Airtac SDAD Double Rod Slim Cylinder SDAD12X45S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X45S is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm bore, 45mm 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 SDAD12X45S
The AirTAC SDAD12X45S is a compact double-acting cylinder featuring a 12mm bore and 45mm stroke. A 6mm piston rod exits both ends of the riveted body, creating identical annular areas. This geometry ensures push force equals pull force, delivering exactly 42.4 N at 0.5 MPa in each direction for symmetric load handling.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for position sensing. The short body design minimizes axial footprint, while fixed NBR bumpers absorb end-of-stroke shock. Operating between 0.15 and 1.0 MPa, it achieves a safe working load of roughly 25 N, or a 2.2 kg vertical lift with a 2:1 safety margin.
Airtac SDAD Double Rod Slim Cylinder SDAD12X45S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X45S |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 45 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 SDAD12X45S Is Used
Micro Gripper Actuation
Drives small parallel grippers where the 42.4 N equal push and pull force ensures symmetric clamping on delicate laboratory samples.
PCB Component Placement
Utilizes the dual-end through-rod to mount a pickup nozzle on one side and a position detection dog on the other for precise electronics assembly.
Miniature Spot Welding
Applies steady electrode pressure in tight fabrication cells, leveraging the anti-rotation properties of the double rod to maintain tip alignment.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X45S the Right Cylinder?
When sizing this 12mm bore unit, consider the adjacent SDAD16X45S if your application requires greater thrust, as it yields 86.4 N at 0.5 MPa. The SDAD12X45S is the smallest available option, making it ideal for ultra-tight spaces. It features a 6mm rod, female M3x0.5 rod-end threads, and an M5x0.8 air port. The included magnet enables switch integration.
The through-rod design resists twisting and permits mounting a tool on one end with a position dog on the opposite side. Remember that a standard cylinder drifts when air pressure is lost or the valve centers; the fixed NBR bumper only decelerates the stroke end and does not function as a lock. For secure load holding without live pressure, install an external rod lock or pilot-operated check valve.
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 SDAD12X45S FAQ
Because the rod exits both ends, the force is identical in both directions. It provides 42.4 N at 0.5 MPa, 59.4 N at 0.7 MPa, and a maximum theoretical output of 9 kgf at 1.0 MPa.
The through-rod prevents twisting during operation and allows you to drive a tool on one end while mounting a reed or electronic switch dog on the opposite end, maximizing spatial efficiency in compact machinery.
