Airtac PB Pen-type Cylinder PB16X85R
The AirTAC Airtac PB Pen-type Cylinder PB16X85R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 85mm 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 PB16X85R
The AirTAC PB16X85R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 16mm bore and an 85mm stroke, generating 100.5 N of push force and 90.7 N of pull force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling.
This configuration includes an R axial air inlet for in-line plumbing and uses an M5x0.8 port. Travel speed reaches 50-800 mm/s, with a fixed TPU bumper at each end to absorb end-of-stroke impact. The piston rod end features an M10x1.0 thread for secure load coupling. Plan for a safe working load of roughly 60 N, which accounts for seal friction at standard 0.5 MPa operation.

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 PB16X85R Is Used
PCB Depaneling Router
Provides the precise 100.5 N thrust at 0.5 MPa needed to drive a cutting blade through rigid circuit boards without stressing delicate surface-mount components.
Carton Flap Folder
Extends rapidly at 50-800 mm/s to tuck corrugated cardboard flaps on a continuous packaging line, utilizing the fixed TPU bumper to soften the stroke end.
Sorting Diverter Arm
Pushes lightweight parcels laterally off a main conveyor belt, benefiting from the SUS304 stainless construction that resists humidity in wash-down logistics hubs.
Is the Airtac PB Pen-type Cylinder PB16X85R the Right Cylinder?
When sizing this actuator, stepping down to the 12mm bore yields 56.5 N of push force at 0.5 MPa, making the 16mm version the correct choice when you need approximately 100.5 N of theoretical thrust. Since 16mm is the largest bore in this series, there is no larger standard option to step up to within the PB family. If your mechanism must hold a vertical load without live pressure, note that this cylinder will drift when air is lost or the valve is centered; an external rod lock or mechanical stop is required for fail-safe positioning.
Confirm your ordering essentials to ensure a seamless fit: 16mm bore, 85mm stroke, M5x0.8 port, no sensor magnet, R axial inlet, and standard mounting. The thin 5mm rod is designed strictly for coaxial thrust, so over this 85mm stroke you should incorporate an external linear bearing if the payload presents any side load.
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 PB16X85R 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 and a speed range of 50-800 mm/s.
No, a plain pen-size cylinder does not hold its position or load when air is lost or the valve is centered. The piston will drift, and the fixed TPU bumper only decelerates the rod near the stroke end rather than locking it. You must add an external stop or rod lock for fail-safe load holding.
