Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125S
The AirTAC PBD Pen-shaped Double Rod Cylinder PBD10X125S 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 PBD10X125S
The AirTAC PBD10X125S is a double-acting, double-rod pen-size mini cylinder with a 10mm bore and 125mm stroke. Because a rod exits both covers on one piston, the chambers act on the same annular area, yielding 33 N of force in both push and pull directions at 0.5 MPa. The twin rods resist twist better than a single rod and provide a spare end to mount a sensor flag or second tool.
This unit includes a built-in piston magnet for electronic or reed switches. It features a slim SUS304 stainless body, an M5x0.8 air port, and a fixed TPU bumper at each end. Note that the 125mm stroke exceeds the 100mm standard maximum for this bore, making it a non-standard, made-to-order configuration.
Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125S Technical Specifications
| Model | Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125S |
|---|---|
| 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 PBD10X125S Is Used
Dual-Side Transfer
Pushes a part forward on the extend stroke and pulls a second part back on retract, using the equal 33 N force both ways to keep cycle times balanced.
Sensor-Flagged Index
Uses the spare rod end to carry a physical flag for a reed switch, confirming position without loading the primary work tool on the opposite side.
Symmetric Clamp
Secures a delicate workpiece from two faces simultaneously, relying on the twin rods to resist twist and prevent jaw rotation during clamping.
Is the Airtac PBD Pen-shaped Double Rod Cylinder PBD10X125S the Right Cylinder?
Selecting this model means sizing for symmetric duty: it delivers 33 N both ways at 0.5 MPa. If you need less force, the 6mm bore provides 10.6 N; if you need more, the 12mm bore offers 46.7 N.
Because both ends protrude, ensure you leave rod clearance across the full 125mm stroke. The Ø4mm rod is built for coaxial thrust, so over this extended length or with off-axis loads, add an external linear bearing to prevent side load. Confirm your ordering essentials: 10mm bore, 125mm non-standard stroke, S magnet, and mounting choice.
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 PBD10X125S FAQ
It delivers an equal push and pull force of 33 N at 0.5 MPa and 46.2 N at the maximum operating pressure of 0.7 MPa. Because a rod occupies both chambers, the push and pull forces are identical.
No, the piston will drift without live pressure. The fixed TPU bumper only decelerates the piston near the stroke end and does not act as a lock. You must use an external stop or rod lock for fail-safe holding.
