Airtac PB Pen-type Cylinder PB16X5U
The AirTAC Airtac PB Pen-type Cylinder PB16X5U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 5mm 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 PB16X5U
The AirTAC PB16X5U is a JIS pen-size double-acting mini cylinder engineered for very short 5 mm strokes. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, driven by a 16 mm bore. The SUS304 stainless barrel and piston rod provide excellent durability in damp or mildly corrosive environments, keeping the unit slim enough for compact end-of-arm tooling.
This variant features a U-type back cover, orienting the M5x0.8 air port at 90 degrees for flat plumbing along a machine frame. Because it lacks an adjustable air cushion, it relies on a fixed TPU bumper at each end to absorb impact. For such a brief stroke, the impact energy is minimal, but the non-locking design means the piston will drift if air pressure is lost.

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 PB16X5U Is Used
Micro-Clamp Actuation
Drives a short 5 mm gripping motion in semiconductor wafer handling jigs where the 100.5 N push force securely holds delicate silicon components without crushing them.
Film Seal Tamping
Provides a rapid 5 mm tap to press thermal film against packaging trays, utilizing the flat 90-degree U inlet to keep pneumatic tubing flush with the sealing head.
Ejector Pin Stroke
Executes a quick 5 mm ejection of small molded plastic parts from a die, benefiting from the 50-800 mm/s speed range and fixed TPU bumpers to handle high-frequency cycling.
Is the Airtac PB Pen-type Cylinder PB16X5U the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N, which accounts for seal friction at 0.5 MPa. In vertical lift scenarios, this equates to raising about 5.1 kg safely with a 2:1 margin. If your application requires slightly less force, stepping down to the 12 mm bore yields 56.5 N of push at 0.5 MPa, while this 16 mm bore provides the maximum standard thrust in the family before requiring a larger profile body.
Confirm your ordering essentials: 16 mm bore, 5 mm stroke, M5x0.8 port, U-type 90-degree side inlet, and no sensor magnet. The Ø5 mm piston rod utilizes an M10x1.0 rod-end thread for load coupling. Since the rod is designed strictly for coaxial thrust, avoid side loading and add an external linear guide if the load is off-axis.
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 PB16X5U 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 range of 50-800 mm/s.
The U designation means the back cover has a 90-degree side air inlet, allowing hoses to run parallel to the barrel for tight spaces. Instead of an adjustable air cushion, it uses fixed TPU bumpers at both ends to decelerate the piston over the last few millimeters. It does not hold position on air loss, so an external rod lock is needed for fail-safe holding.
