Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125
The AirTAC PBD Pen-shaped Double Rod Cylinder PBD10X125 is a double-acting pen-size mini cylinder with a piston rod protruding from both covers. The twin rods share one piston, giving equal push and pull force, resisting rotation and providing a spare mounting or sensing end on a Ø10mm bore, 125mm stroke.

About the Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125
The AirTAC PBD10X125 is a double-acting, double-rod pen-size mini cylinder featuring a 10mm bore and a 125mm stroke. A piston rod exits both covers on a single piston, meaning both chambers act on the exact same rod-side annular area. This geometry delivers perfectly equal push and pull forces, giving you 33 N of thrust in both directions at 0.5 MPa.
Because 125mm exceeds the 100mm standard stroke maximum for this bore, this unit is non-standard and made-to-order. The twin Ø4mm stainless steel rods resist twist better than a single rod and provide a spare end for mounting a sensor flag or external stop. The slim SUS304 body saves space in tight jigs, while a fixed TPU bumper at each end decelerates the piston near stroke end. The air port is M5x0.8 and the rod-end thread is M8x1.0.

| Model | Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125 |
|---|---|
| Series | PBD JIS pen-size double-rod cylinder |
| Bore size | Ø10 mm |
| Rod diameter | Ø4 mm (both ends) |
| Stroke | 125 mm |
| Acting type | Double acting, double rod |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 100 mm |
Both chambers act on the rod-side annular area, so push and pull forces are equal. Piston rod and barrel are stainless steel. Confirm against the product label before installation.
Theoretical Output Force (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 33.0 N | 33.0 N |
| 0.7 MPa (max) | 46.2 N | 46.2 N |
Because a rod occupies both chambers, the effective area is identical on each side — push and pull forces match. Values are from the AirTAC thrust table (rod-side / pull column). Size with a friction margin.

Where the Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125 Is Used
Dual-Side Transfer
Pushes a part forward on the extend stroke and retracts a second fixture simultaneously, leveraging the equal force on both ends for balanced dual-side handling.
Symmetric Clamp
Clamps a workpiece from opposite sides using both rod ends, ensuring even pressure without requiring a larger bore or complex external guidance.
Sensor-Flagged Index
Uses the primary rod for motion while the spare rear rod carries a physical flag, triggering an external reed or electronic switch without extra brackets.
Is the Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125 the Right Cylinder?
Selecting this model means sizing both ways: the smaller 6mm bore yields 10.6 N at 0.5 MPa, while the larger 12mm bore provides 46.7 N. This 10mm bore hits a middle ground at 33 N. Since push equals pull, it is ideal for symmetric duty.
Remember that both ends need rod clearance across the full 125mm travel. The thin Ø4mm rod is built for coaxial thrust, so over this extended stroke or with off-axis loads, add an external linear bearing to prevent side-load damage. When ordering, confirm the 10mm bore, 125mm non-standard stroke, and your required mounting accessories.
Quick checklist
- ✓ Need equal force in both directions
- ✓ Second rod end for a sensor / stop / flag
- ✓ Better anti-rotation than a single rod
- ✓ Magnet (S) for sensors?
- ✓ Clearance for the rod on both ends
- ✓ Keep the load coaxial — avoid side load
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 0.7 MPa operating pressure.
- check Leave clearance for the rod at both ends.
- check Keep the load coaxial; avoid side load on the thin rods.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125 FAQ
It delivers an equal push and pull force of 33 N at 0.5 MPa and 46.2 N at 0.7 MPa. The maximum operating pressure is strictly 0.7 MPa. Because it is a double-rod design, both directions generate the exact same force.
No, a plain PBD does not hold position on air loss and the piston will drift. The fixed TPU bumper only decelerates the last few millimeters of travel; it is not a lock or brake. You must use an external stop or rod lock for fail-safe holding.
