Airtac PB Pen-type Cylinder PB12X100U
The AirTAC Airtac PB Pen-type Cylinder PB12X100U is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 100mm 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 PB12X100U
The AirTAC PB12X100U is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It generates 56.5 N of push and 46.7 N of pull at 0.5 MPa, utilizing a 12 mm bore and a 100 mm stroke. The SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments, while the slim profile saves payload on end-of-arm tooling.
This variant features a U-type back cover, providing a 90-degree perpendicular air inlet for flat plumbing in confined spaces. Air connects via an M5x0.8 port, and the M10x1.0 rod-end thread secures the load. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion.

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 PB12X100U Is Used
PCB Depaneling Router
Advances a guide pin on an electronic board depaneling fixture, where the 100 mm stroke and 56.5 N push provide ample thrust without stressing delicate substrates.
Carton Flap Folder
Tucks minor flaps on a small carton erecting line; the U-type 90-degree inlet keeps pneumatic plumbing flush against the machine frame to save clearance.
Lab Dispenser Positioning
Moves a pipette head over a microplate tray in a wet analytical station, benefiting from the SUS304 stainless construction against reagent splashes.
Is the Airtac PB Pen-type Cylinder PB12X100U the Right Cylinder?
When sizing this 12 mm bore actuator, stepping down to the 10 mm variant yields 39.3 N of push at 0.5 MPa, while stepping up to the 16 mm bore provides 100.5 N. This PB12X100U configuration includes a standard 100 mm stroke, an M5x0.8 port, and a U-type 90-degree side inlet. It ships without a sensor magnet; add the -S suffix if position feedback is required.
Because the fixed TPU bumper only decelerates the piston over the final few millimeters, metering out the exhaust or adding an external shock absorber is advised when cycling real tooling mass at high speeds. Furthermore, a plain PB body does not hold its position if air pressure drops or the valve centers—the piston will drift. An external stop or rod lock is necessary for fail-safe load holding.
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 PB12X100U 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 and a proof pressure of 1.2 MPa.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumper at each end only decelerates the rod near the stroke ends; it does not act as a brake. For vertical or fail-safe holding, an external rod lock or mechanical stop is required.
