Airtac SDAD Double Rod Slim Cylinder SDAD80X55
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X55 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 55mm 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 SDAD80X55
The AirTAC SDAD80X55 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, yielding equal push and pull forces of 2267.8 N at 0.5 MPa. This symmetry is highly advantageous for moving balanced loads without shifting the center of mass.
Designed for tight footprints, the short body saves axial mounting depth where larger profile cylinders cannot fit. The 25 mm rod resists twisting under offset loads, while the PT3/8 port handles high flow. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, keeping the overall length minimal.
Airtac SDAD Double Rod Slim Cylinder SDAD80X55 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X55 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 55 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 SDAD80X55 Is Used
Elevator Stage Lifting
Raises and lowers a 110 kg platen vertically. The symmetric through-rod ensures identical force whether pushing the stage up or pulling it down, preventing jerky transitions.
Precision Guiding Jig
Drives a dual-end guiding pin into a machining fixture. The 25 mm rod resists torsional deflection, maintaining alignment under lateral stress during clamping.
Reciprocating Transfer Unit
Shuttles a heavy workpiece carrier between two stations. Mounting a dog on the opposite rod end provides a mechanical stop reference without interfering with the primary tool.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X55 the Right Cylinder?
When sizing this 80 mm bore, evaluate both neighbors: the SDAD63 delivers 1401.5 N at 0.5 MPa, while the SDAD100 provides 3524.9 N. The SDAD80X55 strikes a balance, offering a safe working load around 1361 N (60% of its 0.5 MPa rating) and a vertical lift capacity of roughly 115.6 kg with a 2:1 safety margin. This specific SKU lacks the -S magnet, so position sensing is unavailable unless you select the -S variant for AirTAC reed or electronic switches.
Confirm the 55 mm stroke falls within the 130 mm standard limit for this bore. The female M14x1.5 rod-end threads accommodate standard mounts on both ends. Note that this cylinder does not hold position on air loss; the piston drifts when pressure is removed or the valve centers. For load holding without live pressure, integrate an external rod lock or 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 SDAD80X55 FAQ
Because the rod exits both ends, push and pull forces are identical: 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 geometry allows driving a tool on one end while using the opposite end for external mechanical referencing. However, this specific SKU lacks the -S magnet, so it cannot accept magnetic switches directly.
