Airtac SDAD Double Rod Slim Cylinder SDAD12X25S
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD12X25S 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 SDAD12X25S
The AirTAC SDAD12X25S is a compact double-acting cylinder featuring a 6mm through-rod exiting both ends of its short riveted body. Because the rod occupies both chambers, the annular area is identical on extend and retract, yielding exactly 42.4 N of push and pull force at 0.5 MPa. This symmetric output is ideal for delicate mechanisms requiring balanced resistance.
The built-in magnet enables position detection via AirTAC reed or electronic switches mounted directly into the body sensor grooves. End-of-stroke deceleration relies on a fixed NBR bumper rather than an adjustable air cushion. With a 25mm stroke and M5x0.8 port, this thin-profile unit fits where round-body or larger profile cylinders cannot.
Airtac SDAD Double Rod Slim Cylinder SDAD12X25S Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD12X25S |
|---|---|
| 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 SDAD12X25S Is Used
Micro-Grip Transfer
Picks and places small electronic chips using equal 42.4 N push/pull force to avoid part deformation during bidirectional transfers.
Symmetric Clamping Jig
Secures a thin workpiece from both sides simultaneously, leveraging the anti-rotation through-rod to keep the tooling perfectly aligned.
Lab Dispense Head
Mounts a valve on the front rod and a position dog on the rear rod, using the compact 12mm body to fit inside tight analytical equipment.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD12X25S the Right Cylinder?
When sizing this 12mm bore unit, consider the adjacent SDAD16 which provides 86.4 N at 0.5 MPa for heavier loads, while the SDAD12X25S itself offers a safe working load of roughly 25 N (about 60 percent of its 42.4 N rating) and can vertically lift approximately 2.2 kg with a 2:1 safety margin. The through-rod design resists twisting and permits driving a tool on one end while mounting a dog on the opposite end.
This configuration includes the female M3x0.5 rod-end thread on both sides and the S option for switch readiness. Note that a plain cylinder does not hold position on air loss or valve centring; the piston drifts and the fixed bumper only decelerates near stroke end. For 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 SDAD12X25S FAQ
Because the double-rod design provides equal annular area in both directions, 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 S option provides a built-in piston magnet for AirTAC reed or electronic switches. However, the cylinder does not hold load on air loss; you need an external rod lock or pilot-operated check valve for position holding.
