Airtac PB Pen-type Cylinder PB12X40SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X40SCB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 40mm 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 PB12X40SCB
The AirTAC PB12X40SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It provides 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 steel round barrel and screwed-in covers make it inherently suitable for damp or mildly corrosive production lines, while keeping end-of-arm tooling exceptionally light.
This specific configuration includes a built-in piston magnet (S) for position detection using AirTAC reed or electronic switches, and a CB double clevis back cover that accommodates pivoting loads. End-of-stroke deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only absorbs energy over the final few millimeters, high-speed cycles with heavy tooling require metering out the exhaust or adding an external shock absorber.

| Rod diameter | Ø5 mm |
| Stroke | 40 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 |

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 PB12X40SCB Is Used
PCB Depaneling Router
Actuates a small cutting blade or clamping jaw in electronics manufacturing, utilizing the 56.5 N extend force to secure boards during routing without stressing delicate traces.
Pouch Sealing Clamp
Employs the CB double clevis to pivot a sealing arm into position on a vertical form-fill-seal machine, handling lightweight polymer films with fast 50-800 mm/s cycling.
Lab Sample Ejector
Pushes processed vials out of a centrifuge carousel using the M10x1.0 rod-end thread, where the SUS304 barrel resists humidity and chemical wipe-downs.
Is the Airtac PB Pen-type Cylinder PB12X40SCB the Right Cylinder?
When sizing this 12 mm bore actuator, stepping down to the PB10X40 yields 39.3 N of push at 0.5 MPa, whereas stepping up to the PB16X40 increases that output to 100.5 N. Confirm your ordering essentials: 12 mm bore, 40 mm stroke, M5x0.8 port, S magnet, and CB clevis. Note that a standard PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift, so a fail-safe application requires 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 PB12X40SCB 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 is 79.1 N and the pull is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa, and the speed range is 50-800 mm/s.
The S denotes a built-in piston magnet, allowing you to mount AirTAC reed or electronic solid-state switches for precise end-position detection. The CB suffix indicates a double clevis back cover, which is designed to handle pivoting loads and accommodate angular misalignment during linkage movement.
