Airtac SDAD Double Rod Slim Cylinder SDAD80X20
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X20 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 20mm 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 SDAD80X20
The AirTAC SDAD80X20 is a compact double-acting cylinder featuring a piston rod protruding from both ends of its riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetry is ideal for driving loads that require consistent momentum in both directions.
A 25 mm through-rod resists twisting during operation and allows you to mount a work tool on one end while attaching a dog or secondary mechanism on the opposite side. The short body design minimizes axial footprint, while a fixed NBR bumper at each end absorbs end-of-stroke shock. This specific SKU lacks a piston magnet and therefore cannot support position sensing.
Airtac SDAD Double Rod Slim Cylinder SDAD80X20 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X20 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 20 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 SDAD80X20 Is Used
Symmetric Lift Stations
Drives vertical lifting platforms requiring identical force up and down, utilizing the 2267.8 N output to raise and lower 115 kg payloads smoothly.
Anti-Twist Guiding
Handles heavy-duty gripping tasks where the 25 mm through-rod prevents mechanical rotation, ensuring precise alignment without lateral deflection.
Dual-End Tooling
Mounts a forming die on the primary rod end and a mechanical dog on the opposing end to trigger external physical limit switches in tight spaces.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X20 the Right Cylinder?
When sizing this 80 mm bore unit, compare its 2267.8 N force at 0.5 MPa with neighbouring models. Stepping down to the SDAD63 provides 1401.5 N, whereas moving up to the SDAD100 yields 3524.9 N. With a 2:1 safety margin, the SDAD80X20 can vertically lift approximately 115.6 kg, equating to a safe working load of roughly 1361 N.
The through-rod geometry provides excellent anti-rotation stability and dual-end mounting flexibility. Note that a standard cylinder drifts when air pressure is lost or the valve is centered, as the fixed bumper only decelerates near stroke end and does not act as a lock; utilize an external rod lock or pilot-operated check valve for secure load holding. This configuration features a 20 mm stroke, PT3/8 port, female M14x1.5 rod-end threads on both sides, and no magnet.
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 SDAD80X20 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 extends from both sides, allowing you to drive a tool on one end and mount a secondary fixture on the other. This configuration has no magnet, but choosing the -S variant enables reed or electronic switches for position feedback.
