Airtac PB Pen-type Cylinder PB12X75CBFA
The AirTAC PB Pen-type Cylinder PB12X75CBFA is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 75mm 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 PB12X75CBFA
The AirTAC PB12X75CBFA is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It delivers 56.5 N of push and 46.7 N of pull at 0.5 MPa. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments, while keeping weight low for end-of-arm tooling. This configuration includes a CB double clevis back cover and an FA mounting bracket for versatile installation.
Air enters via an M5x0.8 port, driving a Ø5 mm piston rod with an M10x1.0 rod-end thread at speeds from 50-800 mm/s. End-of-stroke energy is managed by a fixed TPU bumper at each end. Because the bumper only decelerates the final few millimeters, high-speed cycles with heavy tooling require metering the exhaust or adding an external shock absorber.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 75 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 PB12X75CBFA Is Used
PCB Depaneling Router
Clamps small daughter boards during routing operations, utilizing the CB clevis to accommodate slight pivoting as the fixture closes.
Blister Pack Sealing
Pushes the upper heat platen down onto formed plastic cavities, where the lightweight pen-size body prevents excessive inertia during fast cycling.
Sorting Diverter Gate
Actuates a lightweight flap to route small pharmaceutical bottles off a main belt, taking advantage of the FA bracket for rigid side mounting.
Is the Airtac PB Pen-type Cylinder PB12X75CBFA the Right Cylinder?
When sizing this 12 mm bore actuator, stepping down to the Ø10 bore yields 39.3 N of push at 0.5 MPa, while stepping up to the Ø16 bore provides 100.5 N.
Confirm your ordering essentials: 12 mm bore, 75 mm stroke, M5x0.8 port, no sensor magnet, CB double clevis back cover, and FA mounting bracket. Note that a plain PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift. If your application must hold a load without live pressure, specify an external stop or rod lock.
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 PB12X75CBFA FAQ
At 0.5 MPa this cylinder provides 56.5 N push and 46.7 N pull. At the maximum operating pressure of 0.7 MPa, it provides 79.1 N push and 65.4 N pull. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke ends; they do not act as a lock. For fail-safe vertical holding, you must add an external stop or a separate rod lock.
