Airtac PB Pen-type Cylinder PB16X150U
The AirTAC Airtac PB Pen-type Cylinder PB16X150U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 150mm 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 PB16X150U
The AirTAC PB16X150U is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 150mm stroke. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, making it the highest force class in this compact family. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight.
This specific configuration includes a U-type back cover, providing a 90-degree perpendicular air inlet for flat plumbing in confined spaces. Air connects via an M5x0.8 port, and the load fastens to an M10x1.0 rod-end thread on a 5mm piston rod. Travel speed reaches 50-800 mm/s, with fixed TPU bumpers at both ends to absorb impact during direction changes.

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 PB16X150U Is Used
Package Diverting
Pushes small cartons off a sorting line using 100.5 N of extend force, fitting neatly into narrow conveyor frames.
PCB Test Fixture
Drives a probe block down onto printed circuit boards, relying on the fixed TPU bumper to soften the final contact.
Lightweight Vertical Lift
Raises 5 kg electronic housings between processing stations, requiring an external guide to keep the 5mm rod coaxial.
Is the Airtac PB Pen-type Cylinder PB16X150U the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N, which accounts for seal friction at 0.5 MPa. For vertical lifts, this equates to raising about 5.1 kg with a sane 2:1 safety margin. If you need slightly less force, the adjacent 12mm bore provides 56.5 N push at 0.5 MPa; since 16mm is the largest in this series, stepping up to a larger profile body is required for heavier loads. The thin 5mm rod handles coaxial thrust well, but over this 150mm stroke you should add an external linear bearing if any off-axis load is present.
A plain double-acting cylinder like this will drift and cannot hold a vertical load if air pressure drops or the valve is centered—the end bumpers only decelerate travel near the stroke limits, acting neither as a lock nor a brake. To finalize your order, confirm the 16mm bore, 150mm stroke, M5x0.8 porting, U-type 90-degree inlet, and the absence of a sensor magnet.
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 PB16X150U 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, push is 140.7 N and pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa, and speeds of 50-800 mm/s.
The U designation means the back cover has a 90-degree perpendicular air inlet for flat plumbing. For deceleration, it uses fixed TPU bumpers at both ends rather than adjustable air cushions. At high speeds with heavy tooling mass, these bumpers can bottom out, so you should meter-out the exhaust or add an external shock absorber.
