Airtac PB Pen-type Cylinder PB10X25CB
The AirTAC Airtac PB Pen-type Cylinder PB10X25CB is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 25mm 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 PB10X25CB
The AirTAC PB10X25CB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. It delivers 39.3 N of push force and 33 N of pull force at 0.5 MPa, utilizing a 10 mm bore and a 25 mm stroke. The slim SUS304 stainless steel barrel and piston rod provide reliable durability in damp or mildly corrosive environments while keeping end-of-arm tooling extremely light.
Air enters via an M5x0.8 port, and the rod-end features an M8x1.0 thread for secure load coupling. This specific configuration includes a CB double clevis back cover, allowing the body to pivot smoothly on articulated mounts. Travel speed reaches 50-800 mm/s, with a fixed TPU bumper at each end decelerating the piston near the stroke limits.

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 PB10X25CB Is Used
PCB Pick-and-Place
Drives a small vacuum gripper on a pick-and-place head to lift electronic components, utilizing the 2 kg safe vertical lift capacity and lightweight pen-size body.
Pouch Flap Folding
Extends a thin folding arm to tuck packaging flaps on a high-speed form-fill-seal machine, pivoting smoothly via the CB double clevis to accommodate web weave.
Lab Sample Diverting
Actuates a miniature diverter gate to sort vials in clinical analyzers, where the SUS304 build withstands frequent wipe-downs and mildly humid conditions.
Is the Airtac PB Pen-type Cylinder PB10X25CB the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 24 N, which represents roughly 60% of the 39.3 N theoretical push at 0.5 MPa to account for seal friction. If your application requires lifting mass vertically, this equates to lifting about 2 kg safely with a 2:1 margin. If you need less force, the neighboring Ø6 bore provides 14.2 N push at 0.5 MPa; stepping up to the Ø12 bore yields 56.5 N push at 0.5 MPa. Confirm your ordering essentials: 10 mm bore, 25 mm stroke, M5x0.8 port, CB double clevis back cover, and no sensor magnet.
Because the Ø4 mm rod is designed purely for coaxial thrust, you should add an external guide or linear bearing if the load imposes any side load. Note that a plain PB-type cylinder does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the bumper only decelerates near the end of travel; install an external rod lock 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 PB10X25CB 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 proof pressure of 1.2 MPa, and the speed range is 50-800 mm/s.
The CB designation indicates a double clevis back cover, which allows the cylinder body to pivot freely during operation to accommodate angular misalignment. Instead of an adjustable air cushion, the cylinder uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters of travel, which may require metering out the exhaust or adding an external shock absorber if moving heavy tooling at high speeds.
