Airtac SDAD Double Rod Slim Cylinder SDAD80X50
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X50 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 50mm 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 SDAD80X50
The AirTAC SDAD80X50 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 in each direction, delivering an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetry is highly advantageous when driving loads that require consistent kinetic energy regardless of travel direction.
The 80 mm bore uses a 25 mm piston rod and a PT3/8 port, yielding a theoretical maximum output of 463 kgf at 1.0 MPa. End-of-stroke deceleration is handled by a fixed NBR bumper rather than an adjustable air cushion. Note that this specific SKU lacks a piston magnet, so position sensing is not possible without switching to an -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X50 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X50 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 50 mm |
| Acting type | Double acting, rod both ends |
| Port size | PT3/8 |
| Rod end thread | M14×1.5 female / M22×1.5 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 (Ø80mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 2268 N |
| 0.7 MPa | 3175 N |
| Max (@1.0 MPa) | 463 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 SDAD80X50 Is Used
Web Guiding Mechanism
Utilizes the dual-end through-rod to mount a guiding roller on one side and a tracking flag on the other, ensuring the 2267.8 N bidirectional force keeps the web tension perfectly symmetric.
Balanced Lift Station
Lifts platens vertically where the equal push/pull geometry prevents sagging, safely hoisting a 115.6 kg load with a 2:1 margin during precise vertical transfer.
Dual-Side Clamping Jig
Drives opposing clamp jaws simultaneously from both rod ends, leveraging the anti-rotation properties to hold heavy workpieces without twisting under high pressure.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X50 the Right Cylinder?
When sizing this unit, compare its 2267.8 N @0.5 MPa capacity against adjacent bores: the SDAD63 provides 1401.5 N, while the SDAD100 offers 3524.9 N. For a 2:1 safety margin, the safe working load is approximately 1361 N, translating to a vertical lift capacity of roughly 115.6 kg. The through-rod geometry resists twisting and permits mounting a tool on one end with a dog on the opposite side.
This configuration features a 50 mm stroke, female M14x1.5 rod-end threads, and operates at 30-500 mm/s. Remember that a standard cylinder drifts when air is removed or the valve centers; the bumper only decelerates near the stroke end. For secure load holding without live pressure, integrate an external rod lock or a 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 SDAD80X50 FAQ
The double-rod design ensures force is equal in both directions. It outputs 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and has a theoretical maximum of 463 kgf at 1.0 MPa.
No, this specific SKU does not include a piston magnet. To use AirTAC reed or electronic switches, you must select the -S variant. The through-rod still allows dual-end mounting for mechanical dogs.
