Airtac SDAD Double Rod Slim Cylinder SDAD80X25
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X25 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 25mm 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 SDAD80X25
The AirTAC SDAD80X25 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, delivering an equal push and pull force of 2267.8 N at 0.5 MPa. This symmetry is essential when driving loads that require consistent momentum in both directions.
A 25 mm stroke keeps the overall axial depth remarkably short for an 80 mm bore unit. The piston rod measures 25 mm at each end, utilizing a PT3/8 air port. End-of-stroke energy is managed solely by a fixed NBR bumper, which decelerates the mass near the limits rather than acting as an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD80X25 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X25 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 25 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 SDAD80X25 Is Used
Symmetric Lift Station
Drives a 115 kg vertical lift platform where the equal 2267.8 N push and pull force ensures smooth elevation and descent without momentum shifts.
Anti-Rotation Guide
Lifts a heavy precision fixture using the 25 mm through-rod to resist twisting, maintaining strict parallelism without external linear bearings.
Dual-End Transfer
Pushes a workpiece carrier from one side while the opposite rod end simultaneously trips a mechanical dog, saving axial space in the cell.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X25 the Right Cylinder?
When sizing this 80 mm bore model, consider the adjacent options. 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 SDAD80X25 variant provides a safe working load of roughly 1361 N, allowing a vertical lift of approximately 115.6 kg with a 2:1 safety margin.
The through-rod geometry inherently resists twisting, allowing you to mount a tool on one end and a dog on the opposite side. This specific SKU lacks a piston magnet, so it cannot accept reed or electronic switches. Note that a plain cylinder drifts when air is lost or the valve centers; use an external rod lock or pilot-operated check valve for load holding. Rod-end threads are female M14x1.5.
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 SDAD80X25 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.
Yes, the through-rod exits both sides, allowing you to drive a load on one end and mount a dog on the other. This configuration also helps resist rotation during operation.
