Airtac SDAD Double Rod Slim Cylinder SDAD80X120B
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X120B is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 120mm 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 SDAD80X120B
The AirTAC SDAD80X120B 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, giving exactly 2267.8 N of force at 0.5 MPa on both extend and retract strokes. This symmetry prevents twisting and ensures stable motion for heavy guided payloads.
Equipped with male M22x1.5 threads on both rod ends, this unit drives tooling from either side while saving axial mounting depth. The bore uses a PT3/8 port and runs at 30-500 mm/s. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion, handling impact within the compact footprint.
Airtac SDAD Double Rod Slim Cylinder SDAD80X120B Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X120B |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 120 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 SDAD80X120B Is Used
Symmetric Lifting Jig
Drives a lift platform with equal push and pull forces of 2267.8 N at 0.5 MPa, preventing payload twist during vertical transit.
Dual-End Machining Fixture
Uses the male M22x1.5 rods on both ends to mount a clamp on one side and a mechanical dog on the opposite side for external tracking.
Heavy Transfer Diverter
Handles large product routing with a robust 25 mm rod diameter, relying on the fixed NBR bumper to absorb end-of-stroke shock.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X120B 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 at 0.5 MPa. This model provides a safe working load of roughly 1361 N, allowing a vertical lift of about 115.6 kg with a 2:1 safety margin. The dual-end male M22x1.5 rods allow mounting a dog on the opposite end from the tool.
Remember that a plain SDAD does not hold position if air pressure drops or the valve centers; the piston will drift. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This specific SKU lacks the -S magnet, so it cannot accept magnetic switches.
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 SDAD80X120B FAQ
The double-rod design provides equal force in both directions: 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum is 463 kgf at 1.0 MPa.
No, this specific SKU does not include the -S piston magnet, so it cannot accept reed or electronic switches. You can use the dual-end male M22x1.5 rods to mount external mechanical dogs for position sensing.
