Airtac SDAD Double Rod Slim Cylinder SDAD12X20B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X20B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm bore, 20mm stroke). The through-rod resists twisting and lets you drive a tool on one end while a switch or dog reads position on the other — with identical force in both directions.

About the Airtac SDAD Double Rod Slim Cylinder SDAD12X20B
The AirTAC SDAD12X20B is a compact double-acting cylinder featuring a 6 mm through-rod exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area is identical on extend and retract, yielding an equal push and pull force of 42.4 N at 0.5 MPa. This symmetry is ideal for driving balanced loads without twisting.
Designed for tight spaces, the short body minimizes axial footprint where larger profile cylinders fail to fit. This specific SKU features male M5x0.8 rod threads on both ends and uses an M5x0.8 air port. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD12X20B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X20B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 20 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 male (B) |
| 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 | Fixed NBR bumper (both ends) |
| Max standard stroke | Up to 50 mm |
Because a rod occupies both cylinder chambers, the effective area — and therefore the force — is identical in both directions. Specifications follow the official AirTAC SDAD datasheet.
Theoretical Output Force (Ø12mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 kgf |
Force uses the annular (rod-side) area on both strokes, so extend and retract match. Actual usable force is lower than theoretical due to friction. Size with a safety margin.

Where the Airtac SDAD Double Rod Slim Cylinder SDAD12X20B Is Used
PCB Panel Ejection
Pushes delicate circuit boards out of a test fixture with 42.4 N of symmetric force, preventing binding on the retract stroke.
Micro-Gripper Actuation
Drives a small gripping jaw on one rod end while the opposite end remains clear for a mechanical dog, utilizing the anti-twist through-rod.
Lab Sample Sorting
Transfers light vials between conveyor belts where the compact 12 mm body saves valuable axial space inside the sorting head.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X20B the Right Cylinder?
When sizing this 12 mm bore unit, consider the adjacent SDAD16 which raises the 0.5 MPa force to 86.4 N if your payload increases. Conversely, the 12 mm bore is the smallest available in this family. The through-rod geometry resists rotation and allows mounting a tool on one end while using the opposite end for a secondary action. A practical safe working load is roughly 25 N, allowing a vertical lift of about 2.2 kg with a 2:1 safety margin.
This configuration includes the B option for male M5x0.8 rod threads at both ends and lacks the S magnet, meaning it cannot support magnetic switches. Note that a standard cylinder drifts when air pressure is lost or a valve centers; the fixed NBR bumper only decelerates near stroke end and does not lock the load. For load holding, install an external rod lock or pilot-operated check valve.
Quick checklist
- ✓ Need equal force both directions?
- ✓ Anti-rotation / dual-end mounting?
- ✓ Space for a rod that exits both ends
- ✓ Port/thread type (PT)
- ✓ 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 Leave clearance for the rod exiting both ends.
- check Avoid side load on either rod end.
- check Front/rear covers are riveted — do not dismantle.
- check Installation by qualified personnel per AirTAC docs.
Airtac SDAD Double Rod Slim Cylinder SDAD12X20B FAQ
The push and pull forces are equal at 42.4 N at 0.5 MPa and 59.4 N at 0.7 MPa, with a theoretical maximum of 9 kgf at 1.0 MPa. The operating pressure range is 0.15 to 1.0 MPa.
Yes, the double-rod design allows you to attach a tool or fixture to the male M5x0.8 threads on both ends simultaneously. The through-rod also prevents the piston from rotating during movement.
