The AirTAC PBD Pen-shaped Double Rod Cylinder PBD6X40S 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.
The AirTAC PBD6X40S is a double-acting, double-rod pen-size mini cylinder with a 6 mm bore and 40 mm stroke. Because a rod exits both covers sharing one piston, push and pull forces are equal at 10.6 N at 0.5 MPa. The twin rods resist twist better than a single rod and provide a spare end for a sensor flag or second tool.
The slim SUS304 stainless body saves space in tight jigs. It features an M5x0.8 air port, an M5x0.8 rod-end thread, and a fixed TPU bumper at each end. The S suffix indicates a built-in piston magnet for position sensing.

| 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) |

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.
| 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.

Moves small electronic parts from one belt to another using both rod ends simultaneously for symmetric, equal-force pushing and pulling.
Uses the spare rod end to carry a flag for a reed or electronic switch, confirming position without extra mounting hardware.
Secures delicate wire harnesses from both sides. The twin rods resist rotation, keeping the clamping face perfectly aligned.
This 6 mm bore generates 10.6 N of force in both directions at 0.5 MPa. If you need less force, confirm if a smaller pen cylinder fits, or step up to the 10 mm bore for 33.0 N. Remember that both ends require rod clearance across the full 40 mm stroke. When ordering, confirm the bore, stroke, S magnet, and mounting accessories.
The thin Ø3 mm rod is built for coaxial thrust, so over long strokes or off-axis loads, add an external guide or linear bearing to prevent side load damage. The fixed TPU bumper only decelerates the last few mm, so at higher speeds with real mass, meter-out the exhaust or add an external shock absorber.
Quick checklist
The push and pull forces are equal because both chambers act on the same rod-side area. It outputs 10.6 N at 0.5 MPa and 14.8 N at the maximum operating pressure of 0.7 MPa.
No, a plain cylinder drifts when air is lost. 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 for fail-safe holding.
