Airtac SDAD Double Rod Slim Cylinder SDAD50X130B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X130B 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 SDAD50X130B
The AirTAC SDAD50X130B 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, giving you 824.7 N of push and pull force at 0.5 MPa. This symmetric output is perfect for balanced tooling.
This specific SKU uses male M18x1.5 threads on both 20 mm rod ends, allowing direct mounting of heavy fixtures. The short body design saves axial depth compared to standard round-body cylinders. It relies on a fixed NBR bumper at each end to absorb end-of-stroke shock rather than an adjustable cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD50X130B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X130B |
|---|---|
| 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 SDAD50X130B Is Used
Gripper Synchronization
Drives opposing grippers on both male M18x1.5 rod ends simultaneously, ensuring perfectly parallel clamping using the equal 824.7 N bidirectional force.
Balanced Lift Stage
Lifts a 42 kg vertical payload using the through-rod to prevent platform twist during elevation, maintaining stability without needing external guides.
Dual-Action Transfer
Pushes a part on the forward stroke while pulling a return fixture on the reverse, capitalizing on the identical extend and retract forces.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X130B the Right Cylinder?
When sizing this 50 mm bore, the smaller SDAD40 provides 527.8 N at 0.5 MPa, while the larger SDAD63 yields 1401.5 N at 0.5 MPa. This model sits in the middle, offering a safe working load of roughly 495 N or a vertical lift of about 42 kg with a 2:1 margin. The through-rod geometry prevents twisting and lets you drive a tool on one end while mounting a dog on the opposite side.
This configuration has a 130 mm stroke, which exceeds the 120 mm standard maximum, making it a nonstandard stroke. It features a PT1/4 port and male M18x1.5 rod threads. Because this SKU lacks the -S magnet, it cannot accept magnetic switches. Note that a plain cylinder drifts when air is lost; use an external rod lock or pilot-operated check valve for load holding.
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 SDAD50X130B FAQ
The push and pull forces are equal 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 include a piston magnet, so it cannot accept reed or electronic switches. You would need the -S variant for internal sensing. However, the dual male M18x1.5 rod ends allow you to mount an external dog or target on the opposite side for external sensing.
