Airtac SDAD Double Rod Slim Cylinder SDAD25X60SB
The AirTAC Airtac SDAD Double Rod Slim Cylinder SDAD25X60SB is a genuine double-acting COMPACT cylinder with a piston rod out BOTH ends (Ø25mm bore, 60mm 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 SDAD25X60SB
The AirTAC SDAD25X60SB is a compact double-acting cylinder featuring a through-rod that exits both ends of the riveted body. Because the rod occupies both chambers, the annular area is identical in each direction, giving exactly 206.2 N of push and pull force at 0.5 MPa. This symmetric output is essential for mechanisms requiring consistent actuation on extension and retraction.
This specific configuration includes a built-in piston magnet for AirTAC reed or electronic switches, along with male M8x1.25 rod threads on both ends. The short body design drastically reduces axial mounting depth compared to standard round-body options. End-of-stroke deceleration is handled by a fixed NBR bumper, which absorbs shock but is not an adjustable air cushion.
Airtac SDAD Double Rod Slim Cylinder SDAD25X60SB Technical Specifications
| Model | Airtac SDAD Double Rod Slim Cylinder SDAD25X60SB |
|---|---|
| Series | SDAD compact double-rod cylinder |
| Bore size | Ø25 mm |
| Stroke | 60 mm |
| Acting type | Double acting, rod both ends |
| Port size | M5×0.8 |
| Rod end thread | M5×0.8 female / M8×1.25 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 120 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 (Ø25mm)
| Pressure | Force (both directions) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 SDAD25X60SB Is Used
Symmetric Transfer Arms
Drives pick-and-place arms where the 206.2 N equal force ensures smooth acceleration and deceleration of gripper assemblies in both travel directions.
Anti-Rotation Guiding
The dual through-rod resists twisting torque during vertical clamping, maintaining precise alignment for parts with a 10.5 kg vertical lift margin.
Dual-End Tooling
Mounts a forming tool on the male M8x1.25 rod end while a position dog on the opposite end trips a reed or electronic switch for timing control.
Is the Airtac SDAD Double Rod Slim Cylinder SDAD25X60SB the Right Cylinder?
When sizing this unit, consider the neighboring bores: stepping down to the SDAD20 provides 131.9 N at 0.5 MPa, while stepping up to the SDAD32 yields 345.6 N at 0.5 MPa. For this 25 mm bore, the safe working load is approximately 124 N (about 60 percent of the 0.5 MPa figure), allowing a vertical lift of roughly 10.5 kg with a 2:1 safety margin. The through-rod geometry prevents twisting and permits mounting a tool on one end and a position dog on the opposite side.
This model is configured with a 60 mm stroke, an M5x0.8 air port, a built-in magnet (-S), and male M8x1.25 threads on both rods (-B). Note that a plain double-acting cylinder does not hold position if air pressure is lost or the valve is centered; the piston will drift. For load holding without live pressure, integrate 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 SDAD25X60SB FAQ
The push and pull forces are equal because of the double-rod design. It generates 206.2 N at 0.5 MPa, 288.6 N at 0.7 MPa, and a theoretical maximum of 42 kgf at 1.0 MPa. The maximum operating pressure is 1.0 MPa.
No, a plain double-acting cylinder drifts when air is lost or the valve is centered. The fixed NBR bumper only decelerates the stroke near the end; it does not act as a lock. For load holding, you must add an external rod lock or pilot-operated check valve.
