Airtac PB Pen-type Cylinder PB12X10CB
The AirTAC Airtac PB Pen-type Cylinder PB12X10CB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 10mm 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 PB12X10CB
The AirTAC PB12X10CB is a JIS pen-size double-acting single-rod mini cylinder engineered for short, high-frequency motion. It delivers 56.5 N of push and 46.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless barrel and a 5 mm rod to keep end-of-arm tooling weight down in compact jigs. Air connects via an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling.
This variant includes a CB double clevis back cover, allowing the body to pivot smoothly on articulated mounts. Travel is capped by a fixed TPU bumper at each end rather than an adjustable air cushion, meaning it decelerates only over the final few millimeters. For rapid cycling with heavy tooling, metering out the exhaust or adding an external shock absorber prevents the bumper from bottoming out.

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 PB12X10CB Is Used
PCB Depaneling Jig
Provides the short 10 mm thrust stroke needed to snap pre-scored circuit boards apart within a dense, tight-clearance routing fixture.
Pouch Sealing Clamp
Pivots via the CB clevis to apply rapid 56.5 N clamping force on flexible packaging material moving through a high-speed horizontal flow wrapper.
Diverter Gate Actuation
Drives a small mechanical flap on a conveyor sorting line, relying on the stainless build to withstand mildly humid washdown environments.
Is the Airtac PB Pen-type Cylinder PB12X10CB the Right Cylinder?
If your application demands less force, stepping down to the Ø10 bore yields 39.3 N of push at 0.5 MPa; conversely, the Ø16 bore provides 100.5 N if you need greater thrust.
Because this is a double-acting cylinder, the piston will drift and fail to hold its position if air pressure drops or the valve is centered—the fixed bumper decelerates impact near stroke end but acts as neither a lock nor a brake. To secure a suspended load without live pressure, integrate an external rod lock. When ordering, confirm the 10 mm stroke, M5x0.8 porting, the CB double clevis inlet, and whether you need mounting brackets like LB, FA, or CJ.
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 PB12X10CB FAQ
At 0.5 MPa, this 12 mm bore cylinder outputs 56.5 N of push (extend) and 46.7 N of pull (retract). At the maximum operating pressure of 0.7 MPa, those figures rise to 79.1 N push and 65.4 N pull. It operates between 0.15 and 0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
No, a standard double-acting PB cylinder will drift if air is lost or the valve is centered. The fixed TPU bumpers at each end only decelerate the piston near the stroke limits; they do not function as a locking brake. If your pivoting CB clevis mount requires fail-safe position holding, you must add an external stop or rod lock.
