Airtac PB Pen-type Cylinder PB16X105SU
The AirTAC Airtac PB Pen-type Cylinder PB16X105SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 105mm 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 PB16X105SU
The AirTAC PB16X105SU is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 105mm 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 SUS304 stainless steel barrel and piston rod provide excellent durability in damp or mildly corrosive environments, while the slim round profile saves valuable space on tight jigs and light end-of-arm tooling.
This specific configuration includes a built-in piston magnet (S) for position detection and a U-type back cover offering a 90-degree perpendicular air inlet for flat plumbing. Operating pressure ranges from 0.15 to 0.7 MPa, and the M5x0.8 port ensures reliable airflow. The Ø5 mm rod ends in an M10x1.0 thread for secure load coupling, and end-of-stroke deceleration is handled by fixed TPU bumpers rather than adjustable cushions.

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 PB16X105SU Is Used
PCB Depaneling Router
Drives a light cutting head on an electronic assembly line, utilizing the 90-degree side inlet to keep plumbing flat against the machine frame while routing printed circuit boards.
Blister Pack Sealing
Cycles a small heated platen to press and seal pharmaceutical blister packs, relying on the 100.5 N extend force and fixed TPU bumpers to absorb high-frequency impact.
Sorter Diverter Arm
Actuates a lightweight diverter gate on a package routing conveyor, where the built-in S magnet triggers a reed or electronic switch to confirm package redirection.
Is the Airtac PB Pen-type Cylinder PB16X105SU the Right Cylinder?
When sizing this model, consider stepping down to the Ø12 bore (56.5 N push at 0.5 MPa) for lighter tasks, or recognize that Ø16 is the largest available in this series, offering the maximum 100.5 N push at 0.5 MPa. For practical applications, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel. This equates to lifting about 5.1 kg vertically with a sane 2:1 safety margin.
Keep in mind that a plain PB cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, so an external stop or rod lock is required for fail-safe holding. To order, confirm your essentials: 16mm bore, 105mm stroke, M5x0.8 port, S magnet, U 90-degree side inlet, and your desired mounting bracket.
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 PB16X105SU FAQ
At 0.5 MPa, this 16mm bore cylinder provides 100.5 N push and 90.7 N pull. At the maximum operating pressure of 0.7 MPa, it yields 140.7 N push and 126.9 N pull. It operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
It uses fixed TPU bumpers at both ends to decelerate the piston over the last few millimeters; these are not adjustable, so for high-speed or heavy tooling mass you should meter-out the exhaust or add an external shock absorber. Additionally, it does not hold its load on air loss or valve centering—the piston drifts, requiring an external rod lock for fail-safe holding.
