Airtac PB Pen-type Cylinder PB10X20R
The AirTAC Airtac PB Pen-type Cylinder PB10X20R is a double-acting pen-size (mini) air cylinder with a Ø10mm bore and 20mm 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 PB10X20R
The AirTAC PB10X20R is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. It generates 39.3 N of push and 33 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a 4 mm piston rod that naturally resist damp or mildly corrosive industrial environments. The R designation specifies an axial air inlet, providing clean in-line plumbing for tight spaces.
This 10 mm bore unit features an M5x0.8 port and an M8x1.0 rod-end thread for straightforward load coupling. It relies on a fixed TPU bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Because the rod is only 4 mm thick, it is built for coaxial thrust and requires an external guide if subjected to off-axis loads over its 20 mm travel.

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 PB10X20R Is Used
PCB Depaneling Jig
Actuates a small cutting blade or clamping finger in a light electronic assembly fixture, utilizing the slim stainless body to fit within dense router arrays.
Label Tamp Mechanism
Extends 20 mm to press an adhesive label onto small pharmaceutical cartons, where the fixed TPU bumper absorbs the repetitive end-of-stroke impact.
Lab Sample Ejector
Pushes processed vials out of a centrifuge carousel using the 39.3 N extend force, benefiting from the axial R inlet for flush manifold mounting.
Is the Airtac PB Pen-type Cylinder PB10X20R 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. For vertical lifts, this equates to raising approximately 2 kg safely with a 2:1 margin. If your application demands 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, 20 mm stroke, M5x0.8 porting, no sensor magnet, and the R axial back cover. Note 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 end of travel. An external rod lock or stop is required for fail-safe load 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 PB10X20R 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 speed range of 50-800 mm/s.
No, this specific model does not include a sensor magnet. To use AirTAC reed or electronic switches, you must select the PB10X20RS variant. Additionally, the fixed TPU bumper is not adjustable, so for high-speed cycling with heavy tooling, meter-out the exhaust or add an external shock absorber.
