Airtac PB Pen-type Cylinder PB10X55CB
The AirTAC Airtac PB Pen-type Cylinder PB10X55CB is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 55mm 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 PB10X55CB
The AirTAC PB10X55CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and a 4 mm piston rod, delivering 39.3 N of push force at 0.5 MPa. The CB double clevis back cover is built directly into the rear cover, providing an integrated pivot point for swinging or articulated loads. Air connects via an M5x0.8 port, and the rod end utilizes an M8x1.0 thread for secure load coupling.
Because the 4 mm rod is designed strictly for coaxial thrust, you should add an external linear bearing if the application involves any off-axis loading. This model relies on a fixed TPU bumper at each end to decelerate the stroke over the final few millimeters. Since this bumper is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving real tooling mass at higher speeds.

| 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 PB10X55CB Is Used
PCB Routing Pivot
Swings a lightweight routing fixture via the CB clevis to angle small circuit boards for selective soldering, utilizing the 39.3 N push within a tight electronics assembly cell.
Pouch Flap Folder
Articulates a slim folding blade to tuck packaging flaps on a compact vertical form-fill machine, taking advantage of the 50-800 mm/s speed range without adding bulk.
Small Part Diverter
Pivots a deflector gate on a conveyor line to sort lightweight plastic caps, where the SUS304 barrel withstands mildly washdown environments.
Is the Airtac PB Pen-type Cylinder PB10X55CB the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 24 N, which is roughly 60 percent of the 39.3 N theoretical push at 0.5 MPa, ensuring smooth travel against seal friction. In vertical lift terms, 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 of push at 0.5 MPa; stepping up to the Ø12 bore yields 56.5 N. Remember that a plain PB body 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 stroke end. For a fail-safe hold, specify an external rod lock. To order, confirm the 10 mm bore, 55 mm stroke, M5x0.8 port, CB double clevis, and no magnet.
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 PB10X55CB FAQ
This double-acting cylinder generates 39.3 N push and 33 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it produces 55 N push and 46.2 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The CB designation means the rear cover features a double clevis for pivoting articulation. End-of-stroke deceleration is handled by a fixed TPU bumper at each end, which is not field-adjustable. For high-energy pivoting mass, you should meter-out the exhaust or add an external shock absorber, as the bumper only cushions the last few millimeters.
