Airtac SDAD Double Rod Slim Cylinder SDAD12X50SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X50SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm bore, 50mm 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 SDAD12X50SB
The AirTAC SDAD12X50SB is a compact double-acting pneumatic cylinder featuring a 12 mm bore and 50 mm stroke. Because the 6 mm piston rod exits both ends of the riveted body, the annular area remains identical in each chamber. This geometry ensures push and pull forces match exactly, yielding 42.4 N at 0.5 MPa in either direction. The short body profile saves valuable axial mounting depth where larger profile cylinders cannot fit.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, plus male M5x0.8 thread rods on both ends to simplify tool mounting. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. Operating speed spans 30-500 mm/s within a temperature range of -20 to +70 C.
Airtac SDAD Double Rod Slim Cylinder SDAD12X50SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X50SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 50 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 SDAD12X50SB Is Used
Micro-Gripper Actuation
Drives small parallel grippers where the male M5 rod end threads directly into the jaw block, utilizing the 42.4 N equal force for secure part pick-and-place.
Symmetric Transfer Pusher
Pushes a light 2.2 kg electronics carrier between two stations, relying on the through-rod anti-rotation properties to prevent binding during lateral transfer.
Dual-End Component Sorting
Mounts a deflector flap on one rod end and a magnetic dog on the opposite end, allowing an external reed switch to confirm flap position without blocking the work area.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X50SB the Right Cylinder?
When sizing this 12 mm bore unit, consider the adjacent SDAD16 which raises output to 86.4 N at 0.5 MPa if your application demands more thrust. Conversely, the SDAD12 represents the smallest available option in this family. Calculations on the 42.4 N figure suggest a safe working load around 25 N (roughly 60 percent capacity) and a vertical lift capability near 2.2 kg with a 2:1 safety margin.
The through-rod design inherently resists twisting, allowing you to drive a tool on one end while mounting a position dog on the opposite side. Remember that a plain double-acting cylinder drifts when air pressure drops or the valve centers; the NBR bumper only decelerates the stroke end and cannot hold a load. For load holding without live pressure, integrate an external rod lock or pilot-operated check valve. This model features an M5x0.8 port, male M5x0.8 rods, and the -S magnet.
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 SDAD12X50SB FAQ
Because the rod occupies both chambers, force is equal in both directions: 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.
Yes, the double-rod design allows you to mount a tool on one end and a switch dog on the other. The male M5x0.8 threads on both ends simplify mounting, while the through-rod resists twisting. Note that the fixed NBR bumper only decelerates the stroke end; it does not lock the position.
