Airtac PB Pen-type Cylinder PB16X16U
The AirTAC Airtac PB Pen-type Cylinder PB16X16U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 16mm 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 PB16X16U
The AirTAC PB16X16U is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, driven through an M5x0.8 port. The U suffix denotes a 90-degree perpendicular side air inlet, enabling flat plumbing in confined spaces. Its SUS304 stainless steel barrel and piston rod provide reliable durability in damp or mildly corrosive environments.
This 16 mm bore unit features a 5 mm rod with an M10x1.0 rod-end thread and travels a 16 mm stroke. It relies on a fixed TPU bumper at each end to decelerate the last few millimeters of travel rather than an adjustable air cushion. Because the rod is only 5 mm thick, it is built for coaxial thrust and requires an external guide if subjected to off-axis loads.

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 PB16X16U Is Used
PCB Depaneling Router
Clamps small circuit boards during routing operations, using the 90-degree side inlet to keep pneumatic hoses flush against the machine frame.
Blister Pack Sealing
Closes lightweight aluminum sealing jigs with a 100.5 N push at 0.5 MPa, cycling rapidly without overwhelming the compact tooling fixture.
Parts Divert Gate
Pushes small plastic caps across a conveyor belt, where the fixed TPU bumpers absorb the impact of frequent direction changes at speed.
Is the Airtac PB Pen-type Cylinder PB16X16U the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N, which is roughly 60 percent of the 100.5 N theoretical push at 0.5 MPa, ensuring smooth travel against seal friction. For vertical lifts, this equates to hoisting approximately 5.1 kg with a sane 2:1 safety margin. If your application requires less force, stepping down to the 12 mm bore yields 56.5 N of push at 0.5 MPa, while moving up is not an option as 16 mm is the largest diameter in this series. To confirm your ordering essentials: specify the 16 mm bore, 16 mm stroke, M5x0.8 porting, no sensor magnet, and the U-style 90-degree side inlet. Remember that a plain cylinder like this drifts when air pressure is lost or the valve is centered, so an external rod lock is necessary for fail-safe position 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 PB16X16U FAQ
At 0.5 MPa, this 16 mm bore double-acting cylinder provides 100.5 N of push and 90.7 N of pull. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates between 0.15 and 0.7 MPa at speeds of 50-800 mm/s.
The U suffix indicates a 90-degree perpendicular side air inlet for flat plumbing in tight spaces. Instead of an adjustable air cushion, it uses fixed TPU bumpers at both ends to decelerate the piston near the stroke limits. At high speeds with heavy tooling mass, you should meter-out the exhaust or add an external shock absorber.
