Airtac PB Pen-type Cylinder PB10X125SCB
The AirTAC Airtac PB Pen-type Cylinder PB10X125SCB 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 PB10X125SCB
The AirTAC PB10X125SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It provides a 39.3 N push and 33 N pull at 0.5 MPa, utilizing an M5x0.8 air port and an M8x1.0 rod-end thread. The SUS304 stainless barrel and piston rod resist moisture, making it suitable for damp production environments where a standard round body might corrode.
This 125 mm stroke variant includes a built-in piston magnet for AirTAC reed or electronic switches, plus a CB double clevis for pivoting mountings. Because the bore is 10 mm, it relies on a fixed TPU bumper at each end rather than an adjustable air cushion. The Ø4 mm rod is designed for coaxial thrust; over this longer stroke, adding an external guide prevents side-load wear.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø10 mm |
| 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) |
| Max standard stroke | Up to 200 mm |
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 PB10X125SCB Is Used
PCB Depanelling Pivot
Uses the CB clevis to swing a small cutting blade across routed circuit boards, relying on the 125 mm travel to clear standard panel widths.
Film Roll Tensioner
Maintains light, consistent pressure on packaging web guides via its 39.3 N push force, while the stainless body withstands washdown cycles.
Lab Sample Dispenser
Actuates a pipetting arm over a 125 mm range, where the built-in S magnet triggers solid-state switches for precise fluid metering.
Is the Airtac PB Pen-type Cylinder PB10X125SCB the Right Cylinder?
When sizing this unit, consider stepping down to the Ø6 bore for lighter duties, which yields a 14.2 N push at 0.5 MPa, or moving up to the Ø12 bore for heavier tasks with a 56.5 N push at 0.5 MPa.
Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered, as the bumpers only decelerate near stroke end rather than locking the load; install an external rod lock if you need fail-safe holding. To order, confirm the 10 mm bore, 125 mm stroke, M5x0.8 port, S magnet, and CB double clevis back cover.
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 PB10X125SCB 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 is 55 N and the pull is 46.2 N. The cylinder operates at 0.15-0.7 MPa with a speed range of 50-800 mm/s.
The CB suffix denotes a double clevis back cover, allowing the cylinder to pivot on a pin to accommodate load arc motion. End-of-stroke deceleration is handled by fixed TPU bumpers rather than adjustable air cushions; for high-speed tooling mass, meter-out the exhaust or add an external shock absorber.
