Airtac PB Pen-type Cylinder PB12X150R
The AirTAC Airtac PB Pen-type Cylinder PB12X150R 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 PB12X150R
The AirTAC PB12X150R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 12mm bore and 150mm stroke, generating 56.5 N of push force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide reliable durability in damp or mildly corrosive environments without adding excessive bulk to your assembly.
This configuration uses an R axial air inlet for straightforward in-line plumbing and connects via an M5x0.8 port. Because it lacks a sensor magnet, position detection is not supported on this specific unit. The cylinder relies on a fixed TPU bumper at each end to decelerate the piston over its final few millimeters of travel.

| Rod diameter | Ø5 mm |
| Stroke | 150 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) |

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 PB12X150R Is Used
PCB Depaneling Router
Pushes a small carrier fixture along a linear rail to feed uncut circuit boards into a routing spindle, utilizing the 56.5 N extend force within a compact electronics assembly cell.
Carton Flap Folder
Tucks minor product flaps prior to case sealing on a compact packaging line, where the slim 12mm barrel fits neatly between adjacent conveyor guides.
Lab Sample Dispenser
Actuates a small dosing valve to release reagents into test trays, benefiting from the SUS304 construction in environments wiped down with mild cleaning agents.
Is the Airtac PB Pen-type Cylinder PB12X150R the Right Cylinder?
When sizing this 12mm bore unit, consider stepping down to the 10mm bore if your application requires less force (39.3 N push at 0.5 MPa), or moving up to the 16mm bore for heavier payloads (100.5 N push at 0.5 MPa).
Keep in mind that a plain PB cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, so an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 12mm bore, 150mm stroke, M5x0.8 port, no magnet, R axial inlet, and no mounting bracket. Additionally, the 5mm rod is built for coaxial thrust, so over this 150mm stroke you should add an external linear bearing to prevent side-load damage.
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 PB12X150R 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.
It uses a fixed TPU bumper at each end that decelerates the piston over the final few millimeters; it is not adjustable and not a lock. If driving real tooling mass at high speed, meter-out the exhaust or add an external shock absorber. If air is lost, the piston will drift, so an external stop is needed to hold a load.
