Airtac PB Pen-type Cylinder PB12X80SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X80SCB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 80mm 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 PB12X80SCB
The AirTAC PB12X80SCB is a double-acting JIS pen-size mini cylinder engineered for high-frequency small-part motion. It provides 56.5 N of push and 46.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a Ø5 mm piston rod. The CB suffix equips the rear with a double clevis for pivoting loads, while the integrated S magnet enables position detection.
Air enters via an M5x0.8 port, driving the piston at speeds between 50 and 800 mm/s. Instead of an adjustable air cushion, the ends feature a fixed TPU bumper that decelerates travel over the final few millimeters. Because the rod is only 5 mm thick, it is built for coaxial thrust; over the 80 mm stroke, adding an external guide prevents deflection under off-axis loads.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 80 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 PB12X80SCB Is Used
PCB Depanelling Arms
Actuates a pivoting routing head on an electronics assembly line, using the CB clevis to maintain alignment while separating printed circuit boards with precise 56.5 N thrust.
Pouch Flap Folding
Swings a lightweight guide arm to tuck carton flaps on a packaging conveyor, where the integrated S magnet confirms the fold position for the gluing station.
Component Sorting Gates
Drives a diverter gate in a small-parts sorting chute, relying on the fixed TPU bumper to absorb the impact of rapid 80 mm strokes at high cycling frequencies.
Is the Airtac PB Pen-type Cylinder PB12X80SCB the Right Cylinder?
If your application requires less force, the Ø10 bore variant offers 39.3 N of push at 0.5 MPa, whereas stepping up to the Ø16 bore yields 100.5 N for heavier tooling.
Confirm the ordering essentials match your assembly: 12 mm bore, 80 mm stroke, M5x0.8 ports, S magnet for reed or electronic switches, and the CB double clevis mount. Note that a standard PB body does not hold position if air pressure drops; the piston will drift, so an external rod lock is necessary for fail-safe holding.
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 PB12X80SCB FAQ
At 0.5 MPa, the push force is 56.5 N and the pull force is 46.7 N. At the maximum operating pressure of 0.7 MPa, the push force is 79.1 N and the pull force is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
The CB suffix indicates a rear double clevis that allows the cylinder to pivot during operation. Impact at the stroke ends is managed by a fixed TPU bumper, not an adjustable air cushion; for heavy tooling at high speeds, metering out the exhaust or adding an external shock absorber is recommended.
