Airtac SDAD Double Rod Slim Cylinder SDAD25X130SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X130SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 130mm 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 SDAD25X130SB
The AirTAC SDAD25X130SB 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 in each direction, yielding equal push and pull forces of 206.2 N at 0.5 MPa. This symmetric thrust is a major advantage for loads requiring consistent drive and retraction energy.
The integrated piston magnet (-S) allows tracking via reed or electronic switches, while the male M8x1.25 threads (-B) on both rod ends simplify direct tool mounting. A fixed NBR bumper at each end decelerates the stroke end, and the short body geometry saves axial mounting depth where larger profile cylinders will not fit.
Airtac SDAD Double Rod Slim Cylinder SDAD25X130SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X130SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 130 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 SDAD25X130SB Is Used
Symmetric Transfer Jaws
Drives a gripping jaw on one end while the opposite rod end mounts a position dog, using the equal 206.2 N force to securely shift components between machining centers.
Anti-Twist Edge Guide
The through-rod geometry resists rotation during high-speed web guiding, maintaining precise alignment without lateral drift on packaging films.
Balanced Vertical Lift
Lifts a 10.5 kg fixture with a 2:1 safety margin, relying on the matched extend and retract thrust to prevent sudden drops when reversing direction.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X130SB the Right Cylinder?
When sizing this unit, consider the adjacent bores: the SDAD20 provides 131.9 N at 0.5 MPa, while the SDAD32 offers 345.6 N. This 25mm bore provides a safe working load of roughly 124 N (about 60% of the 0.5 MPa figure) and can vertically lift around 10.5 kg with a 2:1 safety margin. The through-rod design resists twisting, letting you drive a tool on one end and a dog on the other.
Remember that a plain cylinder drifts when air is lost or the valve is centered; the fixed NBR bumper only decelerates near stroke end and does not act as a lock. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration includes the M5x0.8 air port, built-in magnet, and male M8x1.25 rod threads on both sides.
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 SDAD25X130SB FAQ
The push and pull forces are equal because the rod exits both ends. It generates 206.2 N at 0.5 MPa and 288.6 N at 0.7 MPa in both directions. The theoretical maximum is 42 kgf at 1.0 MPa, with a proof pressure of 1.5 MPa.
Yes, the double-rod design allows you to attach a work tool to the male M8x1.25 thread on one end while using the opposite end for a dog or switch. The built-in magnet (-S) supports AirTAC reed or electronic switches for position detection.
