Airtac PB Pen-type Cylinder PB10X45U
The AirTAC Airtac PB Pen-type Cylinder PB10X45U is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 45mm 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 PB10X45U
The AirTAC PB10X45U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 39.3 N of push force and 33 N of pull force at 0.5 MPa, utilizing a 10 mm bore and a 45 mm stroke. The slim SUS304 stainless steel barrel and piston rod provide excellent durability in damp or mildly corrosive environments, while keeping weight to a minimum for light end-of-arm tooling.
This specific configuration includes a U-type back cover, providing a 90-degree perpendicular air inlet for flat plumbing in tight spaces. The Ø6-Ø16 bore range incorporates a fixed TPU bumper at each end to decelerate the piston near stroke end, though it is not an adjustable air cushion. Air connections use an M5x0.8 port, and the rod-end features an M8x1.0 thread for secure load coupling.

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 PB10X45U Is Used
PCB Pick-and-Place
Drives small vacuum grippers in electronics assembly lines, utilizing its lightweight stainless body to minimize inertia on high-speed robotic arms.
Blister Pack Sealing
Actuates small sealing jaws or product pushers in pharmaceutical packaging equipment, where the 90-degree side inlet keeps plumbing flat against the machine frame.
Lab Dispenser Actuation
Moves precision metering valves for reagent dispensing, benefiting from the smooth 50-800 mm/s speed range and fixed TPU bumpers to prevent end-of-stroke impact.
Is the Airtac PB Pen-type Cylinder PB10X45U the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 24 N (roughly 60% of the 39.3 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. In vertical lift terms, this equates to lifting about 2 kg safely with a 2:1 margin. If you need less force, stepping down to the Ø6 bore yields 14.2 N push at 0.5 MPa; stepping up to the Ø12 bore provides 56.5 N. Keep in mind the thin Ø4 mm piston rod is built for coaxial thrust, so over long strokes or off-axis loads, adding an external guide or linear bearing prevents side-load damage.
A plain PB-type cylinder does not hold its position if air pressure is lost or the valve is centered—the piston will drift, and the bumper only decelerates it near the stroke end, acting as neither a lock nor a brake. For fail-safe holding, an external stop or rod lock is required. To order, confirm the 10 mm bore, 45 mm stroke, M5x0.8 port, U-type 90-degree side inlet, 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 PB10X45U 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 operational speed ranges from 50 to 800 mm/s.
No, a plain PB-type cylinder does not hold its load or position when air is lost or the valve is centered. The piston will drift, and the fixed TPU bumper only decelerates it near the end of the stroke. If your application requires fail-safe load holding, you must use an external stop or a separate rod lock.
