Airtac SDAD Double Rod Slim Cylinder SDAD80X40
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X40 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 40mm 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 SDAD80X40
The AirTAC SDAD80X40 is a double-acting compact cylinder featuring a 25 mm piston rod exiting both ends of its riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding equal push and pull force of 2267.8 N at 0.5 MPa. This symmetry is essential when driving rigid loads that must not twist during reversal.
The through-rod geometry inherently resists rotation, letting you mount a work tool on one end and a dog or limit switch on the opposite side. A short riveted body saves axial mounting depth compared to standard round-body units. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion. This SKU lacks a piston magnet, so it cannot host magnetic switches without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X40 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X40 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 40 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 SDAD80X40 Is Used
Symmetric Lift Station
Drives a vertical lift platform requiring identical 2267.8 N force on both up and down strokes to prevent binding in the guide rails.
Dual-End Tooling Chuck
Mounts a machining fixture on the front rod while the rear protrusion operates a mechanical dog, leveraging the 25 mm through-rod for anti-rotation.
Inline Transfer Gate
Diverts heavy pallets along a conveyor belt, using the compact riveted body to fit within tight 80 mm lateral clearance frames.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X40 the Right Cylinder?
When sizing this 80 mm bore, compare it directly with its neighbours. Dropping down to the SDAD63 reduces output to 1401.5 N at 0.5 MPa, whereas stepping up to the SDAD100 increases thrust to 3524.9 N at 0.5 MPa. The SDAD80X40 strikes a middle ground, 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.
The 25 mm rod uses an M14x1.5 female thread at both ends and a PT3/8 port. Remember that a plain double-rod cylinder drifts if air pressure is lost or the valve centres; the fixed bumper only decelerates near stroke end and provides no load holding. For suspended loads, install 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 SDAD80X40 FAQ
The SDAD80X40 generates 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa, with a theoretical maximum of 463 kgf at 1.0 MPa. Because it is a double-rod cylinder, these force figures are exactly equal in both the extend and retract directions.
No, this specific SKU does not include a piston magnet, so it cannot trigger reed or electronic switches. You must select the SDAD80X40S variant to enable sensing, or mount an external mechanical dog on the exposed rear rod to trip a limit switch.
