Airtac SDAD Double Rod Slim Cylinder SDAD50X15S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X15S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 15mm 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 SDAD50X15S
The AirTAC SDAD50X15S is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the piston rod occupies each chamber equally, the annular area is identical on extend and retract, delivering 824.7 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balanced tooling tasks.
The integrated -S piston magnet enables position detection using AirTAC reed or electronic switches fitted directly into the body grooves. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock without requiring adjustment. The short 15 mm stroke and space-saving body geometry provide a minimal mounting footprint for tight assemblies.
Airtac SDAD Double Rod Slim Cylinder SDAD50X15S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X15S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 15 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 SDAD50X15S Is Used
Symmetric Gripper Actuation
Drives an opposing jaw mechanism where the equal 824.7 N extend and retract forces ensure balanced clamping pressure on delicate components without twisting.
Short-Stroke Lifting Station
Raises a 42 kg payload vertically through 15 mm; the dual-end rod allows a dog to trip an electronic switch on the back side for precise height confirmation.
Pin Insertion Tooling
Mounts a press head on the front rod while the rear extension stabilizes the assembly, utilizing the fixed NBR bumper to absorb the 1154.5 N impact at 0.7 MPa.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X15S the Right Cylinder?
When sizing this 50 mm bore model, consider the neighbouring bores: the SDAD40 provides 527.8 N at 0.5 MPa, while the SDAD63 yields 1401.5 N at 0.5 MPa. The SDAD50X15S sits perfectly between them, offering a safe working load of roughly 495 N (about 60 percent of its 824.7 N capacity) and a vertical lift capability of approximately 42 kg with a 2:1 safety margin.
The through-rod design resists twisting and permits mounting a work tool on one end while a dog triggers a switch on the opposite end. Remember that a standard cylinder drifts when air pressure is lost or the valve is centred; the fixed NBR bumper only decelerates the stroke end and does not lock the load. For secure load holding, install an external rod lock or pilot-operated check valve. This configuration includes a PT1/4 port, a 20 mm rod diameter, female M10x1.5 rod-end threads on both sides, and the built-in 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 SDAD50X15S FAQ
The push and pull forces are equal because the rod exits both ends. It generates 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.
Yes. The through-rod design resists rotation and allows you to drive a tool on one end while mounting a dog on the opposite end. The built-in -S magnet works with AirTAC reed or electronic switches for position detection.
