Airtac PB Pen-type Cylinder PB16X35R
The AirTAC Airtac PB Pen-type Cylinder PB16X35R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 35mm 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 PB16X35R
The AirTAC PB16X35R is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 35mm stroke. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, driven through an M5x0.8 port. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping the payload low for end-of-arm tooling.
This variant uses an R axial air inlet for straightforward in-line plumbing. Because it lacks a sensor magnet, position detection is not supported out of the box. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion, meaning the last few millimeters of travel are absorbed by the elastomer. For high-speed cycling with heavy tooling, adding an external shock absorber is advisable.

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 PB16X35R Is Used
PCB Depaneling Router
Provides the 100.5 N extend force needed to clamp populated circuit boards securely during routing, with the slim stainless body fitting neatly into dense electronics assembly machinery.
Carton Flap Folder
Actuates at 50-800 mm/s to tuck minor flaps on small packaging lines, where the fixed TPU bumper absorbs the end-of-stroke impact without requiring external adjustment.
Lightweight Vertical Lift
Raises small electronic components weighing up to 5.1 kg, offering a 2:1 safety margin over the 0.5 MPa vertical lift capacity for smooth, gravity-loaded operations.
Is the Airtac PB Pen-type Cylinder PB16X35R the Right Cylinder?
When sizing this actuator, stepping down to a 12mm bore yields 56.5 N of push at 0.5 MPa, while there is no larger standard option in the PB family. The 16mm bore thus provides the maximum thrust available in this series. Plan for a safe working load of roughly 60 N, which accounts for seal friction at 0.5 MPa, rather than utilizing the full theoretical output.
A standard PB body drifts when air pressure is removed or the valve is centered, as the internal bumper only decelerates the piston near the stroke end and does not function as a locking mechanism. If your process requires fail-safe load holding, an external rod lock or mechanical stop must be installed. To order, confirm the 16mm bore, 35mm stroke, M5x0.8 porting, R axial inlet, and the absence of a magnet.
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 PB16X35R 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 and a proof pressure of 1.2 MPa.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters, which is not field-adjustable. It does not hold position if air is lost; the piston will drift, so an external stop is required for fail-safe load holding. The Ø5 mm rod is designed for coaxial thrust, so avoid side loading.
