Airtac PB Pen-type Cylinder PB16X200U
The AirTAC Airtac PB Pen-type Cylinder PB16X200U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 200mm 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 PB16X200U
The AirTAC PB16X200U is a double-acting JIS pen-size mini cylinder engineered for compact automation. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a Ø5 mm rod. The integrated U back cover provides a 90-degree perpendicular air inlet, allowing flat plumbing in confined spaces. Air connections use an M5x0.8 port.
Because the rod extends 200 mm, maintaining coaxial alignment is critical to prevent side loading on the slender Ø5 mm shaft; adding an external linear bearing is advised for heavy tooling. The cylinder relies on a fixed TPU bumper at each end to decelerate the piston over the final few millimeters. For high-speed cycles carrying real mass, metering out the exhaust or installing an external shock absorber prevents the bumpers from bottoming out.

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 PB16X200U Is Used
Package Diverter Arm
Pushes lightweight cardboard cartons on a packing line using the 90-degree U inlet to keep pneumatic tubing flush against the machine frame.
PCB Test Fixture
Drives a probe block over 200 mm to contact circuit boards, requiring an external guide to protect the Ø5 mm rod from binding during rapid 50-800 mm/s cycles.
Small Parts Elevator
Lifts plastic trays weighing up to 5.1 kg vertically, relying on metered exhaust to prevent the fixed TPU bumpers from bottoming out under load.
Is the Airtac PB Pen-type Cylinder PB16X200U the Right Cylinder?
This 16 mm bore provides the highest standard thrust in the PB family, pushing 100.5 N at 0.5 MPa. If your application requires less force, stepping down to the 12 mm bore yields 56.5 N of push. Since 16 mm is the largest available size, there is no larger option in this series. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa figure) to account for seal friction. This equates to lifting approximately 5.1 kg vertically with a 2:1 safety margin.
A plain double-acting cylinder drifts when air pressure is lost or the valve is centered, as the internal bumpers only decelerate near stroke end rather than locking the rod. If your process requires fail-safe position holding, specify an external rod lock. When ordering, confirm the 16 mm bore, 200 mm stroke, M5x0.8 port, U 90-degree side inlet, and the absence of a sensor 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 PB16X200U 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.
The U back cover features a 90-degree perpendicular M5x0.8 air inlet for flat plumbing in tight spaces. This model uses fixed TPU bumpers at both ends to decelerate the piston near the stroke limits. These bumpers are not adjustable, so high-speed loads may require an external shock absorber.
