Airtac SDAD Double Rod Slim Cylinder SDAD25X30SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X30SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 30mm 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 SDAD25X30SB
The AirTAC SDAD25X30SB 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, giving you exactly 206.2 N of push and pull force at 0.5 MPa. This symmetric output is ideal for balancing loads without tweaking pressure regulators.
Equipped with a built-in magnet (-S) for AirTAC reed or electronic switches and male M8x1.25 threads (-B) on both rod ends, it simplifies dual-end tooling. The short body saves axial mounting depth, while the fixed NBR bumper absorbs end-of-stroke shock without acting as a lock.
Airtac SDAD Double Rod Slim Cylinder SDAD25X30SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X30SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 30 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 SDAD25X30SB Is Used
Symmetric Transfer Chuck
Grips and moves delicate wafers using equal 206.2 N push/pull force, preventing asymmetric twisting during bidirectional handling.
Dual-End Guiding Jig
Uses the male M8x1.25 rod on the front to drive a clamp while the rear end mounts a switch dog for precise position feedback.
Compact Flap Folder
Fits into shallow packaging machinery frames using its short riveted body, folding carton flaps with consistent 288.6 N at 0.7 MPa.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X30SB the Right Cylinder?
When sizing this 25 mm bore, compare it directly with its neighbors: the SDAD20 provides 131.9 N at 0.5 MPa, whereas the SDAD32 jumps to 345.6 N. The SDAD25X30SB sits perfectly in the middle at 206.2 N, offering a safe working load of roughly 124 N for a 2:1 margin, or a vertical lift capacity of about 10.5 kg. The through-rod design inherently resists twisting, letting you mount a tool on one end and a position dog on the other.
Remember that a standard double-acting cylinder drifts when air is removed or the valve centers—the fixed bumper only decelerates the stroke end, it does not lock the load. For load holding without live pressure, install an external rod lock or pilot-operated check valve. This specific configuration includes the -S magnet for sensing and -B male M8x1.25 rod threads on both ends, paired with 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 SDAD25X30SB FAQ
The double-rod design provides equal force 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, with a proof pressure of 1.5 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke near the end; it is not a brake. For load holding, you must add an external rod lock or pilot-operated check valve.
