Airtac PB Pen-type Cylinder PB12X150SU
The AirTAC Airtac PB Pen-type Cylinder PB12X150SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 150mm 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 PB12X150SU
The AirTAC PB12X150SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 12 mm bore and a 150 mm stroke, generating 56.5 N of push and 46.7 N of pull at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments, while the lightweight body is ideal for end-of-arm tooling where space is tight.
This configuration includes a built-in piston magnet (-S) for position sensing with AirTAC reed or electronic switches, and a U-type back cover offering a 90-degree side air inlet for flat plumbing. The M5x0.8 port and M10x1.0 rod-end thread simplify integration. Operating pressure ranges from 0.15 to 0.7 MPa, and fixed TPU bumpers at both ends absorb impact at the stroke limits.

| 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 (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 PB12X150SU Is Used
PCB Depaneling Router
Drives a lightweight cutting head along a 150 mm path to singulate printed circuit boards, utilizing the slim stainless body to fit within dense electronics manufacturing fixtures.
Carton Flap Folder
Extends 150 mm to fold minor flaps on small packaging lines, where the 56.5 N push force easily overcomes light cardboard resistance and the U inlet keeps plumbing flat against the frame.
Lab Sample Dispenser
Actuates a pipette mechanism for liquid handling in wet lab environments, relying on the SUS304 construction to resist mild chemical exposure during high-speed 50-800 mm/s cycles.
Is the Airtac PB Pen-type Cylinder PB12X150SU the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø10 bore (39.3 N push at 0.5 MPa) for lighter loads, or up to the Ø16 bore (100.5 N push at 0.5 MPa) if you need more thrust. Confirm your ordering essentials: 12 mm bore, 150 mm stroke, M5x0.8 port, -S magnet, and U side inlet. Note that a plain PB body does not hold its load if air pressure is lost; the piston will drift, so an external rod lock is required for fail-safe 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 PB12X150SU 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 proof pressure of 1.2 MPa.
No, a plain PB cylinder drifts if air is lost or the valve is centered; an external rod lock is needed for fail-safe holding. Additionally, the fixed TPU bumpers only decelerate the last few millimeters of travel. At high speeds with real tooling mass, you should meter-out the exhaust or add an external shock absorber, and guide the thin Ø5 mm rod to prevent side load.
