Airtac SDAD Double Rod Slim Cylinder SDAD12X25SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X25SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm bore, 25mm 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 SDAD12X25SB
The AirTAC SDAD12X25SB is a 12 mm bore, double-acting compact cylinder featuring a through-rod that exits both ends of its short riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, giving you exactly 42.4 N of push and pull force at 0.5 MPa. This symmetric output is perfect for delicate, balanced operations.
This specific configuration includes a built-in magnet for position sensing alongside male M5x0.8 threaded rods on both ends. The fixed NBR bumper decelerates the piston near stroke end, while the M5x0.8 air port keeps the overall footprint exceptionally tight for densely packed machinery.
Airtac SDAD Double Rod Slim Cylinder SDAD12X25SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X25SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 25 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M3×0.5 female / M5×0.8 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 50 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 (Ø12mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 42 N |
| 0.7 MPa | 59 N |
| Max (@1.0 MPa) | 9 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 SDAD12X25SB Is Used
Micro-Grip Transfer
Drives a small parallel gripper on the front rod while the rear rod carries a dog to trigger a solid-state sensor, utilizing the equal 42.4 N force for stable part handling.
Lab Dispense Head
Mounts a fluid valve on the male M5x0.8 rod end to push and retract symmetrically, with the compact 12 mm body fitting easily between dense lab automation frames.
PCB Pusher Assembly
Uses the anti-rotation through-rod to push a delicate printed circuit board into a test fixture without twisting, ensuring the male-threaded tool stays perfectly aligned.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X25SB the Right Cylinder?
When sizing this 12 mm bore, compare it to the adjacent SDAD16, which raises the bidirectional force to 86.4 N at 0.5 MPa. If 42.4 N is excessive for your payload, note there is no smaller standard SDAD bore, so you must restrict the operating pressure instead. A safe working load is approximately 25 N, yielding a vertical lift capacity of roughly 2.2 kg with a 2:1 safety margin.
The through-rod design prevents twisting and allows you to mount a tool on one end and a dog on the opposite end. Remember that a plain cylinder drifts when air is lost or the valve centers—the fixed bumper only decelerates near the stroke end and will not hold the load; use an external rod lock or pilot-operated check valve for load holding. This SB variant confirms the 25 mm stroke, M5x0.8 port, internal magnet for reed or electronic switches, and male M5x0.8 rod threads.
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 SDAD12X25SB FAQ
Because the rod exits both ends, the push and pull forces are equal: 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a theoretical maximum of 9 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
The through-rod resists twisting under load and allows you to mount a tool on one end while using the opposite end to trigger a reed or electronic switch. This SB variant also features male M5x0.8 threads on both rod ends for secure tool attachment.
