Airtac PB Pen-type Cylinder PB16X80SULB
The AirTAC Airtac PB Pen-type Cylinder PB16X80SULB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 80mm 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 PB16X80SULB
The AirTAC PB16X80SULB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel round barrel and piston rod to endure damp or mildly corrosive production lines. This 16 mm bore unit breathes through an M5x0.8 port and drives an M10x1.0 rod-end thread.
Fitted with a built-in piston magnet (S), it accepts AirTAC reed or electronic switches for position detection. The U designation provides a 90-degree side air inlet for flat plumbing, while the LB bracket supplies a robust mounting interface. Because the fixed TPU bumper only decelerates the final few millimeters of travel, high-speed tooling masses 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 PB16X80SULB Is Used
PCB Depaneling Router
Pushes a light carrier fixture against a fixed stop on an electronics depaneling machine, utilizing the 100.5 N thrust at 0.5 MPa without stressing the fragile board.
Carton Flap Folder
Folds small corrugated carton flaps on a packaging line, where the 90-degree U side inlet keeps pneumatic plumbing flush against the machine frame to save space.
Lab Tube Lift
Raises a thin rack of sample tubes vertically, safely lifting about 5.1 kg when operated at 0.5 MPa while the LB bracket secures the body to the analyzer chassis.
Is the Airtac PB Pen-type Cylinder PB16X80SULB the Right Cylinder?
Selecting this 16 mm bore yields 100.5 N push at 0.5 MPa. If you need less force, stepping down to the 12 mm bore drops the output to 56.5 N. If your jig requires more thrust, there is no larger standard PB bore, so you would transition to a different profiled body family. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa figure) to account for seal friction, which equates to lifting about 5.1 kg vertically with a sane 2:1 margin.
The thin Ø5 mm piston rod is designed strictly for coaxial thrust; over the 80 mm stroke, any off-axis load mandates an external linear bearing guide. Furthermore, a plain PB-type body does not hold its load if air pressure drops or the valve is centered—the piston will drift, as the bumper only decelerates near stroke end and acts as neither a lock nor a brake. To secure a suspended load safely, specify an external rod lock. Confirm your ordering essentials: 16 mm bore, 80 mm stroke, M5x0.8 port, S magnet, U side inlet, and LB mount.
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 PB16X80SULB 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 proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, a plain PB-type cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper at each end only decelerates the piston near the stroke limits; it does not function as a lock or brake. An external rod lock or mechanical stop is required for fail-safe load holding.
