Airtac PB Pen-type Cylinder PB16X80U
The AirTAC Airtac PB Pen-type Cylinder PB16X80U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 80mm 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 PB16X80U
The AirTAC PB16X80U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, extending up to a maximum 140.7 N push at 0.7 MPa. The slim SUS304 stainless barrel and piston rod provide corrosion resistance for damp environments, while the 80 mm stroke fits neatly into tight jigs and light end-of-arm tooling where space and payload are critical.
This specific configuration features a U-type back cover, meaning the M5x0.8 air ports enter from the side at a 90-degree angle to enable flat, low-profile plumbing along a machine frame. End-of-stroke energy is managed by a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only decelerates the final few millimeters, high-speed cycles with heavy tooling may 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.
Theoretical Output Force (Ø16mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 100.5 N | 90.7 N |
| 0.7 MPa (max) | 140.7 N | 126.9 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 PB16X80U Is Used
PCB Depaneling Router
Actuates a routing tool guide on an electronics assembly line, utilizing the slim stainless body to fit between dense conveyor sections while providing reliable 100.5 N thrust at 0.5 MPa.
Carton Flap Folder
Folds minor flaps on a compact packaging machine, where the 90-degree U-type side inlet keeps pneumatic tubing flush against the frame to avoid snagging on passing cardboard boxes.
Textile Loom Tensioner
Drives a lightweight yarn tensioning lever in a humid textile facility, relying on the SUS304 rod and barrel construction to resist moisture corrosion during continuous high-frequency operation.
Is the Airtac PB Pen-type Cylinder PB16X80U the Right Cylinder?
Selecting this 16 mm bore provides the highest force tier in the PB family. If you need less push, the next size down is the 12 mm bore, which yields a 56.5 N extend force at 0.5 MPa. Since 16 mm is the largest available standard bore in this series, stepping up to greater thrust requires migrating to a different, larger body profile. For this U-type model, confirm your ordering essentials: 16 mm bore, 80 mm stroke, M5x0.8 side-inlet ports, and no magnet.
When sizing your load, plan for a safe working output of about 60 N, which assumes a conservative 60 percent of the 100.5 N theoretical push at 0.5 MPa to account for seal friction. This equates to safely lifting a 5.1 kg mass vertically with a 2:1 safety margin. Note that a plain PB cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, so applications requiring fail-safe holding need an external rod lock or mechanical stop.
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 PB16X80U FAQ
This 16 mm bore double-acting cylinder has a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the push is 140.7 N and the pull is 126.9 N. It operates on filtered air at 0.15-0.7 MPa, runs at speeds between 50-800 mm/s, and has an M10x1.0 rod-end thread.
The U-type back cover provides 90-degree side air inlets, allowing hoses to route parallel to the cylinder body for tight installations. Instead of an adjustable air cushion, it uses fixed TPU bumpers at both ends to absorb impact. If you are moving heavy tooling at high speeds, you should meter-out the exhaust or add an external shock absorber, as the bumpers only decelerate the last few millimeters of travel.
