Airtac PB Pen-type Cylinder PB16X45R
The AirTAC Airtac PB Pen-type Cylinder PB16X45R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 45mm 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 PB16X45R
The AirTAC PB16X45R is a JIS pen-size double-acting single-rod mini cylinder featuring a 16mm bore and 45mm stroke. It supplies 100.5 N of push and 90.7 N of pull at 0.5 MPa, relying on a slim SUS304 stainless steel barrel and piston rod to survive damp or mildly corrosive environments. The R suffix indicates an axial air inlet for in-line plumbing, keeping the footprint minimal for tight jigs and light end-of-arm robotic tooling.
Air enters through an M5x0.8 port to drive the Ø5 mm rod, which features an M10x1.0 rod-end thread for secure load coupling. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Because the rod is only 5 mm thick, you should maintain coaxial alignment and add an external linear bearing if the application involves any side load.

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 PB16X45R Is Used
PCB Depaneling Jig
Actuates a cutting blade guide in a tight electronics assembly fixture, using the 100.5 N extend force to sever flex circuits without stressing adjacent components.
Lightweight Pick-and-Place
Drives a small vacuum gripper on a Cartesian robot to lift 5 kg electronics trays vertically, benefiting from the SUS304 build in humid cleanroom environments.
Carton Flap Folder
Tucks small corrugated box flaps at high speed, where the fixed TPU bumper absorbs the end-of-stroke impact provided the exhaust is metered out.
Is the Airtac PB Pen-type Cylinder PB16X45R the Right Cylinder?
This 16mm bore generates 100.5 N push at 0.5 MPa. If you need less force, stepping down to the 12mm bore yields 56.5 N; stepping up is not possible as 16mm is the largest in the PB family. A practical safe working load is about 60 N, which is roughly 60 percent of the 0.5 MPa theoretical output, ensuring smooth travel against seal friction. For vertical lifts, plan to hoist about 5.1 kg to maintain a sane 2:1 safety margin.
When ordering, confirm the 16mm bore, 45mm stroke, M5x0.8 port, and the R axial inlet configuration. Note that a plain PB body does not hold its position if air pressure drops or the valve is centered—the piston will drift. You must add an external stop or rod lock if your process requires fail-safe load 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 PB16X45R FAQ
At 0.5 MPa, this double-acting 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, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The R suffix means the air inlet is axial for in-line plumbing along the cylinder body. It uses a fixed TPU bumper at both ends to decelerate the stroke, which is not adjustable—if you move heavy tooling mass at high speed, meter-out the exhaust or add an external shock absorber. This model has no sensor magnet.
