Airtac PB Pen-type Cylinder PB12X30CBFA
The AirTAC Airtac PB Pen-type Cylinder PB12X30CBFA is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 30mm stroke. Its slim round barrel and back cover are stainless steel, the M5×0.8 ports keep plumbing compact, and the fast, low-friction piston suits high-cycle small-part handling.

About the Airtac PB Pen-type Cylinder PB12X30CBFA
The AirTAC PB12X30CBFA is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It yields a theoretical push of 56.5 N and pull of 46.7 N at 0.5 MPa, driven through an M5x0.8 air port. The slim SUS304 stainless barrel and screwed-in covers provide durability in damp or mildly corrosive environments while saving critical space on light end-of-arm tooling.
This specific configuration includes a CB double clevis back cover for pivoting loads and an FA mounting bracket for secure attachment. It relies on a fixed TPU bumper at each end to decelerate the stroke, and the Ø5 mm piston rod features an M10x1.0 rod-end thread for direct coupling. Because the rod is only 5 mm thick, it is built for coaxial thrust rather than off-axis side loads.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 30 mm |
| Acting type | Double acting |
| 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) |

Specifications follow the official AirTAC PB pen-size datasheet. Piston rod and barrel are stainless steel. Confirm bore, stroke and back-cover option against the product label before installation.
Theoretical Output Force (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 56.5 N | 46.7 N |
| 0.7 MPa (max) | 79.1 N | 65.4 N |
Values are taken from the AirTAC PB thrust table. Because pull acts on the rod-side annular area, pull force is always lower than push. Actual usable force is reduced by friction — size with a margin.

Where the Airtac PB Pen-type Cylinder PB12X30CBFA Is Used
PCB Depanelling Jigs
Actuates a small cutting blade or clamping arm in tight electronics assembly cells where the slim 12 mm barrel prevents collision with adjacent tooling.
Pouch Flap Opening
Deploys a suction probe to grip and open thin film packaging flaps, utilising the 46.7 N retract force to peel the material back smoothly at high cycle rates.
Diverter Gate Pusher
Pivots a lightweight sorting gate via the CB double clevis to redirect small plastic bottles on a conveyor line, benefiting from the FA bracket for rigid frame mounting.
Is the Airtac PB Pen-type Cylinder PB12X30CBFA the Right Cylinder?
When sizing this 12 mm bore unit, consider stepping down to the Ø10 bore if your load requires less force, which provides a 39.3 N push at 0.5 MPa. If you need more thrust, stepping up to the Ø16 bore offers a 100.5 N push at 0.5 MPa.
Remember that a plain PB-type cylinder drifts when air is lost or the valve is centred; the internal bumper only decelerates near the stroke end rather than locking the position, so an external rod lock is required for fail-safe holding. To order, confirm the 12 mm bore, 30 mm stroke, M5x0.8 port, CB double clevis back cover, and FA mount. No magnet is included on this SKU.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Slim pen body vs. a standard round cylinder
- ✓ Back cover: CB / U / R inlet direction
- ✓ Magnet (S) for sensors?
- ✓ Mounting: LB / FA / CJ or front thread
- ✓ 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 Keep the load coaxial; avoid side load on the thin rod.
- check Do not dismantle the front or back cover.
- check Fit dust caps to ports during long-term storage.
- check Installation by qualified personnel per AirTAC docs.
Airtac PB Pen-type Cylinder PB12X30CBFA FAQ
This double-acting cylinder generates a push of 56.5 N and a pull of 46.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields a 79.1 N push and a 65.4 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and uses an M5x0.8 port.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimetres; this is not an adjustable air cushion, so high-speed cycles with heavy tooling may require metering the exhaust or adding an external shock absorber. Additionally, it does not hold its load when air pressure is lost, meaning an external stop is needed for fail-safe positioning.
