Airtac PB Pen-type Cylinder PB16X180U
The AirTAC Airtac PB Pen-type Cylinder PB16X180U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 180mm 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 PB16X180U
The AirTAC PB16X180U is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 180mm stroke. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing an M5x0.8 air port and an M10x1.0 rod-end thread. The U suffix specifies a 90-degree side air inlet, allowing flat plumbing in confined spaces. Its SUS304 stainless steel barrel and piston rod provide reliable durability in damp or mildly corrosive environments.
Because this model lacks the -S magnet, it cannot host AirTAC position switches. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. This bumper only absorbs impact over the final few millimeters, so when moving real tooling mass at high speed you should meter-out the exhaust or install 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 PB16X180U Is Used
PCB Depaneling Router
Pushes a carrier fixture forward to the cutting head on an electronics assembly line, where the slim 16mm body saves valuable tooling space.
Carton Flap Folder
Tucks minor flaps on a packaging conveyor prior to tape sealing, using the 90-degree U inlet to keep air hoses flush against the machine frame.
Lab Sample Dispenser
Actuates a dosing probe in a wet analytical instrument, relying on the SUS304 stainless construction to withstand mild chemical exposure.
Is the Airtac PB Pen-type Cylinder PB16X180U the Right Cylinder?
This 16mm bore generates 100.5 N of thrust at 0.5 MPa. A practical safe working load is about 60 N (roughly 60 percent of the theoretical force) to account for seal friction. If you need to lift a mass vertically, plan for around 5.1 kg to maintain a sane 2:1 safety margin. If your application requires less force, stepping down to the 12mm bore yields 56.5 N push at 0.5 MPa; since 16mm is the largest in this family, stepping up requires a different cylinder series entirely.
When ordering, confirm the 16mm bore, 180mm stroke, M5x0.8 port, and the U 90-degree side inlet. Note that a plain pneumatic actuator does not hold its position if air pressure drops or the valve is centered—the piston will drift. For fail-safe load holding, an external rod lock or mechanical stop is required. Additionally, the Ø5 mm rod is built for coaxial thrust; over this 180mm stroke, avoid side loading by adding an external linear guide.
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 PB16X180U FAQ
At 0.5 MPa the push force is 100.5 N and the pull force is 90.7 N. At the maximum operating pressure of 0.7 MPa, the push is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s and a proof pressure of 1.2 MPa.
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. If you move heavy tooling at high speed, add an external shock absorber. Furthermore, it does not hold its load if air is lost—the piston drifts, so an external stop is needed for fail-safe holding.
