Airtac PB Pen-type Cylinder PB10X50U
The AirTAC Airtac PB Pen-type Cylinder PB10X50U is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 50mm 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 PB10X50U
The AirTAC PB10X50U is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency motion. It provides 39.3 N of push and 33 N of pull at 0.5 MPa, driven through an M5x0.8 port. The U suffix designates a 90-degree side air inlet, allowing flat plumbing in confined spaces. Its slim SUS304 stainless round barrel and screwed-in covers keep weight low for end-of-arm tooling.
This 10 mm bore unit features a 4 mm rod with an M8x1.0 rod-end thread. It relies on a fixed TPU bumper at each end to decelerate the last few millimeters of travel rather than an adjustable air cushion. Because the rod is only 4 mm thick, it is built for coaxial thrust; over the 50 mm stroke, adding an external guide prevents side-load wear.

| 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 |

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 PB10X50U Is Used
PCB Pick-and-Place
Drives a small vacuum cup on a pick-and-place head to lift delicate printed circuit boards, utilizing the 2 kg safe vertical lift capacity without crushing components.
Carton Flap Folding
Extends a narrow jig to tuck minor flaps on small packaging boxes, where the 90-degree side inlet keeps airlines flush against the machine frame.
Lab Dispenser Actuation
Pushes a syringe plunger for automated chemical dispensing, benefiting from the SUS304 stainless build in damp environments and the compact pen-size footprint.
Is the Airtac PB Pen-type Cylinder PB10X50U the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 24 N, which is about 60 percent of the 39.3 N theoretical push at 0.5 MPa. In vertical lift scenarios, this translates to lifting approximately 2 kg with a sane 2:1 safety margin. If you need less force, stepping down to the 6 mm bore yields 14.2 N of push, while stepping up to the 12 mm bore provides 56.5 N at the same pressure.
Remember that a plain double-acting cylinder drifts when air is lost or the valve is centered, as the bumper only decelerates near stroke end and cannot hold a load. To configure this model correctly, confirm the 10 mm bore, 50 mm stroke, M5x0.8 port, no sensor magnet, and the U 90-degree side inlet.
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 PB10X50U FAQ
At 0.5 MPa this 10 mm bore cylinder outputs 39.3 N push and 33 N pull. At the maximum operating pressure of 0.7 MPa, it yields 55 N push and 46.2 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not an adjustable air cushion. For high mass or speed, meter-out the exhaust or add an external shock absorber. It does not hold position on air loss, so an external rod lock is needed for fail-safe holding.
