Airtac SDAD Double Rod Slim Cylinder SDAD50X10B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X10B 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 SDAD50X10B
The AirTAC SDAD50X10B is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, delivering an equal push and pull force of 824.7 N at 0.5 MPa. This symmetric output is ideal for driving loads that require consistent force on extension and retraction.
This specific configuration includes male M18x1.5 threads on both rod ends, allowing direct mounting of tooling on either side. The 50 mm bore uses a PT1/4 port and a 20 mm rod. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note this SKU lacks a piston magnet, so position sensing is not supported without the -S option.
Airtac SDAD Double Rod Slim Cylinder SDAD50X10B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X10B |
|---|---|
| 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 SDAD50X10B Is Used
Edge Guide Mechanism
Uses the 824.7 N equal force to push and pull a web guide symmetrically, maintaining tension without skewing the material.
Dual-End Transfer Arm
Mounts a grip on one male M18x1.5 rod end and a dog on the opposite end to trip a mechanical limit, saving axial space.
Vertical Lift Platform
Lifts a 42 kg payload vertically with a 2:1 safety margin, relying on the through-rod to resist torsional load.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X10B the Right Cylinder?
When sizing this model, compare its 824.7 N @0.5 MPa capacity against adjacent bores: the SDAD40 provides 527.8 N, while the SDAD63 offers 1401.5 N. For this 50 mm bore, a safe working load is approximately 495 N (about 60% of the 0.5 MPa figure), yielding a vertical lift capacity of roughly 42 kg with a 2:1 safety margin. Choose the 50 mm bore when the smaller 40 mm lacks thrust or the 63 mm is physically too large.
The through-rod geometry prevents twisting and permits mounting a work tool on one end while using the opposite end for a mechanical dog. Remember that a plain SDAD does not hold position on air loss or valve centering—the piston will drift, as the fixed NBR bumper only decelerates near the stroke end. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This SDAD50X10B variant features male M18x1.5 rod threads, a 10 mm stroke, PT1/4 port, and no magnet.
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 SDAD50X10B 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.
Yes, the through-rod exits both ends with male M18x1.5 threads, allowing you to drive a tool on one side while attaching a dog or secondary mechanism on the other, which also prevents rod rotation.
