Airtac PB Pen-type Cylinder PB10X125R
The AirTAC PB Pen-type Cylinder PB10X125R is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 125mm 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 PB10X125R
The AirTAC PB10X125R is a double-acting JIS pen-size mini cylinder engineered for compact automation. It generates 39.3 N of push force and 33 N of pull force at 0.5 MPa, utilizing a 4 mm stainless steel piston rod with an M8x1.0 rod-end thread. The slim SUS304 round barrel saves valuable space and reduces payload on light end-of-arm tooling where larger bodies cannot fit.
This specific configuration features an R axial air inlet for in-line plumbing and uses an M5x0.8 port. Because it lacks a sensor magnet, position detection is not supported without modification. To manage impact energy, a fixed TPU bumper at each end decelerates the piston over the final few millimeters of travel.

| Rod diameter | Ø4 mm |
| Stroke | 125 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 (Ø10mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 39.3 N | 33.0 N |
| 0.7 MPa (max) | 55.0 N | 46.2 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 PB10X125R Is Used
PCB Depaneling Router
Pushes a small carrier fixture along a linear rail to position uncut circuit boards under a high-speed routing spindle, utilizing the 39.3 N extend force to overcome light slide resistance.
Blister Pack Sealing
Raises a thin aluminum heat seal head into a plastic blister card fixture, where the fixed TPU bumpers cushion the stroke end without requiring bulky external cushioning hardware.
Is the Airtac PB Pen-type Cylinder PB10X125R the Right Cylinder?
When sizing this 10 mm bore actuator, consider stepping down to the 6 mm bore (14.2 N push at 0.5 MPa) for lighter tasks, or up to the 12 mm bore (56.5 N push at 0.5 MPa) if you need more thrust. For the PB10X125R, confirm your ordering essentials: 10 mm bore, 125 mm stroke, R axial inlet, and no magnet.
Keep in mind 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. If your application requires fail-safe position holding, you must incorporate an external stop or a dedicated rod lock. Additionally, the 4 mm rod is designed strictly for coaxial thrust, so over this 125 mm stroke, add an external guide or 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 PB10X125R FAQ
At 0.5 MPa, the push force is 39.3 N and the pull force is 33 N. At the maximum operating pressure of 0.7 MPa, the push force is 55 N and the pull force is 46.2 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s and a proof pressure of 1.2 MPa.
No, a plain PB-type cylinder does not hold its load when air is lost or the valve is centered, as the piston will drift. The fixed TPU bumper only decelerates the piston near the stroke end and does not act as a brake; an external stop or rod lock is required for fail-safe holding.
