Airtac SDAD Double Rod Slim Cylinder SDAD80X15
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD80X15 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø80mm bore, 15mm 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 SDAD80X15
The AirTAC SDAD80X15 is a compact double-acting cylinder featuring a 25mm through-rod exiting both ends of its riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, yielding exactly 2267.8 N of force at 0.5 MPa whether extending or retracting. This symmetric output is ideal for balancing heavy tooling.
With a brief 15mm stroke, the unit minimizes axial footprint while enduring operating pressures up to 1.0 MPa. End-of-travel deceleration relies on a fixed NBR bumper rather than an adjustable cushion. Note this specific SKU lacks a piston magnet, so position sensing is not supported without upgrading to the -S variant.
Airtac SDAD Double Rod Slim Cylinder SDAD80X15 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD80X15 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø80 mm |
| Stroke | 15 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 SDAD80X15 Is Used
Symmetric Lift Stations
Provides identical 2267.8 N push and pull forces to raise and lower heavy machining fixtures without load imbalance.
Anti-Twist Guiding
The 25mm dual-end rod prevents rotation during high-force clamping, maintaining precise alignment for critical part inspection.
Dual-End Tooling
Drive a 15mm stamping operation on the front face while using the rear rod extension to mechanically trip a limit dog.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD80X15 the Right Cylinder?
When sizing this 80mm bore, stepping down to the SDAD63 yields 1401.5 N at 0.5 MPa, whereas moving up to the SDAD100 provides 3524.9 N. This SDAD80X15 bridges that gap with 2267.8 N, offering a safe working load around 1361 N for a 2:1 margin. The 25mm through-rod strongly resists twisting, allowing you to mount a work tool on one end and a dog on the opposite side simultaneously.
This configuration uses a PT3/8 port and female M14x1.5 rod threads. It cannot hold a vertical load if air pressure drops, as the piston will drift; install an external rod lock or pilot-operated check valve for secure load holding. Since no -S magnet is present here, magnetic switches cannot be fitted.
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 SDAD80X15 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. The maximum operating pressure is 1.0 MPa.
Yes, the through-rod extends from both sides, allowing you to drive a tool on one end and mount a dog on the other. The 25mm rod also resists twisting, though you must leave clearance for the rear rod movement.
