Airtac SDAD Double Rod Slim Cylinder SDAD80X120
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X120 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 SDAD80X120
The AirTAC SDAD80X120 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 on extend and retract, yielding equal push and pull force of 2267.8 N at 0.5 MPa. This symmetry is essential for applications requiring consistent kinetic output regardless of travel direction.
Equipped with a 25 mm piston rod and PT3/8 air port, this unit provides a substantial 120 mm stroke while maintaining a short axial footprint. The fixed NBR bumper at each end decelerates the piston near stroke termination. Without a piston magnet, this specific SKU cannot host reed or electronic switches; position sensing requires the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X120 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X120 |
|---|---|
| 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 SDAD80X120 Is Used
Web Guiding Mechanism
Utilizes the dual-end rod to mount a guiding roller on one side and a tension flag on the other, relying on the 2267.8 N equal force to prevent twisting during material tracking.
Symmetric Lift Station
Drives a vertical lifting platform where identical extend and retract kinetics are critical for safely elevating an 115.6 kg payload with a 2:1 safety margin.
Riveting Press Base
Employs the anti-rotation geometry of the through-rod to maintain precise perpendicular alignment during repetitive riveting, absorbing end-shock via the fixed NBR bumper.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X120 the Right Cylinder?
When sizing this 80 mm bore unit, consider the SDAD63 which outputs 1401.5 N at 0.5 MPa, or step up to the SDAD100 providing 3524.9 N at 0.5 MPa. The through-rod design inherently resists twisting, allowing you to mount a tool on one end and a dog on the opposite end simultaneously. Ensure you leave clearance for the rod exiting both sides.
This model yields a safe working load of roughly 1361 N, or a vertical lift capacity of about 115.6 kg with a 2:1 margin. Note that a standard cylinder drifts when air is lost or the valve is centered; the fixed bumper only decelerates near stroke end and never acts as a lock. 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 SDAD80X120 FAQ
The push and pull forces are identical due to the double-rod design. It generates 2267.8 N at 0.5 MPa and 3175 N at 0.7 MPa. The theoretical maximum force is 463 kgf at 1.0 MPa. Operating pressure ranges from 0.15 to 1.0 MPa.
No, this specific SKU lacks a piston magnet and cannot host reed or electronic switches. You must select the -S variant to enable sensing. However, the through-rod allows you to mount a dog or mechanical target on the opposite end to trigger an external sensor.
