Airtac PB Pen-type Cylinder PB10X120U
The AirTAC Airtac PB Pen-type Cylinder PB10X120U 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 PB10X120U
The AirTAC PB10X120U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 39.3 N of push and 33 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to endure mildly corrosive or damp environments. This model features a U-type back cover, providing a 90-degree side air inlet for flat plumbing in confined spaces.
Equipped with a fixed TPU bumper at each end, impact is decelerated over the final few millimeters of travel. The M5x0.8 port and M8x1.0 rod-end thread simplify integration into existing pneumatic setups. Because the rod is a slender 4 mm diameter, maintaining coaxial alignment is critical over the 120 mm stroke to prevent side-loading damage.

| 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 PB10X120U Is Used
PCB Depaneling Router
Pushes a lightweight tooling pin to secure circuit boards during routing, utilizing the 90-degree side inlet to keep pneumatic hoses flat against the machine frame.
Package Sorting Diverter
Extends 120 mm to deflect small cartons on a conveyor belt, relying on the fixed TPU bumper to soften the impact at the end of each rapid cycle.
Lab Sample Dispenser
Moves a pipette head across a testing station, where the SUS304 stainless build resists moisture and the slim body saves valuable space on the bench.
Is the Airtac PB Pen-type Cylinder PB10X120U the Right Cylinder?
If you need less force, stepping down to the Ø6 bore yields 14.2 N of push at 0.5 MPa, while stepping up to the Ø12 bore provides 56.5 N.
Remember that a plain cylinder drifts when air is lost or the valve is centered, so an external stop or rod lock is required for fail-safe holding. To order, confirm the 10 mm bore, 120 mm stroke, M5x0.8 port, no magnet, and the U 90-degree side inlet configuration.
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 PB10X120U FAQ
At 0.5 MPa, the push force is 39.3 N and the pull force is 33 N. At the maximum operating pressure of 0.7 MPa, the push force is 55 N and the pull force is 46.2 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end and does not act as a lock. For vertical loads, you must add an external rod lock or mechanical stop.
