Airtac PB Pen-type Cylinder PB16X210R
The AirTAC Airtac PB Pen-type Cylinder PB16X210R is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 210mm 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 PB16X210R
The AirTAC PB16X210R 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, extending 210 mm via a Ø5 mm stainless piston rod. The slim SUS304 round barrel saves valuable space and reduces payload on light end-of-arm tooling where bulkier actuators cannot fit. This specific configuration uses an R axial air inlet for clean in-line plumbing.
Because this model lacks a sensor magnet, position detection requires an external method. Impact at stroke ends is managed by a fixed TPU bumper rather than an adjustable air cushion. This bumper only decelerates the piston over the final few millimeters, so driving heavy tooling at high speeds demands metering out the exhaust or adding an external shock absorber. The M5x0.8 port and M10x1.0 rod-end thread ensure straightforward integration into your existing pneumatic circuits and mechanical linkages.

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 PB16X210R Is Used
Package Flap Folding
Pushes cardboard flaps down on a carton sealing line, utilizing the 210 mm stroke to clear varying box widths before the tape head applies the seal.
PCB Reject Arm
Extends a lightweight paddle to divert defective printed circuit boards off a testing conveyor, relying on the 100.5 N push force at 0.5 MPa to move the small panels swiftly.
Tote Diverting Gate
Actuates a pivoting diverter gate on a gravity roller conveyor to route small plastic totes, taking advantage of the compact pen-size body to fit within the tight side-frame clearance.
Is the Airtac PB Pen-type Cylinder PB16X210R the Right Cylinder?
Choosing this 16 mm bore actuator provides the highest standard force in the PB family. If your application requires less energy, the next size down is the 12 mm bore, which yields a 56.5 N push at 0.5 MPa. Since 16 mm is the largest available option in this series, stepping up to a larger profile body is necessary for heavier loads. For this specific 210 mm stroke, the slender Ø5 mm rod is highly susceptible to side-loading and buckling; always utilize an external linear bearing guide to maintain strict coaxial thrust. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel.
When ordering, confirm the essentials: 16 mm bore, 210 mm stroke, M5x0.8 port, no magnet, and the R axial back cover inlet. Note that a plain PB-type cylinder does not hold its position or load when air pressure is lost or the valve is centered—the piston will drift. If your machinery requires fail-safe load holding, you must incorporate an external stop or a dedicated rod lock. At 0.5 MPa, this actuator can safely lift a vertically oriented mass of about 5.1 kg with a standard 2:1 safety margin.
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 PB16X210R FAQ
The PB16X210R generates a push force of 100.5 N and a pull force of 90.7 N at 0.5 MPa. 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. It operates at speeds between 50-800 mm/s across a temperature range of -20 to +70 C.
It uses a fixed TPU bumper at each end to decelerate the piston over the final few millimeters; this is not an adjustable air cushion. If you are moving real tooling mass at high speeds, you should meter-out the exhaust or install an external shock absorber. Additionally, it does not hold its load if air is lost or the valve is centered, so an external stop or rod lock is required for fail-safe positioning.
