Airtac PB Pen-type Cylinder PB16X20R
The AirTAC Airtac PB Pen-type Cylinder PB16X20R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 20mm 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 PB16X20R
The AirTAC PB16X20R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, utilizing a 16 mm bore and a short 20 mm stroke. The slim SUS304 stainless round barrel and piston rod provide durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight.
This configuration features an R axial air inlet for in-line plumbing and an M5x0.8 port. It operates at speeds from 50-800 mm/s and relies on a fixed TPU bumper at each end to decelerate the piston near stroke end. Because the rod is only Ø5 mm, it is built for coaxial thrust rather than side loading, requiring an external guide if handling off-axis forces over longer extensions.

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 PB16X20R Is Used
PCB Depaneling Jig
Drives a small cutting blade or separator pin in a tight electronics assembly fixture, using the 100.5 N push force to snap circuit boards apart cleanly.
Carton Flap Folder
Folds small corrugated box flaps on a packaging line where the short 20 mm stroke and compact pen-size body fit neatly between conveyor belts.
Lightweight Vertical Lift
Raises delicate electronic components weighing up to 5.1 kg, applying a 2:1 safety margin on the 0.5 MPa vertical lift capacity for smooth robotic integration.
Is the Airtac PB Pen-type Cylinder PB16X20R the Right Cylinder?
Selecting this 16 mm bore model gives you the highest standard force tier in the PB family, pushing 100.5 N at 0.5 MPa. If you need slightly less force, the next size down is the Ø12 bore, which provides a 56.5 N push at 0.5 MPa. As the largest available diameter in this series, there is no larger standard bore to step up to. Plan for a safe working load of roughly 60 N, which is about 60% of the 0.5 MPa theoretical push, to account for seal friction and smooth travel.
When ordering, confirm the 16 mm bore, 20 mm stroke, M5x0.8 port, and the R axial inlet configuration. This unit does not include a sensor magnet. Note that a plain PB cylinder will not hold a load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the end of the stroke, 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 PB16X20R 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 is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters. This bumper is not adjustable or a locking brake, so at high speeds with real tooling mass you should meter-out the exhaust or add an external shock absorber. If air is lost, the cylinder will not hold its load and will drift, requiring an external stop for fail-safe positioning.
