Airtac PB Pen-type Cylinder PB10X55U
The AirTAC Airtac PB Pen-type Cylinder PB10X55U 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 PB10X55U
The AirTAC PB10X55U is a JIS double-acting pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering reliable durability in damp or mildly corrosive work areas. Generating 39.3 N of push force at 0.5 MPa, this 10 mm bore unit uses an M5x0.8 port and a 4 mm rod with an M8x1.0 rod-end thread. The U suffix designates a 90-degree perpendicular side air inlet, allowing flat plumbing in confined spaces.
This model relies on a fixed TPU bumper at each end to decelerate the piston over the final few millimeters of travel. Because the bumper is not adjustable, high-speed cycles with real tooling mass may require metering out the exhaust or adding an external shock absorber. The slim round body saves payload on end-of-arm tooling where larger actuators cannot fit. Plan for a safe working load of roughly 24 N (about 60 percent of the 0.5 MPa rating), which equates to lifting around 2 kg vertically with a sane 2:1 margin.

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 PB10X55U Is Used
PCB Depaneling Jig
Actuates a small cutting blade on a tight electronics assembly line where the slim stainless body resists flux fumes and the U inlet keeps plumbing flat against the gantry.
Carton Flap Folder
Tucks small corrugated flaps at high speed, relying on the fixed TPU bumper to soften the end-of-stroke impact while fitting within narrow conveyor side frames.
Lab Dispenser Valve
Precisely pushes a metered volume of reagent, lifting a 1.5 kg fluid cartridge vertically using the 39.3 N extension force at 0.5 MPa.
Is the Airtac PB Pen-type Cylinder PB10X55U the Right Cylinder?
When sizing this actuator, consider stepping down to the 6 mm bore if your payload is very light, which provides 14.2 N of push at 0.5 MPa. If you need more thrust, the 12 mm bore offers 56.5 N at the same pressure. For the PB10X55U specifically, confirm your ordering essentials: 10 mm bore, 55 mm stroke, M5x0.8 porting, no sensor magnet, and the U-type 90-degree side inlet. The 4 mm rod is built for coaxial thrust, so over this 55 mm stroke you should add an external linear bearing if the load exerts any off-axis pressure.
A standard PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift. If your process demands fail-safe load holding without live pressure, you must integrate an external stop or a dedicated rod lock.
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 PB10X55U FAQ
At 0.5 MPa this 10 mm bore cylinder provides 39.3 N of push (extend) and 33 N of pull (retract). At the maximum operating pressure of 0.7 MPa, the push is 55 N and the pull is 46.2 N. It operates on filtered air at 0.15-0.7 MPa, runs at 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The U suffix indicates a 90-degree perpendicular side air inlet, which allows hoses to route flat against a machine frame rather than sticking out axially. Impact control is handled by a fixed TPU bumper at each end that decelerates the piston near the stroke limits; it is not adjustable, so for heavy high-speed loads you should meter-out the exhaust or add an external shock absorber.
