Airtac SDAD Double Rod Slim Cylinder SDAD50X50B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X50B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 50mm 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 SDAD50X50B
The AirTAC SDAD50X50B is a double-acting compact 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, giving you exactly 824.7 N of push and pull force at 0.5 MPa. This symmetry is vital when driving loads that must remain balanced in both strokes.
This specific SKU uses male M18x1.5 threads on the 20 mm rods at both ends, allowing you to securely mount tooling directly. The short body design drastically reduces axial mounting depth compared to standard round-body options. 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 SDAD50X50B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X50B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 50 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 SDAD50X50B Is Used
Symmetric Gripper Actuation
Drives an opposing parallel gripper where the 824.7 N equal push and pull force ensures balanced clamping pressure on both the extend and retract strokes.
Dual-End Transfer Mechanism
Uses the male M18x1.5 threads on both ends to push a part on one side while simultaneously triggering a mechanical dog on the opposite side.
Vertical Lift Fixture
Raises and lowers a 42 kg payload using the anti-rotation through-rod to prevent the platform from twisting during the 50 mm vertical transit.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X50B the Right Cylinder?
When sizing this unit, consider the neighbouring bores: the SDAD40 provides 527.8 N at 0.5 MPa, while the SDAD63 offers 1401.5 N at 0.5 MPa. The 50 mm bore hits a sweet spot, offering a safe working load of roughly 495 N (about 60 percent of the 0.5 MPa figure) and a vertical lift capacity of around 42 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and lets you mount a tool on one end and a dog on the other. Note that this SKU lacks the -S magnet, so magnetic position sensing is not possible without changing the model. Furthermore, a standard cylinder drifts when air is lost or the valve is centered; the bumper only decelerates near stroke end. For secure 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 SDAD50X50B FAQ
Because it is a double-rod cylinder, force is equal 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. The maximum operating pressure is 1.0 MPa.
No, this specific SKU does not have the -S option, meaning there is no piston magnet inside. To use AirTAC reed or electronic switches, you must select the -S variant of this model.
