Airtac PB Pen-type Cylinder PB16X240U
The AirTAC Airtac PB Pen-type Cylinder PB16X240U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 240mm 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 PB16X240U
The AirTAC PB16X240U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency 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 resist damp or mildly corrosive industrial environments. The U suffix equips the rear cover with a 90-degree perpendicular air inlet, allowing flat plumbing in confined spaces.
This 16 mm bore unit features a 240 mm stroke and uses an M5x0.8 port paired with an M10x1.0 rod-end thread. Travel speed reaches 50-800 mm/s, with fixed TPU bumpers at both ends to absorb end-of-stroke impact. Because the rod is a slender Ø5 mm, maintaining coaxial thrust is critical over this long extension; adding an external linear guide prevents side-load binding.

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 PB16X240U Is Used
Package Flap Folding
Pushes corrugated cardboard flaps down on a continuous packaging line, utilizing the 240 mm stroke to clear varying box heights before the sealing head.
PCB Test Fixture
Drives a bed-of-nails test probe assembly downward into printed circuit boards, where the SUS304 body withstands mild flux fumes and cleaning solvents.
Light-Part Elevation
Lifts small stamped metal brackets between a lower conveyor and an upper machining cell, safely handling parts well under the 5.1 kg vertical lift threshold.
Is the Airtac PB Pen-type Cylinder PB16X240U the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N, which represents about 60% of the 100.5 N theoretical push at 0.5 MPa to account for seal friction. For vertical lifts, this translates to safely raising around 5.1 kg with a 2:1 safety margin. If your application requires slightly less force, stepping down to the 12 mm bore yields 56.5 N push at 0.5 MPa. Since 16 mm is the largest diameter in this series, moving beyond 140.7 N maximum push at 0.7 MPa requires transitioning to a larger profile body.
Confirm your ordering essentials: 16 mm bore, 240 mm stroke, M5x0.8 port, no sensor magnet, and the U-type 90-degree side inlet. Note that a plain PB body does not hold position if air pressure drops or the valve is centered; the piston will drift, so an external rod lock is required for fail-safe holding. The fixed bumpers only decelerate the last few millimeters of travel, so for heavy tooling mass at high speed, meter-out the exhaust or add an external shock absorber.
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 PB16X240U 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, push is 140.7 N and pull is 126.9 N. The cylinder operates between 0.15-0.7 MPa, handles speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The U designates a 90-degree perpendicular side air inlet on the back cover, which allows flat plumbing in tight spaces. Additionally, this model uses fixed TPU bumpers at both ends rather than adjustable air cushions, meaning high-speed loads may require external shock absorption.
