The AirTAC Airtac PB Pen-type Cylinder PB10X20U 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.
The AirTAC PB10X20U is a double-acting JIS pen-size 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 10 mm bore and a 20 mm stroke. The U option designates a 90-degree side air inlet, allowing flat plumbing in confined spaces. Its slim round SUS304 stainless barrel and piston rod provide reliable durability in damp or mildly corrosive environments.
Air enters via an M5x0.8 port to drive the 4 mm rod, which features an M8x1.0 rod-end thread for secure load coupling. Operating speeds reach 50-800 mm/s, with a fixed TPU bumper at each end to absorb impact. Because the bumper only decelerates the final few millimeters of travel, high-speed cycles with real tooling mass require metering out the exhaust or adding an external shock absorber.

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.
| 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.

Actuates a small cutting blade or clamping finger in a tight electronics assembly fixture where the 90-degree side inlet keeps plumbing flush against the machine frame.
Provides a short 20 mm stroke to press adhesive labels onto lightweight cartons, utilizing the 39.3 N push force without crushing the packaging material.
Ejects small vials from a testing carousel in a humid laboratory environment, relying on the SUS304 stainless build to resist moisture and chemical exposure.
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. This equates to lifting approximately 2 kg vertically with a sane 2:1 safety margin. If your application requires 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.
Note that a plain PB body does not hold its position if air pressure drops or the valve is centered; the piston will drift, so an external stop or rod lock is required for fail-safe holding. The thin 4 mm rod is built for coaxial thrust, so avoid side loading or add a linear bearing for off-axis guidance. To order, confirm the 10 mm bore, 20 mm stroke, M5x0.8 porting, the U 90-degree side inlet, and your desired mounting bracket.
Quick checklist
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 is 55 N and the pull is 46.2 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper at each end only decelerates the rod near the stroke ends and does not act as a lock or brake. For vertical load holding, you must install an external stop or rod lock.
