Airtac SDAD Double Rod Slim Cylinder SDAD12X40SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X40SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm bore, 40mm 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 SDAD12X40SB
The AirTAC SDAD12X40SB is a compact double-acting cylinder featuring a 12mm bore and 40mm stroke. A 6mm piston rod exits both ends of the riveted body, creating equal annular areas. This geometry yields identical push and pull forces of 42.4 N at 0.5 MPa, ensuring symmetric motion for delicate mechanisms.
This specific configuration includes a built-in magnet for position sensing alongside male M5x0.8 rod threads on both ends. The short body design drastically reduces axial mounting depth. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD12X40SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X40SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 40 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 SDAD12X40SB Is Used
Micro-Gripper Actuation
Drives a symmetrical gripping jaw using the 42.4 N equal force, ensuring delicate components are clamped without rotational deflection.
Dual-End Transfer Pusher
Uses the male M5x0.8 rod ends to push a part on one side while simultaneously triggering a reed switch on the opposite end for timing.
Lab Sample Indexing
Indexes small medical vials in a tight envelope, capitalizing on the 12mm compact footprint and fixed NBR bumper for soft end stops.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X40SB the Right Cylinder?
When sizing this unit, stepping down is not an option as 12mm is the smallest available bore. Moving up to the SDAD16 increases the bidirectional force to 86.4 N at 0.5 MPa, which is double the output. For the SDAD12X40SB, the safe working load is approximately 25 N, and it can vertically lift about 2.2 kg with a 2:1 safety margin.
The through-rod design prevents twisting and allows mounting a tool on one end while a dog triggers a switch on the opposite end. Note that a plain cylinder drifts when air is lost; use an external rod lock or pilot-operated check valve for load holding. This model features an M5x0.8 port, a 40mm stroke, the -S magnet for reed or electronic switches, and male -B 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 SDAD12X40SB FAQ
Because the double-rod design creates equal annular areas, the push and pull forces are identical: 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 in both directions.
The through-rod resists twisting under load and allows you to mount a tool on one end and a sensor dog on the other. This specific SB variant also features male M5x0.8 threads on both rod ends for easier nut mounting.
