Airtac SDAD Double Rod Slim Cylinder SDAD50X10S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X10S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 10mm 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 SDAD50X10S
The AirTAC SDAD50X10S is a compact double-acting cylinder featuring a piston rod exiting both ends of its riveted body. Because a rod occupies each chamber, the annular area is identical on extend and retract, yielding exactly 824.7 N of force at 0.5 MPa in both directions. This symmetry is ideal for balanced gripping or lifting tasks.
The built-in -S piston magnet supports AirTAC reed or electronic switches for end-position sensing. A fixed NBR bumper decelerates the short 10 mm stroke at the ends, while the 20 mm through-rod resists twisting and allows mounting a dog on the opposite end.
Airtac SDAD Double Rod Slim Cylinder SDAD50X10S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X10S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 10 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT1/4 |
| Rod end thread | M10×1.5 female / M18×1.5 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 120 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 (Ø50mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 825 N |
| 0.7 MPa | 1155 N |
| Max (@1.0 MPa) | 168 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 SDAD50X10S Is Used
Symmetric Gripper Actuation
Drives an opposing jaw mechanism where the 824.7 N equal push and pull force ensures balanced clamping pressure on precision metal parts.
Dual-End Diverting
Uses the through-rod geometry to push a diverting flap on one side while mounting a magnetic dog on the opposite end to trigger a reed switch.
Short-Stroke Lifting
Raises a 42 kg workpiece vertically over a 10 mm gap, relying on the anti-rotation properties of the double rod to prevent load twisting.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X10S the Right Cylinder?
This 50 mm bore generates 824.7 N each way at 0.5 MPa, sitting between the smaller SDAD40 at 527.8 N and the larger SDAD63 at 1401.5 N. The computed safe working load is roughly 495 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift capacity of approximately 42 kg with a 2:1 safety margin.
The through-rod provides excellent anti-rotation stability and dual-end mounting flexibility. Note that a plain cylinder drifts when air is lost or the valve is centered; use an external rod lock or pilot-operated check valve for load holding. This configuration includes the S magnet, female M10x1.5 rod threads, and a PT1/4 port.
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 SDAD50X10S FAQ
The double-rod design provides equal force in both directions: 824.7 N at 0.5 MPa, 1154.5 N at 0.7 MPa, and a theoretical maximum of 168 kgf at 1.0 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke end; you must add an external rod lock or pilot-operated check valve for load holding.
