Airtac PB Pen-type Cylinder PB16X110U
The AirTAC Airtac PB Pen-type Cylinder PB16X110U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 110mm 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 PB16X110U
The AirTAC PB16X110U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 100.5 N of push force at 0.5 MPa, it provides robust thrust within a tiny footprint.
This 16 mm bore model uses an M5x0.8 air port and a 90-degree U side inlet for flat plumbing against machine frames. It operates at 50-800 mm/s with a fixed TPU bumper at each end to decelerate the stroke. Because the bumper is non-adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving heavy tooling mass at higher speeds.

| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |

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 PB16X110U Is Used
PCB Depaneling Router
Drives a light cutting head along an 110 mm path to singulate printed circuit boards, utilizing the slim stainless barrel to fit between tight routing fixtures.
Carton Flap Folder
Folds small corrugated box flaps at high speed, where the 90-degree U inlet keeps air plumbing flush against the conveyor frame to save space.
Lab Sample Dispenser
Actuates a pipette or valve assembly for liquid handling in wet laboratory environments, benefiting from the SUS304 construction against mild chemical splash.
Is the Airtac PB Pen-type Cylinder PB16X110U the Right Cylinder?
When sizing this actuator, stepping down to the 12 mm bore yields 56.5 N push at 0.5 MPa, while this 16 mm unit provides 100.5 N. As the largest in the family, it is the top choice for maximum thrust within the pen-size format. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel. For vertical lifts, expect to raise about 5.1 kg safely with a 2:1 margin.
Confirm your ordering essentials: 16 mm bore, 110 mm stroke, M5x0.8 port, U side inlet, and no sensor magnet. The Ø5 mm piston rod is built for coaxial thrust; over the 110 mm stroke, add an external linear bearing if the load imposes any side load. Note that a plain PB body does not hold position on air loss—the piston drifts, so an external rod lock is required for fail-safe 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 PB16X110U 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 cylinder operates at 0.15-0.7 MPa with a speed range of 50-800 mm/s.
The U back cover provides a 90-degree side air inlet for flat plumbing in tight spaces. Instead of an adjustable air cushion, it uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters. For high-speed or heavy loads, add an external shock absorber to prevent bottoming out.
