Airtac PB Pen-type Cylinder PB10X125CB
The AirTAC PB Pen-type Cylinder PB10X125CB 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 PB10X125CB
The AirTAC PB10X125CB is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency motion. It features a SUS304 stainless steel piston rod and barrel, offering reliable durability in damp or mildly corrosive environments without adding unnecessary bulk. Delivering 39.3 N of push force at 0.5 MPa, this model is driven through M5x0.8 ports and features an M8x1.0 rod-end thread for secure load coupling.
This specific configuration includes a CB double clevis back cover, allowing the cylinder to pivot smoothly on a pin mount. Because the stroke extends to 125 mm on a slender Ø4 mm rod, maintaining coaxial alignment is critical to prevent side-loading wear. The body uses fixed TPU bumpers at both ends to decelerate the piston, which is not a locking mechanism—if air pressure is lost, the rod will drift.

| 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 |

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 PB10X125CB Is Used
PCB Depaneling Routing
Pivots a light router head on a CB clevis pin to separate printed circuit boards, utilizing the 125 mm stroke to clear the work area while the SUS304 barrel resists flux humidity.
Pouch Forming Arm
Actuates a lightweight sealing jaw on a vertical form-fill machine, where the pen-size profile fits between narrow film rollers and the 39.3 N push at 0.5 MPa provides adequate clamping pressure.
Sorter Diverter Flap
Swings a small deflector gate to route small pharmaceutical vials along a secondary belt, relying on the double-acting action for rapid, repeatable 125 mm extensions.
Is the Airtac PB Pen-type Cylinder PB10X125CB the Right Cylinder?
If you need less force, stepping down to the Ø6 bore provides 14.2 N of push at 0.5 MPa; if your jig requires more thrust, stepping up to the Ø12 bore yields 56.5 N.
To finalize your order, confirm the 10 mm bore, 125 mm stroke, M5x0.8 porting, and the CB double clevis bracket. Note that this unit lacks a sensor magnet, so position detection is not possible without external switches. Furthermore, the fixed TPU bumper only absorbs impact over the final few millimeters of travel—at high cycling speeds with real tooling mass, you should meter-out the exhaust or install an external shock absorber to prevent bottoming out.
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 PB10X125CB FAQ
This double-acting cylinder generates a push force of 39.3 N and a pull force of 33 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the push force is 55 N and the pull force is 46.2 N. It operates on filtered air between 0.15-0.7 MPa, with a speed range of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
No, a plain PB-type cylinder does not hold its position or load when air is lost or the valve is centered, as the piston will drift. The fixed TPU bumpers at each end only decelerate the rod near the stroke limits and do not act as a brake. For fail-safe vertical holding, an external stop or rod lock is required.
