Airtac SDAD Double Rod Slim Cylinder SDAD50X80
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD50X80 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø50mm bore, 80mm 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 SDAD50X80
The AirTAC SDAD50X80 is a double-acting, double-rod compact cylinder featuring a 50mm bore and an 80mm stroke. Because the piston rod exits both ends of the riveted body, the annular area remains identical in each chamber. This geometry ensures push force equals pull force, delivering exactly 824.7 N at 0.5 MPa in both directions. The short body design drastically reduces axial mounting depth compared to conventional round-body units.
A 20mm diameter through-rod resists twisting during operation, allowing you to drive a tool on one end while mounting a dog or fixture on the opposite side. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so it cannot host reed or electronic switches without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD50X80 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD50X80 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø50 mm |
| Stroke | 80 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 SDAD50X80 Is Used
Symmetric Transfer Gripper
Drives a dual-sided gripper where the equal 824.7 N extend and retract forces prevent twisting during heavy component transfers.
Balanced Lift Station
Elevates a 42 kg platen vertically using the through-rod design to maintain stable alignment without rotational drift.
Dual-End Sealing Jig
Mounts a sealing head on one rod end and a mechanical dog on the opposite end within a compact packaging machine frame.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD50X80 the Right Cylinder?
When sizing this model, compare its 824.7 N output at 0.5 MPa against adjacent bores. Stepping down to the SDAD40 yields 527.8 N, while stepping up to the SDAD63 provides 1401.5 N. For your application, the 50mm bore offers a computed safe working load of roughly 495 N, or a vertical lift capacity of about 42 kg with a 2:1 safety margin. Confirm your requirements for the PT1/4 port, female M10x1.5 rod-end threads on both ends, and the 80mm stroke.
The through-rod design provides excellent anti-rotation stability for symmetric loads. Keep in mind that a standard cylinder does not hold position 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 a pilot-operated check valve. Operating speed ranges from 30-500 mm/s.
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 SDAD50X80 FAQ
The push and pull forces are identical because of the double-rod design. 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 in both directions. The maximum operating pressure is 1.0 MPa.
This specific SKU does not include a piston magnet, so it cannot support reed or electronic switches. You would need the SDAD50X80S variant to enable sensing. However, the through-rod still allows you to mount a mechanical dog or external sensor on the opposite rod end.
