Airtac SDAD Double Rod Slim Cylinder SDAD12X35SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X35SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø12mm bore, 35mm 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 SDAD12X35SB
The AirTAC SDAD12X35SB is a compact double-acting cylinder featuring a 6 mm piston rod exiting both ends of its riveted body. Because the rod occupies each chamber, the annular area matches on extend and retract, yielding an identical push and pull force of 42.4 N at 0.5 MPa. This symmetry prevents twisting during transit and allows you to drive a work tool on one side while tracking position with a switch on the opposite side.
Designed for tight spaces, the short footprint saves axial mounting depth where larger profile cylinders fail to fit. This specific configuration includes a built-in magnet for reed or electronic switches, plus male M5x0.8 threaded rods on both ends to secure your fixtures directly. End-of-stroke energy is managed by a fixed NBR bumper that decelerates the piston, operating reliably at speeds between 30 and 500 mm/s.
Airtac SDAD Double Rod Slim Cylinder SDAD12X35SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X35SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø12 mm |
| Stroke | 35 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 SDAD12X35SB Is Used
Micro-Gripper Actuation
Drives small clamping jaws with equal 42.4 N force in both directions, ensuring delicate electronic components are gripped securely without rotational deflection.
Dual-End Probe Mounting
Uses the through-rod to push a testing probe on one end while a dog on the opposite end trips a reed switch, verifying test completion in confined QA fixtures.
Symmetric Push-Pull Gates
Operates miniature diverter flaps where identical extend and retract forces are required to maintain balanced timing across a 35 mm stroke cycle.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X35SB the Right Cylinder?
When sizing this 12 mm bore unit, consider the adjacent SDAD16 option, which raises the output to 86.4 N at 0.5 MPa if your payload exceeds the safe working load of roughly 25 N (about 60 percent of the 42.4 N capacity). Going smaller is not standard in this series, making the 12 mm bore the baseline for light-duty tasks like lifting a 2.2 kg mass vertically with a 2:1 safety margin. The through-rod geometry provides excellent anti-rotation stability for guided mechanisms.
This model features a 35 mm stroke, an M5x0.8 air port, and male M5x0.8 rod threads on both ends. The included -S magnet enables position sensing with AirTAC reed or solid-state switches. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve centers; the fixed NBR bumper only decelerates near the stroke end and will not hold the load. For secure load holding without live pressure, install an external rod lock or a 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 SDAD12X35SB FAQ
Because the double-rod design provides equal annular area in both directions, 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.
Yes, the through-rod design allows you to mount a work tool on one end and a position dog on the other. This specific model includes the -B option, meaning both rods feature male M5x0.8 threads for easy fixture attachment, while the -S magnet enables switch tracking.
