Airtac SDAD Double Rod Slim Cylinder SDAD50X5S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X5S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 5mm 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 SDAD50X5S
The AirTAC SDAD50X5S is a compact double-acting cylinder featuring a 50mm bore and a 5mm stroke. Because the piston rod exits both ends, the annular area remains identical in both chambers, ensuring push force equals pull force at 824.7 N each way under 0.5 MPa. This symmetric thrust is ideal for balanced actuation tasks.
The short riveted body saves axial mounting depth where standard profile cylinders cannot fit. A built-in magnet (-S) enables position detection via AirTAC reed or electronic switches. End-of-stroke energy is managed by a fixed NBR bumper, which decelerates the piston rather than acting as an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X5S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X5S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 5 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 SDAD50X5S Is Used
Short-Stroke Clamping
Provides 824.7 N of equal push and pull force for securing heavy workpieces during machining operations.
Symmetric Ejection
The dual-end through-rod drives a part ejector on one side while a position dog triggers a sensor on the opposite end.
Anti-Rotation Transfer
Resists twisting during lateral part transfer, ensuring the 5mm stroke completes without angular deflection.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X5S the Right Cylinder?
When sizing this drive, the SDAD40X5S provides 527.8 N at 0.5 MPa, while stepping up to the SDAD63X5S yields 1401.5 N. The 50mm bore hits a middle ground, offering a safe working load of roughly 495 N (about 60 percent of its 0.5 MPa rating) and a vertical lift capacity near 42 kg with a 2:1 safety margin. The through-rod design resists twisting and allows mounting a tool on one end and a dog on the opposite side.
This configuration includes the -S magnet for reed or electronic sensing and female M10x1.5 rod-end threads on both sides. Air connects via PT1/4 ports. Note that a plain cylinder drifts when air is lost or the valve centers; the fixed bumper only decelerates near stroke end. For load holding without live pressure, 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 SDAD50X5S FAQ
The double-rod design provides equal force in both directions: 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa. The theoretical maximum is 168 kgf at 1.0 MPa.
The through-rod prevents rotation and allows mounting tooling on both ends simultaneously. The built-in magnet works with AirTAC reed or electronic switches for precise end-of-stroke position feedback.
