Airtac PB Pen-type Cylinder PB16X65U
The AirTAC Airtac PB Pen-type Cylinder PB16X65U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 65mm 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 PB16X65U
The AirTAC PB16X65U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 16mm bore and a 65mm stroke, generating 100.5 N of push and 90.7 N of pull at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide corrosion resistance for damp production zones, while keeping mass low for end-of-arm robotic tooling.
This specific configuration includes a U-type back cover, providing a 90-degree perpendicular air inlet for flat plumbing in confined spaces. The body uses an M5x0.8 port and a fixed TPU bumper at each end to decelerate the stroke. Because the bumper only absorbs impact over the final few millimeters, high-speed cycles with heavy tooling 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 PB16X65U Is Used
PCB Depaneling Router
Actuates a cutting head guide on an electronics depaneling machine, utilizing the 90-degree U inlet to keep pneumatic tubing flush against the machine frame.
Carton Flap Folder
Folds minor flaps on a compact packaging line, where the SUS304 stainless rod withstands occasional washdowns and the 100.5 N push at 0.5 MPa easily overcomes light cardboard resistance.
Vertical Part Ejector
Lifts small molded plastic parts out of a die, lifting about 5.1 kg vertically with a 2:1 safety margin at 0.5 MPa before releasing them onto a downstream conveyor.
Is the Airtac PB Pen-type Cylinder PB16X65U the Right Cylinder?
Selecting this 16mm bore provides the highest standard force in the PB family, delivering a maximum push of 140.7 N at 0.7 MPa. If your application requires less force, stepping down to the 12mm bore yields 56.5 N of push at 0.5 MPa. Since 16mm is the largest available bore in this series, there is no larger standard option; for higher loads, consider a different cylinder family entirely. Plan for a safe working load of roughly 60 N (about 60% of the 100.5 N figure at 0.5 MPa) to account for seal friction and smooth travel.
When ordering, confirm the 16mm bore, 65mm stroke, M5x0.8 port, and the U-type 90-degree side inlet. This model does not include a sensor magnet. Note that a plain PB cylinder will not hold a load if air pressure is lost or the valve is centered; the piston will drift, and the bumper only decelerates near the stroke end. A fail-safe hold requires an external stop or rod lock.
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 PB16X65U 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 force is 140.7 N and the pull force is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
The U back cover provides a 90-degree perpendicular air inlet for flat plumbing in tight spaces. The cylinder uses a fixed TPU bumper at each end to decelerate the piston over the final few millimeters; it is not an adjustable air cushion, so high-speed cycles with real tooling mass may require an external shock absorber.
