Airtac SDAD Double Rod Slim Cylinder SDAD12X15S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X15S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm bore, 15mm 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 SDAD12X15S
The AirTAC SDAD12X15S is a compact double-acting cylinder featuring a 6 mm piston rod exiting both ends of its riveted body. Because the rod occupies each chamber equally, the extend and retract forces are identical at 42.4 N for 0.5 MPa, providing true symmetric motion control without differential push or pull. This through-rod geometry also resists twisting during operation.
Designed for tight spaces, the short footprint saves axial mounting depth where larger profile cylinders cannot fit. The integrated -S piston magnet allows position detection using an AirTAC reed or electronic switch. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD12X15S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X15S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 15 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 SDAD12X15S Is Used
Micro-Grip Transfer
Uses the 42.4 N equal force to push and pull a small parts gripper without torque skew, ensuring precise placement in a 15 mm stroke.
Lab Sample Ejector
Mounts a test probe on one rod end and a switch dog on the opposite end, leveraging the anti-rotation through-rod for stable ejection.
Shuttle Divertor
Fits into shallow machine frames thanks to the compact riveted body, driving a lightweight sorting flap with symmetric force.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X15S the Right Cylinder?
When sizing this 12 mm bore model, consider the adjacent SDAD16, which raises the 0.5 MPa output to 86.4 N. If your application requires less force, this SDAD12X15S provides a safe working load of roughly 25 N, calculated as 60 percent of its 42.4 N capacity. For vertical lifts, expect to move about 2.2 kg safely while maintaining a 2 to 1 force margin.
The through-rod design allows you to mount a work tool on one end and a position dog on the opposite end simultaneously. Note that a plain cylinder does not hold its load if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or a pilot-operated check valve. This specific configuration includes the S magnet for sensing, a 15 mm stroke, an M5x0.8 port, and female M3x0.5 rod-end threads on both sides.
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 SDAD12X15S FAQ
The double-rod design provides equal force in both directions: 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.
Yes, the through-rod extends from both ends, allowing you to drive a tool on one side while mounting a position dog for a reed or electronic switch on the other, while also resisting rotation.
