Airtac SDAD Double Rod Slim Cylinder SDAD25X15
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X15 is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm 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 SDAD25X15
The AirTAC SDAD25X15 is a compact double-acting 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 206.2 N at 0.5 MPa. This symmetry is essential for mechanisms requiring consistent kinetic output in both travel directions.
With a 10 mm piston rod and a short 15 mm stroke, this unit saves axial mounting depth where a larger profile cylinder will not fit. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Note this specific SKU lacks a piston magnet, so it cannot directly host reed or electronic switches.
Airtac SDAD Double Rod Slim Cylinder SDAD25X15 Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X15 |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 15 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 (Ø25mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 SDAD25X15 Is Used
Symmetric Clamping
Provides 206.2 N of equal force extending and retracting to secure workpieces without shifting the load during clamp release.
Anti-Twist Guide
The double-rod construction resists rotation, keeping a 15 mm stroke gauging head perfectly aligned in tight fixture clearances.
Dual-End Tooling
Drives a forming punch on the front face while the opposing rod end mechanically trips an external limit dog simultaneously.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X15 the Right Cylinder?
When sizing this 25 mm bore, compare its 206.2 N output at 0.5 MPa both ways: stepping down to the SDAD20 yields 131.9 N, while stepping up to the SDAD32 provides 345.6 N. The through-rod geometry resists twisting and allows mounting a tool on one end with a dog on the opposite side. A safe working load is roughly 124 N, allowing a vertical lift of about 10.5 kg with a 2:1 margin.
This configuration uses an M5x0.8 port, female M5x0.8 rod-end threads, and operates at 30-500 mm/s. Remember that a standard cylinder does not hold position if air pressure drops or the valve centers; the piston drifts. 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 SDAD25X15 FAQ
Because the rod exits both ends, push and pull forces are equal. It generates 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa in both directions.
No, this specific SKU does not include a piston magnet. You must select the -S option variant to use AirTAC reed or electronic switches in the body sensor grooves.
