Airtac PB Pen-type Cylinder PB12X180U
The AirTAC Airtac PB Pen-type Cylinder PB12X180U is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 180mm 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 PB12X180U
The AirTAC PB12X180U is a JIS pen-size double-acting single-rod mini cylinder, delivering 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. Its slim SUS304 stainless steel round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments, while keeping weight low for end-of-arm tooling. This specific configuration features a 180 mm stroke and a U-type back cover, which provides a 90-degree perpendicular air inlet for flat plumbing in confined spaces.
Air enters via an M5x0.8 port, driving the Ø5 mm piston rod with an M10x1.0 rod-end thread at speeds from 50 to 800 mm/s. Operating pressure ranges from 0.15 to 0.7 MPa. Instead of an adjustable air cushion, the ends rely on a fixed TPU bumper to decelerate the piston over the final few millimeters. Because this unit lacks the -S magnet option, it cannot directly mount AirTAC position switches.

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 PB12X180U Is Used
PCB Depaneling Router
Extends a light cutting tool guide over a 180 mm travel path on an electronics assembly line, utilizing the U-type side inlet to keep pneumatic tubing flush against the machine frame.
Package Flap Folder
Pushes corrugated carton flaps into position on a packaging conveyor, where the fixed TPU bumper absorbs the repeated impact of high-speed cycling.
Lab Sample Dispenser
Moves a pipette array across a testing station, with the SUS304 stainless barrel resisting humidity and chemical splashes typical in laboratory environments.
Is the Airtac PB Pen-type Cylinder PB12X180U the Right Cylinder?
If you need less force, the adjacent Ø10 bore provides 39.3 N of push at 0.5 MPa; stepping up to the Ø16 bore yields 100.5 N. Note that a plain PB body does not hold its position if air pressure drops or the valve is centered—the piston will drift, so an external rod lock or mechanical stop is required for fail-safe holding.
Confirm these ordering essentials before requesting a quote: 12 mm bore, 180 mm stroke, M5x0.8 port, no sensor magnet, U-type 90-degree side inlet, and no mounting bracket. Given the 180 mm stroke combined with the slender Ø5 mm rod, always ensure the load is guided by an external linear bearing to prevent side-loading and buckling, as the rod is designed purely for coaxial thrust.
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 PB12X180U 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 cylinder operates between 0.15 and 0.7 MPa, with a speed range of 50-800 mm/s and a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not an adjustable air cushion. If you are moving real tooling mass at high speeds, you should meter-out the exhaust or add an external shock absorber. Additionally, it does not hold its load if air is lost—the piston will drift, requiring an external stop for fail-safe positioning.
