Airtac PB Pen-type Cylinder PB16X100ULB
The AirTAC Airtac PB Pen-type Cylinder PB16X100ULB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 100mm 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 PB16X100ULB
The AirTAC PB16X100ULB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It generates 100.5 N of push force and 90.7 N of pull force at 0.5 MPa, utilizing a 16 mm bore and 100 mm stroke. The slim SUS304 stainless steel round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while saving critical space on light end-of-arm tooling.
This specific configuration includes a U-style 90-degree side air inlet for flat plumbing and an LB mounting bracket for secure attachment. Air connections use an M5x0.8 port, and the Ø5 mm piston rod features an M10x1.0 rod-end thread. Deceleration is handled by a fixed TPU bumper at each end, which is not field-adjustable, meaning high-speed cycles with heavy tooling may 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 PB16X100ULB Is Used
PCB Depaneling Router
Provides the 100.5 N extension thrust to plunge a small routing spindle into assembled circuit boards, with the SUS304 body resisting flux-laden ambient moisture.
Carton Flap Folder
Actuates a lightweight mechanical arm to tuck minor flaps on small product boxes, using the U side inlet to keep pneumatic plumbing flush against the machine frame.
Bottle Sorting Diverter
Pushes plastic bottles into a secondary packaging lane at high speed, relying on the fixed TPU bumper to absorb the impact energy of the 100 mm stroke.
Is the Airtac PB Pen-type Cylinder PB16X100ULB the Right Cylinder?
When sizing this actuator, 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. In vertical lift applications, this equates to lifting about 5.1 kg with a sane 2:1 safety margin. If you need slightly less force, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa; stepping up is not available as Ø16 is the largest in this family. Be aware that a plain PB cylinder does not hold its load if air pressure is lost or the valve is centered, as the piston will drift and the bumper only decelerates near the stroke end, so an external rod lock is required for fail-safe holding.
Confirm your ordering essentials: 16 mm bore, 100 mm stroke, M5x0.8 port, no sensor magnet, U 90-degree side inlet, and LB mounting bracket. The thin Ø5 mm rod is designed strictly for coaxial thrust, so over the 100 mm stroke or under off-axis loads, add an external linear bearing guide to prevent side-load damage.
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 PB16X100ULB 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 proof pressure of 1.2 MPa. Operating speed ranges from 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not an adjustable air cushion. If cycling at high speeds with real tooling mass, you should meter-out the exhaust or add an external shock absorber. Additionally, it does not hold position on air loss, so an external stop is needed for fail-safe load holding.
