Airtac SDAD Double Rod Slim Cylinder SDAD50X130
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X130 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 130mm 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 SDAD50X130
The AirTAC SDAD50X130 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 on extend and retract, delivering an equal push and pull force of 824.7 N at 0.5 MPa. This symmetry is essential when driving loads that require consistent dynamics in both travel directions.
With a 50 mm bore and 130 mm stroke, this unit uses a PT1/4 port and a 20 mm piston rod at each end. The short body design minimizes axial mounting depth compared to conventional round-body options. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. Note that this specific SKU lacks a piston magnet and therefore cannot support reed or electronic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD50X130 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X130 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 130 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 SDAD50X130 Is Used
Symmetric Transfer
Drives a 42 kg vertical lift fixture with equal 824.7 N push and pull forces, ensuring smooth bidirectional part transfer without twisting.
Dual-End Tooling
Mounts a forming tool on the front rod while the rear rod extension links to a mechanical stop, leveraging the anti-rotation through-rod for precise 130 mm strokes.
Balanced Lift Station
Raises and lowers a 495 N payload using the equal annular area, maintaining consistent speed and force throughout the 130 mm travel in a compact footprint.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X130 the Right Cylinder?
When sizing this model, compare its 824.7 N output at 0.5 MPa against adjacent bores: the SDAD40 provides 527.8 N, while the SDAD63 offers 1401.5 N. Based on the 824.7 N figure, the safe working load is approximately 495 N (60 percent capacity), translating to a vertical lift capability of about 42 kg with a 2:1 safety margin.
The through-rod geometry resists twisting and permits mounting a tool on one end while using the opposite end for a secondary mechanism. Remember that a standard cylinder drifts when air pressure is lost or the valve is centered; the fixed bumper only decelerates near the stroke end and will not hold the load. For secure positioning, integrate an external rod lock or pilot-operated check valve. Confirm your bore, 130 mm stroke, PT1/4 port, female M10x1.5 rod threads, and lack of magnet for this configuration.
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 SDAD50X130 FAQ
The SDAD50X130 delivers an equal force of 824.7 N at 0.5 MPa and 1154.5 N at 0.7 MPa in both push and pull directions, with a theoretical maximum of 168 kgf at 1.0 MPa. Because the 130 mm stroke exceeds the 120 mm standard maximum for this bore, it is classified as a nonstandard stroke.
This specific SKU does not include a piston magnet, so it cannot support reed or electronic switches; you would need the -S variant for sensing. Additionally, the cylinder will drift on air loss or valve centering, so for load holding you must install an external rod lock or pilot-operated check valve.
