Airtac SDAD Double Rod Slim Cylinder SDAD12X20
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X20 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 SDAD12X20
The AirTAC SDAD12X20 is a double-acting compact cylinder featuring a 12mm bore and 20mm stroke. Its defining trait is the through-rod design that exits both ends of the riveted body, ensuring the annular area remains identical on extend and retract. Consequently, push and pull forces match exactly at 42.4 N each way when operating at 0.5 MPa.
This thin footprint saves valuable axial mounting depth where larger profile bodies cannot fit. The integrated fixed NBR bumper decelerates the piston near stroke ends without requiring adjustment. Operating speeds span 30-500 mm/s, yielding a safe working load of roughly 25 N for reliable motion control.
Airtac SDAD Double Rod Slim Cylinder SDAD12X20 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X20 |
|---|---|
| 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 SDAD12X20 Is Used
Micro-Gripper Actuation
Drives small gripper jaws with equal 42.4 N force in both directions, ensuring delicate components are clamped and released smoothly without rotational twist.
Dual-End Probe Mounting
Uses the through-rod exiting both ends to advance a testing probe on the front while a mechanical dog triggers a hard stop on the rear within a 20mm travel.
Lab Sample Shuttling
Moves light analytical trays rapidly across a 20mm gap, capitalizing on the compact riveted body to fit inside tight laboratory automation enclosures.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X20 the Right Cylinder?
When sizing this unit, compare its 42.4 N output at 0.5 MPa against the adjacent SDAD16, which delivers 86.4 N. If your application requires less than 25 N of safe working load, the 12mm bore is optimal, whereas heavier loads necessitate stepping up to the 16mm variant. This specific SKU lacks the S suffix, meaning it has no piston magnet and cannot accept reed or electronic switches.
The through-rod geometry resists twisting and permits driving a tool on one end while mounting a secondary fixture on the opposite side. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the fixed bumper only decelerates impact and does not lock the load. For vertical lifting up to 2.2 kg with a 2:1 safety margin, this model provides stable, symmetric actuation.
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 SDAD12X20 FAQ
Because the rod occupies both chambers, extend and retract forces are identical: 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a theoretical maximum of 9 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not include the S option, so it lacks a piston magnet and cannot trigger reed or electronic switches. You would need the SDAD12X20S variant to utilize the body sensor grooves for position feedback.
