Airtac SCD Standard Cylinder SCD80X160S
The AirTAC Airtac SCD Standard Cylinder SCD80X160S 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, 160mm stroke, PT3/8 ports and adjustable end cushioning.

About the Airtac SCD Standard Cylinder SCD80X160S
The SCD80X160S is an 80 mm bore, 160 mm stroke double-rod pneumatic cylinder that produces an identical 2268 N of force in both directions at 0.5 MPa, thanks to its through-rod design where the 25 mm rod occupies both pressure areas equally. This symmetry makes it ideal for applications needing balanced, repeatable motion for tooling on both ends, such as a rear-mounted sensor flag or a dual-sided clamp.
The built-in magnet (denoted by the 'S' suffix) allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel for non-contact position sensing, simplifying stroke-end confirmation without external brackets. With a 28 mm adjustable air cushion at each end, it decelerates the 160 mm stroke smoothly, while the PT3/8 ports and M20x1.5 rod threads offer standard connectivity.
Airtac SCD Standard Cylinder SCD80X160S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD80X160S |
|---|---|
| Series | SCD double-rod tie-rod cylinder |
| Bore size | Ø80 mm |
| Rod diameter | Ø25 mm (both ends) |
| Stroke | 160 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT3/8 |
| Rod thread | M20×1.5 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |
| Cushion | Adjustable, 28 mm |
| Max stroke | Up to 1500 mm |
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.
Theoretical Output Force (Ø80mm, double rod)
| 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.

Where the Airtac SCD Standard Cylinder SCD80X160S Is Used
Two-Sided Transfer Shuttle
The equal push/pull force of 2268 N at 0.5 MPa makes this cylinder perfect for a shuttle table where a fixture is mounted on each rod end, moving parts between two stations with identical speed and power in both directions.
Sensor-Controlled Stopper Gate
With the built-in magnet, a CMSG sensor can be clamped directly to the barrel to confirm the gate's position at either end of the 160 mm stroke, providing a clean signal for a part-stopping application without needing external flags.
Dual-End Alignment Tool
The 25 mm through-rod provides better bearing support than a single-rod cylinder, making it suitable for a light-duty pressing or alignment tool where a die set is attached to both the front and rear rod extensions for guided, symmetric motion.
Is the Airtac SCD Standard Cylinder SCD80X160S the Right Cylinder?
For a step up in force, the SCD100 bore delivers 3681 N at the same 0.5 MPa, while stepping down to the SCD63 provides 1402 N. If your application only requires force from one side, a single-rod SC80 cylinder would be a lighter and more compact choice. The double-rod design offers superior guidance and anti-rotation compared to a single rod, but for significant side loads, a guided cylinder is still required to protect the rod bearings. As a direct replacement, match the 80 mm bore, 160 mm stroke, PT port thread, basic mounting, and the integrated magnet feature.
Double-rod checklist
- ✓ Need equal force / speed both directions?
- ✓ Rear rod for tooling, stopper or sensor flag?
- ✓ Better rod guidance / anti-rotation?
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Keep BOTH rod ends clear of side load and interference.
- check Adjust end cushion screws for smooth stops.
- check Use SCD mounting accessory (FA / LB / TC / TCM1).
- check Installation by qualified personnel per AirTAC docs.
Airtac SCD Standard Cylinder SCD80X160S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. At 0.5 MPa it produces 2268 N, at 0.7 MPa it's 3175 N, and at the maximum operating pressure of 0.9 MPa, the force is 4082 N in both directions.
Choose an SCD when you need identical force and speed in both directions, or when you need to mount tooling, a stop, or a sensor target on the rear rod. The through-rod also provides better guidance and anti-rotation than a single-rod cylinder, though it is not a replacement for a fully guided unit under heavy side loads.
