Airtac SDAD Double Rod Slim Cylinder SDAD25X15S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X15S 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 SDAD25X15S
The AirTAC SDAD25X15S is a compact double-acting cylinder featuring a 25mm bore and 15mm stroke. A piston rod extends from both ends of the riveted body, creating identical annular areas. This geometry ensures push and pull forces match exactly at 206.2 N each way under 0.5 MPa, delivering balanced power for symmetric loads.
Equipped with a built-in magnet (-S), this unit reads position via reed or electronic switches housed in the body grooves. The short 15mm stroke and fixed NBR bumpers make it exceptionally space-efficient, while the 10mm through-rod resists twisting. It operates smoothly between 30-500 mm/s, handling a safe working load of roughly 124 N or a 10.5 kg vertical lift with a 2:1 safety margin.
Airtac SDAD Double Rod Slim Cylinder SDAD25X15S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X15S |
|---|---|
| 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 SDAD25X15S Is Used
Gripper Jaw Sync
Drives opposing gripper fingers with identical 206.2 N push-pull force, ensuring perfectly centered clamping on delicate machined parts.
Divert Gate Actuation
Uses the through-rod's anti-twist resistance to hold a sorting flap steady on a packaging line, with a position switch mounted on the unused rod end.
Micro-Press Pinning
Delivers a precise 15mm insertion stroke for driving locating pins, relying on the fixed NBR bumper to absorb the end-of-stroke shock.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X15S the Right Cylinder?
When sizing this 25mm bore unit, consider the neighbouring capacities at 0.5 MPa. Stepping down to the SDAD20 yields 131.9 N, whereas moving up to the SDAD32 provides 345.6 N. This SDAD25X15S sits comfortably in the middle, offering 206.2 N of equal bidirectional force. The dual-end through-rod allows mounting a tool on one side and a position dog on the opposite end simultaneously.
This configuration includes the -S magnet for switch readiness and female M5x0.8 rod-end threads on both sides, fed by an M5x0.8 air port. Remember that the fixed NBR bumper only decelerates the stroke end; it will not hold a load if air pressure drops. For vertical 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 SDAD25X15S FAQ
Because the double-rod design creates equal annular areas, force is identical in both directions: 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa. The theoretical maximum is 42 kgf at 1.0 MPa, which is the maximum operating pressure.
Yes. The through-rod extends from both sides, allowing you to drive a workpiece on one end while mounting a dog for a reed or electronic switch on the opposite end. The -S magnet enables this position sensing.
