CMSG or DMSG sensors clamp directly to the tie-rod barrel to confirm end-of-stroke at either end. The rear rod can also carry a separate sensor flag for a secondary control system.
The dual 25 mm rods provide inherent anti-rotation stability for a 560 mm stroke, allowing you to mount a wide pusher plate on the front rod without needing an external anti-rotate guide for light, centered loads.
Step up to the SCD100 bore if your application demands more than 2268 N per direction at 0.5 MPa; the 100 mm bore delivers 3681 N. If you only need force from one end, the single-rod SC80 is a simpler, more compact choice. For significant side loads on this 560 mm stroke, do not rely solely on the dual-rod guidance—add an external guide rail or switch to a guided cylinder to prevent rod bending and premature seal wear.
To replace an existing SCD80X560S, match the 80 mm bore, 560 mm stroke, PT port thread, basic mounting, and the -S magnet option. The mounting accessories for this SCD series are limited to FA front flange, LB foot mount, or TC centre trunnion with TCM1 bracket; flange FB and clevis CA/CB are not available.
Double-rod checklist
Because it is a double-rod cylinder, the push and pull forces are equal. At 0.5 MPa it delivers 2268 N, at 0.7 MPa it delivers 3175 N, and at the maximum operating pressure of 0.9 MPa it delivers 4082 N in both directions.
Choose the SCD80 when you need identical force and speed in both directions, or when you need a rear rod extension for mounting a second tool, a stopper, or a sensor cam. The through-rod also provides better bearing support than a single-rod cylinder, reducing rod deflection under light, centered loads.
