Airtac PBD Pen-shaped Double Rod Cylinder PBD6X25
The AirTAC PBD Pen-shaped Double Rod Cylinder PBD6X25 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 Ø6mm bore, 25mm stroke.

About the Airtac PBD Pen-shaped Double Rod Cylinder PBD6X25
The AirTAC PBD6X25 is a double-acting, double-rod pen-size mini cylinder. A piston rod exits both covers on a single piston, meaning both chambers act on the same rod-side annular area. This geometry yields identical push and pull forces, giving you about 10.6 N of thrust in both 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. Built with SUS304 stainless steel, the slim body saves space in tight jigs. The bore uses an M5x0.8 air port, and a fixed TPU bumper at each end decelerates the last few millimeters of travel.

| Rod diameter | Ø3 mm (both ends) |
| Stroke | 25 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 50 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 (Ø6mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 10.6 N | 10.6 N |
| 0.7 MPa (max) | 14.8 N | 14.8 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 PBD6X25 Is Used
Symmetric Wire Feeder
Pushes and pulls a delicate wire guide with equal 10.6 N force, preventing slack on the return stroke.
Dual-Side Micro Transfer
Uses the spare rod end to mount a second pick finger, moving tiny electronic parts simultaneously.
Lightweight Lift Jig
Lifts a 0.5 kg sensor bracket vertically using twin rods to resist twist during the upstroke.
Is the Airtac PBD Pen-shaped Double Rod Cylinder PBD6X25 the Right Cylinder?
This 6 mm bore generates 10.6 N at 0.5 MPa and 14.8 N at the 0.7 MPa maximum. If you need less force, there is no smaller PBD bore, so look at reducing pressure. If your duty cycle needs more power, stepping up to the 10 mm bore raises output to 33.0 N at 0.5 MPa. Because rods protrude from both covers, you must layout clearance at both ends for the full 25 mm stroke. Confirm your ordering essentials: bore, stroke, no magnet, and mounting option.
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 PBD6X25 FAQ
It provides equal push and pull forces of 10.6 N at 0.5 MPa and 14.8 N at 0.7 MPa. The maximum operating pressure is 0.7 MPa.
No, the piston will drift without live pressure. The fixed TPU bumper only decelerates near stroke end and does not act as a lock. You need an external stop or rod lock for fail-safe holding.
