Airtac SCD Standard Cylinder SCD160X80S
The AirTAC Airtac SCD Standard Cylinder SCD160X80S 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.

About the Airtac SCD Standard Cylinder SCD160X80S
The AirTAC SCD160X80S is a double-acting, double-rod pneumatic cylinder delivering identical push and pull thrust in both directions. At 0.5 MPa, it produces a balanced 9425 N of force, rising to 16964 N at the maximum operating pressure of 0.9 MPa, thanks to its 40 mm through-rod that subtracts the same area from each chamber.
This 160 mm bore model features a body length of 352 mm and a 29 mm adjustable air cushion at each end for smooth deceleration. The built-in magnet allows direct mounting of CMSG, DMSG, or EMSG sensors on the tie-rod barrel, providing clean, contactless end-of-stroke detection without external brackets.
Airtac SCD Standard Cylinder SCD160X80S Technical Specifications
| Model | Airtac SCD Standard Cylinder SCD160X80S |
|---|---|
| Series | SCD double-rod tie-rod cylinder (ISO 6430 class) |
| Bore size | Ø160 mm |
| Rod diameter | Ø40 mm (both ends) |
| Stroke | 80 mm |
| Rod configuration | Double rod — rod through both caps |
| Acting type | Double acting |
| Port size | PT3/4 |
| Rod thread | M36×2 |
| 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 – 500 mm/s |
| Cushion | Adjustable, 29 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 (Ø160mm, double rod)
| 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.

Where the Airtac SCD Standard Cylinder SCD160X80S Is Used
Bi-Directional Clamping
Provides equal clamping force from both ends of the cylinder, ideal for fixtures that secure a part against a central stop or require symmetric pressure application.
Heavy Transfer Shuttle
Moves a heavy pallet or tooling plate between two stations with identical speed and thrust in each direction, simplifying flow control and cycle time calculations.
Rear-Mounted Sensing
The protruding rear rod with the -S magnet carries a sensor flag or cam, allowing position feedback to be taken from the protected back side of the machine.
Is the Airtac SCD Standard Cylinder SCD160X80S the Right Cylinder?
Choose the SCD160 bore when your application requires roughly 9425 N of force in both directions at standard plant pressure. If you can work with a lower force, stepping down to the SCD125 bore saves space and weight, offering 5734 N at the same 0.5 MPa. For purely single-sided tooling, a single-rod SC160 cylinder would provide a higher push force on the full-bore side, making it a more efficient choice if the pull stroke is not load-bearing.
For a direct replacement, match the 160 mm bore, 80 mm stroke, PT port thread, and the SCD double-rod configuration. This S-suffix model includes the magnet for sensor compatibility. If your existing cylinder uses a different mounting style, AirTAC's LB, FA, or TC accessories can be bolted on to match the original footprint.
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 SCD160X80S FAQ
Because it is a double-rod cylinder, the push and pull forces are identical. The force is 9425 N at 0.5 MPa, 13194 N at 0.7 MPa, and reaches 16964 N at the maximum operating pressure of 0.9 MPa.
Select the SCD when you need perfectly symmetric speed and force for both directions, or when you require a rear rod extension to mount tooling, a mechanical stop, or a sensor target. A single-rod SC cylinder provides a higher push force on the full-bore side, so it is more efficient if only one direction bears the main load.
