Airtac SDAD Double Rod Slim Cylinder SDAD25X80SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X80SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 80mm 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 SDAD25X80SB
The AirTAC SDAD25X80SB is a double-acting, double-rod compact cylinder engineered for symmetric operation. Because the piston rod exits both ends of the riveted body, the annular areas match, yielding identical push and pull forces of 206.2 N at 0.5 MPa. This through-rod geometry inherently resists mechanical twisting, providing stable guidance for precision tasks.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches, this 25 mm bore unit features male M8x1.25 threads (-B) on both 10 mm rod ends. The short body footprint saves axial mounting depth, while the fixed NBR bumpers absorb end-of-stroke shock across the 30-500 mm/s speed range.
Airtac SDAD Double Rod Slim Cylinder SDAD25X80SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X80SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 80 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 SDAD25X80SB Is Used
Gripper Synchronization
Drives opposing gripper jaws with equal 206.2 N force in both directions, ensuring perfectly centered clamping on delicate electronic components.
Dual-End Transfer
Mounts a pick-and-place head on one male M8 rod end while a magnetic switch tracks the 80 mm stroke on the opposite end, saving axial space.
Anti-Rotation Pusher
Pushes small cartons on a packaging line without twisting, utilizing the through-rod stability to keep the pusher plate perfectly aligned.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X80SB the Right Cylinder?
When sizing this model, consider the neighboring bores: the SDAD20 provides 131.9 N at 0.5 MPa, while the SDAD32 offers 345.6 N at 0.5 MPa. The 25 mm bore strikes a middle ground, delivering a safe working load of roughly 124 N (about 60% of its 0.5 MPa rating) and a vertical lift capacity of approximately 10.5 kg with a 2:1 safety margin.
The dual male M8x1.25 rod ends allow mounting a tool on one side and a position dog on the other. Note that a standard cylinder drifts when air is removed or a valve centers; the fixed NBR bumper only decelerates the stroke end without locking the load. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This configuration uses an M5x0.8 port.
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 SDAD25X80SB FAQ
Because the rod occupies both chambers, the push and pull forces are identical: 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.
Yes, the through-rod design features male M8x1.25 threads on both ends, allowing you to drive a tool on one side while mounting an AirTAC reed or electronic switch via the built-in magnet on the other.
