Airtac SDAD Double Rod Slim Cylinder SDAD80X30
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X30 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 30mm 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 SDAD80X30
The AirTAC SDAD80X30 is a compact double-acting cylinder featuring a 25 mm piston rod exiting both ends of its riveted body. Because a rod occupies each chamber, the annular areas match, delivering an identical push and pull force of 2267.8 N at 0.5 MPa. This symmetry prevents twisting during traversal and allows you to drive a tool on one end while mounting a dog on the opposite side.
Operating via a PT3/8 port, this unit travels a 30 mm stroke at speeds between 30 and 500 mm/s. End shock is managed strictly by a fixed NBR bumper that decelerates the piston near stroke limits. The short body design drastically reduces axial mounting depth compared to conventional round-body units, fitting into tight machine frames.
Airtac SDAD Double Rod Slim Cylinder SDAD80X30 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X30 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 30 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 SDAD80X30 Is Used
Symmetric Lift Stations
Lifts 115.6 kg vertically with a 2:1 safety margin using its equal 2267.8 N bidirectional force, preventing sag on the return stroke.
Anti-Rotation Guiding
Drives a precision straightener jig while the opposing rod end mounts a mechanical dog, leveraging the through-rod to resist twist.
Compact Press Assembly
Fits into shallow press frames thanks to the short riveted body, applying 3175 N at 0.7 MPa for seating bearings without requiring deep axial clearance.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X30 the Right Cylinder?
When sizing this 80 mm bore, stepping down to the SDAD63 yields 1401.5 N at 0.5 MPa, while stepping up to the SDAD100 provides 3524.9 N. This SDAD80X30 strikes a middle ground with 2267.8 N at 0.5 MPa, offering a safe working load of roughly 1361 N for a 2:1 margin, or a vertical lift capacity of about 115.6 kg. The through-rod geometry ensures high torsional resistance for guided lifts.
This specific SKU lacks a piston magnet, meaning it cannot support reed or electronic switches; choose the -S variant if position sensing is required. The female M14x1.5 rod-end threads accommodate standard mounts. Remember that a plain cylinder drifts when air is lost or the valve centers—the fixed bumper only decelerates near stroke end, so add 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 SDAD80X30 FAQ
The double-rod design provides equal force in both directions: 2267.8 N at 0.5 MPa, 3175 N at 0.7 MPa, and a theoretical maximum of 463 kgf at 1.0 MPa.
Yes, the through-rod resists rotation and allows dual-end mounting. However, this specific SKU has no magnet; you must select the -S option to use reed or electronic switches for position feedback.
