About the Airtac PB Pen-type Cylinder PB16X140U
The AirTAC PB16X140U is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and a 140mm 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 U suffix designates a 90-degree side air inlet, allowing flat plumbing in confined spaces. Its slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments.
This model is equipped with a fixed TPU bumper at each end to decelerate the piston over the final few millimeters of travel. Because the bumper is not adjustable, high-speed cycles with heavy tooling mass may require metering out the exhaust or adding an external shock absorber. The M5x0.8 port and M10x1.0 rod-end thread ensure secure, standard pneumatic connections for your jigs.

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 PB16X140U Is Used
Package Flap Folding
Pushes corrugated carton flaps during automated packing lines, utilizing the 100.5 N extend force to overcome cardboard resistance reliably.
Small Parts Ejection
Ejects machined aluminum components from a CNC fixture, where the compact round body saves valuable space on the machine tooling plate.
Lab Sample Diverting
Actuates a diverter gate for fluid sample tubes, benefiting from the SUS304 stainless construction in humid laboratory environments.
Is the Airtac PB Pen-type Cylinder PB16X140U the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø12 bore if you need less force (56.5 N push at 0.5 MPa) for lighter duties, as the Ø16 is the largest available in this series. Plan for a safe working load of about 60 N, which is roughly 60% of the 100.5 N theoretical push at 0.5 MPa, ensuring smooth travel after accounting for seal friction. For vertical lifts, this equates to raising about 5.1 kg safely with a 2:1 margin. Keep in mind a plain PB cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift, so an external rod lock is required for fail-safe holding.
To order, confirm the essentials: 16mm bore, 140mm stroke, M5x0.8 port, no sensor magnet, and the U 90-degree side inlet. The Ø5 mm piston rod is designed for coaxial thrust, so over this 140mm stroke, avoid side loading by adding an external guide or linear bearing.
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 PB16X140U 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.
The U suffix indicates a 90-degree perpendicular side air inlet for flat plumbing in tight spaces. It uses a fixed TPU bumper at each end to decelerate travel, which is not adjustable or a locking brake. For high-speed loads, you should meter-out the exhaust or add an external shock absorber.
