Airtac SDAD Double Rod Slim Cylinder SDAD50X65B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X65B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 65mm 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 SDAD50X65B
The AirTAC SDAD50X65B is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies each chamber equally, the annular area matches on extend and retract, delivering an identical 824.7 N of push and pull force at 0.5 MPa. This symmetry is essential when driving loads that must remain balanced in both directions.
Equipped with male M18x1.5 threads on the 20 mm rods at both ends, this unit allows you to mount tooling on one side while using the opposite end for a dog or secondary mechanism. The short body design minimizes axial footprint, and a fixed NBR bumper decelerates the piston at stroke extremes. Note this specific SKU lacks a piston magnet, so position sensing is not supported.
Airtac SDAD Double Rod Slim Cylinder SDAD50X65B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X65B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 65 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 SDAD50X65B Is Used
Symmetric Gripper Actuation
Drives opposing gripper jaws with equal 824.7 N force in both directions, ensuring centered clamping on delicate extrusions without rotational deflection.
Dual-End Lift Station
Lifts up to 42 kg vertically using one rod end, while the opposite male M18x1.5 end simultaneously triggers a mechanical dog for stroke confirmation.
Transfer Push-Pull Unit
Alternates push and pull cycles on a conveyor line, leveraging the matched annular force to accelerate and decelerate payloads consistently.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X65B the Right Cylinder?
When sizing this 50 mm bore actuator, consider the SDAD40 which yields 527.8 N at 0.5 MPa, or step up to the SDAD63 providing 1401.5 N at 0.5 MPa. The SDAD50X65B offers a safe working load of roughly 495 N, which translates to a vertical lift capacity of about 42 kg when applying a 2:1 safety margin. Operating pressure spans 0.15 to 1.0 MPa, with a speed range of 30-500 mm/s.
The through-rod geometry inherently resists twisting, making it superior for applications demanding high anti-rotation stability. Keep in mind that a standard cylinder cannot hold a load if air pressure drops or the valve centers; the piston will drift. For secure load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This configuration includes PT1/4 ports and male M18x1.5 rod threads on both ends.
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 SDAD50X65B FAQ
The push and pull forces are identical because the rod exits both ends. It generates 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa, with 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 a piston magnet, so it cannot accept reed or electronic switches. You would need the -S variant for sensing. However, the male M18x1.5 rod protruding from the rear allows you to mount a physical dog to trigger an external sensor.
