Airtac PB Pen-type Cylinder PB10X120CB
The AirTAC PB Pen-type Cylinder PB10X120CB is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 120mm 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 PB10X120CB
The AirTAC PB10X120CB is a JIS pen-size double-acting single-rod cylinder engineered for compact automation. It generates 39.3 N of push and 33 N of pull at 0.5 MPa, utilizing a 10 mm bore and a 120 mm stroke. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping mass low for end-of-arm tooling.
This specific configuration includes a CB double clevis back cover for pivoting loads. Air connections are made via M5x0.8 ports, and the Ø4 mm piston rod features an M8x1.0 rod-end thread. Deceleration is handled by a fixed TPU bumper at each end, which absorbs impact over the final few millimeters of travel rather than acting as a locking mechanism.

| 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 |

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 (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 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 PB10X120CB Is Used
PCB Depaneling Router
Actuates a pivoting cutting head on a depaneling machine, utilizing the CB clevis to swing the blade precisely across 120 mm of travel.
Sorting Diverter Arm
Pushes small electronic packages onto a secondary belt, where the stainless build withstands factory humidity and the pen-size profile fits between conveyor rollers.
Carton Flap Folder
Folds minor flaps on small retail boxes, taking advantage of the 39.3 N push force and fixed TPU bumpers to maintain rhythm in high-speed packaging lines.
Is the Airtac PB Pen-type Cylinder PB10X120CB the Right Cylinder?
When sizing this unit, consider stepping down to the Ø6 bore if your layout permits, which yields 14.2 N of push at 0.5 MPa. If you need more muscle, the Ø12 bore provides 56.5 N at the same pressure.
Because the thin Ø4 mm rod is built for coaxial thrust, adding an external guide or linear bearing is recommended over this 120 mm stroke to prevent side-load damage. Note that a plain PB body drifts when air is lost or the valve is centered, so an external rod lock is required for fail-safe holding. To order, confirm the 10 mm bore, 120 mm stroke, M5x0.8 porting, 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 PB10X120CB FAQ
At 0.5 MPa, this double-acting cylinder provides 39.3 N of push and 33 N of pull. At the maximum operating pressure of 0.7 MPa, it yields 55 N of push and 46.2 N of pull. It operates on filtered air at 0.15-0.7 MPa, runs at speeds from 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The CB double clevis allows the cylinder to pivot with the load, ideal for articulated mechanisms. End-of-stroke energy is managed by fixed TPU bumpers that decelerate the piston over the last few millimeters. Because these bumpers are not adjustable, you should meter-out the exhaust or add an external shock absorber when cycling high tooling mass at speed.
