Airtac PB Pen-type Cylinder PB12X150SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X150SCB 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 PB12X150SCB
The AirTAC PB12X150SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a SUS304 stainless steel piston rod and slim round barrel, providing excellent durability in damp or mildly corrosive workspaces. Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore unit is ported via M5x0.8 and utilizes a 5 mm rod with an M10x1.0 rod-end thread.
This specific configuration includes a built-in piston magnet (-S) for position sensing using AirTAC reed or electronic switches, alongside a CB double clevis back cover that accommodates pivoting loads. The unit relies on a fixed TPU bumper at each end to decelerate the stroke, and its 150 mm travel stays within the 200 mm standard limit for this bore size.

| 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 |

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 PB12X150SCB Is Used
PCB Depaneling Router
Actuates a pivoting cutting head on an electronic depaneling machine, utilizing the CB clevis to maintain alignment while routing small circuit boards.
Pouch Sealing Clamp
Cycles a lightweight sealing jaw on a vertical form-fill-seal line, where the 150 mm stroke provides ample reach to clear packaging film during product drops.
Lab Sample Dispenser
Drives a pipetting arm in a wet laboratory environment, benefiting from the SUS304 stainless construction to resist mild chemical corrosion.
Is the Airtac PB Pen-type Cylinder PB12X150SCB the Right Cylinder?
If you need less force, the adjacent Ø10 bore provides 39.3 N of push at 0.5 MPa; stepping up to the Ø16 bore yields 100.5 N. Because the slender 5 mm rod is designed strictly for coaxial thrust, adding an external guide or linear bearing is recommended over this 150 mm stroke to prevent side-loading damage.
To confirm your ordering essentials: specify the 12 mm bore, 150 mm stroke, M5x0.8 port, -S magnet for sensing, and the CB double clevis mount. Note that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered—the piston will drift, and the fixed bumper only decelerates near the stroke end, 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 PB12X150SCB 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 operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
No, Ø6-Ø16 models use a fixed TPU bumper at each end that only decelerates the last few millimeters of travel. It is not field-adjustable, so at higher speeds with real tooling mass you should meter-out the exhaust or fit an external shock absorber.
