Airtac PB Pen-type Cylinder PB12X30CB
The AirTAC Airtac PB Pen-type Cylinder PB12X30CB 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 PB12X30CB
The AirTAC PB12X30CB is a JIS double-acting pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a SUS304 stainless steel piston rod and barrel, offering reliable durability in damp or mildly corrosive environments without adding bulk. Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore unit is both small and fast.
This specific configuration includes a CB double clevis back cover, allowing the cylinder to pivot smoothly on an anchoring pin to accommodate lateral load movement during the stroke. Air plumbing connects via an M5x0.8 port, and the Ø5 mm rod terminates in an M10x1.0 thread for secure load coupling. Deceleration is handled by a fixed TPU bumper at each end, which absorbs impact over the final few millimeters of travel.

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 PB12X30CB Is Used
PCB Depanelling Pivot
Actuates a pivoting cutting blade on an electronics assembly line, utilizing the CB clevis to swing the shear mechanism accurately through 30 mm of travel.
Pouch Forming Jaw
Drives the sealing jaw on a vertical form-fill-seal machine, where the compact stainless body withstands washdown cycles and fits within the narrow packaging head.
Sorter Diverter Arm
Pushes lightweight cartons at a logistics routing station, relying on the fixed TPU bumpers to absorb the repetitive impact of high-speed routing operations.
Is the Airtac PB Pen-type Cylinder PB12X30CB the Right Cylinder?
If you need to step down, the Ø10 bore provides 39.3 N of push at 0.5 MPa, while stepping up to the Ø16 bore yields 100.5 N, letting you tune the force precisely to your fixture. Because the Ø5 mm rod is designed strictly for coaxial thrust, avoid side loading and add an external guide if your tooling hangs off-axis. Remember that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, so fit an external rod lock if your mechanism must hold a load safely in place. Confirm your ordering essentials: 12 mm bore, 30 mm stroke, M5x0.8 port, CB double clevis, and no sensor magnet.
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 PB12X30CB 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 of 50-800 mm/s.
The CB back cover is a double clevis design that allows the cylinder body to pivot, which is ideal for mechanisms requiring angular movement during the stroke. Instead of an adjustable air cushion, it uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters. If you are moving heavy tooling at high speeds, you should meter-out the exhaust or add an external shock absorber to prevent bottoming out.
