Airtac PB Pen-type Cylinder PB12X180SU
The AirTAC Airtac PB Pen-type Cylinder PB12X180SU 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 PB12X180SU
The AirTAC PB12X180SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, it utilizes an M5x0.8 air port and an M10x1.0 rod-end thread for secure load coupling.
This specific configuration includes a built-in piston magnet (S) for position detection and a U-type back cover providing a 90-degree perpendicular air inlet for flat plumbing. Travel is controlled by a fixed TPU bumper at each end that decelerates the piston near the stroke limits. Because the rod is a slender Ø5 mm, maintaining coaxial thrust over the 180 mm stroke is critical to prevent side-loading wear.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 180 mm |
| 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 |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 300 mm |
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 PB12X180SU Is Used
PCB Edge Guiding
Positions delicate circuit boards on an SMT line using the 90-degree side inlet to keep pneumatic plumbing flat against the machine frame.
Film Roll Tensioning
Applies steady coaxial thrust on a packaging web guide, where the stainless barrel resists humid factory conditions and the magnet tracks travel.
Is the Airtac PB Pen-type Cylinder PB12X180SU the Right Cylinder?
When sizing this 12 mm bore actuator, consider stepping down to the Ø10 bore if your payload is lighter, which yields 39.3 N of push at 0.5 MPa. If your application demands more thrust, stepping up to the Ø16 bore provides 100.5 N at the same pressure.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the bumpers only decelerate near stroke end rather than locking the rod. If your process requires fail-safe load holding, an external stop or rod lock must be fitted. Confirm your ordering essentials: 12 mm bore, 180 mm stroke, M5x0.8 port, S magnet, U 90-degree side inlet, and your preferred mounting bracket.
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 PB12X180SU 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.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumpers only decelerate the rod near the end of travel and do not act as a brake. For vertical loads, you should add an external rod lock or mechanical stop.
