Airtac PB Pen-type Cylinder PB16X300R
The AirTAC Airtac PB Pen-type Cylinder PB16X300R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 300mm 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 PB16X300R
The AirTAC PB16X300R is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 300mm stroke. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, peaking at 140.7 N push when supplied with the family maximum 0.7 MPa operating pressure. The slim SUS304 stainless steel round barrel and screwed-in covers keep mass low for end-of-arm tooling, while the R suffix denotes a back cover with an axial air inlet for clean in-line plumbing.
This model uses an M5x0.8 port and an M10x1.0 rod-end thread to drive a Ø5 mm piston rod. Because it runs at the maximum standard stroke for this bore, the fixed TPU bumper at each end only decelerates the final few millimeters of travel; for a 300mm extension carrying real tooling mass at 50-800 mm/s, metering out the exhaust or fitting an external shock absorber is advised to prevent bottoming out.

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 PB16X300R Is Used
PCB Shuttle Elevation
Raises populated circuit board trays between test stations, utilizing the 100.5 N push at 0.5 MPa to lift approximately 5.1 kg of tooling weight smoothly.
Package Flap Tucking
Extends 300mm to fold carton flaps on a continuous packaging line, where the compact stainless body resists humid washdown environments.
Textile Yarn Guide
Traverses a thread guide across a winding drum, relying on the axial R inlet for straight plumbing and the fixed TPU bumpers to soften high-frequency direction reversals.
Is the Airtac PB Pen-type Cylinder PB16X300R the Right Cylinder?
Selecting this 16mm bore provides the highest force tier in the PB family; if your task requires less thrust, stepping down to the 12mm bore yields 56.5 N push at 0.5 MPa. Since 16mm is the largest available diameter, there is no larger standard option in this series. Plan for a safe working load of roughly 60 N (about 60% of the 100.5 N figure at 0.5 MPa) to account for seal friction and smooth travel, which equates to lifting about 5.1 kg vertically with a sane 2:1 safety margin.
When ordering, confirm the 300mm stroke, the lack of a sensor magnet, and the R axial inlet configuration. A plain double-acting cylinder like this will drift and cannot hold a vertical load if air pressure is lost or the valve is centered, so an external rod lock or mechanical stop is required for fail-safe positioning. Furthermore, the Ø5 mm rod is built for coaxial thrust; over a 300mm extension, any off-axis load demands an external linear bearing guide to prevent rod bending.
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 PB16X300R FAQ
At 0.5 MPa this 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 at speeds of 50-800 mm/s, with a proof pressure of 1.2 MPa.
No, the PB16X300R does not hold position on air loss and will drift if the valve is centered; an external stop or rod lock is needed for fail-safe holding. It uses fixed non-adjustable TPU bumpers at both ends that only decelerate the last few millimeters, so an external shock absorber is recommended for high-speed or heavy tooling mass.
