Airtac PBD Pen-shaped Double Rod Cylinder PBD6X40
The AirTAC PBD Pen-shaped Double Rod Cylinder PBD6X40 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, 40mm stroke.

About the Airtac PBD Pen-shaped Double Rod Cylinder PBD6X40
The AirTAC PBD6X40 is a double-acting, double-rod pen-size mini cylinder. A piston rod protrudes from both covers, meaning both chambers act on the same rod-side annular area. This geometry delivers exactly 10.6 N of push and pull at 0.5 MPa. The SUS304 stainless barrel and rods provide a slim footprint for compact jigs.
Because the twin rods share one piston, they resist twist better than a single rod. The second end can carry a sensor flag or external stop without extra hardware. The fixed TPU bumper at each end decelerates the last few millimeters of travel.
Airtac PBD Pen-shaped Double Rod Cylinder PBD6X40 Technical Specifications
| Model | Airtac PBD Pen-shaped Double Rod Cylinder PBD6X40 |
|---|---|
| Series | PBD JIS pen-size double-rod cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm (both ends) |
| Stroke | 40 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 PBD6X40 Is Used
Dual-Side Transfer
Pushes a part from one belt to another using one rod, while the opposite rod simultaneously retracts a second part for continuous indexing.
Symmetric Clamp
Clamps a thin workpiece from both sides simultaneously, utilizing the equal push and pull forces to keep delicate components centered.
Sensor-Flagged Index
Uses the primary rod for light thrusting while the spare rear rod end mounts a physical flag to trigger an external limit switch.
Is the Airtac PBD Pen-shaped Double Rod Cylinder PBD6X40 the Right Cylinder?
This 6 mm bore generates 10.6 N in both directions at 0.5 MPa. If your application requires less force, a smaller pen cylinder is appropriate, but for more thrust, stepping up to a 10 mm bore yields 33.0 N. Remember that both ends require rod clearance across the full 40 mm stroke. The air port is M5x0.8 and the rod-end thread is M5x0.8. Confirm your ordering essentials: bore, stroke, magnet (this model has none), and mounting.
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 PBD6X40 FAQ
The PBD6X40 provides an equal push and pull force 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, a plain double-rod cylinder drifts when air loss occurs. The fixed TPU bumper only decelerates near the stroke end and does not act as a lock. You need an external stop or rod lock to hold a load safely.
