Airtac PB Pen-type Cylinder PB12X80U
The AirTAC Airtac PB Pen-type Cylinder PB12X80U is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 80mm 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 PB12X80U
The AirTAC PB12X80U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 12mm bore and an 80mm stroke, generating a theoretical push of 56.5 N and pull of 46.7 N at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide reliable corrosion resistance in damp or mildly wet environments, keeping weight low for end-of-arm tooling.
This specific configuration includes a U-type back cover that introduces air via a 90-degree perpendicular port, enabling flat plumbing where axial inlets would protrude. The unit ports through M5x0.8 threads and uses a fixed TPU bumper at each end to decelerate the stroke. Because the bumper is rigid, high-speed cycling with heavy tooling requires metering out the exhaust or adding an external shock absorber.

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 PB12X80U Is Used
PCB Depaneling Router
Advances a cutting tool along an 80mm path to singulate circuit boards, utilizing the flat U-type inlet to keep pneumatic hoses flush against the moving gantry.
Blister Pack Sealing
Cycles a heated platen down onto plastic cavities, where the fixed TPU bumpers absorb the end-of-stroke impact during rapid high-frequency packaging runs.
Lab Tube Elevation
Pushes a thin rack upward to present sample vials to a scanner, lifting roughly 2.9 kg safely while the SUS304 body resists humid laboratory conditions.
Is the Airtac PB Pen-type Cylinder PB12X80U the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 34 N (about 60 percent of the 56.5 N push at 0.5 MPa) to account for seal friction. If your vertical lift application needs a 2:1 safety margin, this model can raise approximately 2.9 kg. If you need slightly less force, stepping down to the 10mm bore yields 39.3 N of push at 0.5 MPa; stepping up to the 16mm bore provides 100.5 N. Note that a plain PB body does not hold position if air pressure drops or the valve centers—the piston drifts, so external stops are required for fail-safe holding.
To order, confirm the 12mm bore, 80mm stroke, M5x0.8 port, and the U-type 90-degree side inlet. This unit ships without a sensor magnet; if position feedback is needed, select an S-suffix variant. The 5mm rod uses an M10x1.0 end thread for load coupling.
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 PB12X80U 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 is 79.1 N and the pull is 65.4 N. The cylinder operates on filtered air at 0.15-0.7 MPa, travels at 50-800 mm/s, and functions in temperatures from -20 to +70 C.
No, a plain PB cylinder drifts when air is lost or the valve is centered, as the fixed TPU bumper only decelerates the last few millimeters of travel rather than locking the rod. To maintain a vertical position safely, you must install an external rod lock or mechanical stop.
