Airtac PB Pen-type Cylinder PB16X16SU
The AirTAC Airtac PB Pen-type Cylinder PB16X16SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 16mm 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 PB16X16SU
The AirTAC PB16X16SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency tasks. It provides a robust 100.5 N push and 90.7 N pull at 0.5 MPa, driven through an M5x0.8 port. The U configuration introduces a 90-degree side air inlet, enabling flat plumbing in restricted spaces. A built-in S magnet enables position detection.
Its slim SUS304 stainless steel barrel and piston rod resist moisture in damp environments, while the Ø5 mm rod features an M10x1.0 end thread for secure load coupling. Deceleration relies on a fixed TPU bumper at each end. Because this bumper only absorbs impact over the final few millimeters, metering out the exhaust or adding an external shock absorber is advised when moving heavy tooling at high speeds.

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 PB16X16SU Is Used
PCB Depaneling Router
Actuates a cutting head fixture on an electronics assembly line, utilizing the 90-degree side inlet to keep pneumatic tubing flush against the machine frame.
Carton Flap Folder
Tucks minor flaps on a packaging conveyor, where the fixed TPU bumper effectively absorbs the repetitive impact of the 16 mm stroke cycle.
Lab Sample Dispenser
Drives a微量 pipetting arm in a wet analytical instrument, relying on the SUS304 stainless construction to prevent corrosion from reagent splashes.
Is the Airtac PB Pen-type Cylinder PB16X16SU the Right Cylinder?
Selecting this 16 mm bore yields 100.5 N of thrust at 0.5 MPa. If you need less force, the 12 mm bore steps down to 56.5 N; stepping up is not available as this is the largest diameter in the PB family. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa rating) to account for seal friction, or expect to vertically lift about 5.1 kg with a 2:1 safety margin. Remember that a plain cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required for fail-safe holding.
When ordering, confirm the 16 mm bore, 16 mm stroke, M5x0.8 port, the S magnet for reed or electronic switches, and the U 90-degree side inlet. The thin Ø5 mm rod is designed for coaxial thrust, so avoid side loads and utilize an external guide for off-axis components.
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 PB16X16SU 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.
No, a plain pen-size cylinder will drift and cannot hold a load without live pressure. The fixed TPU bumper only decelerates the piston near the end of stroke; it does not act as a locking brake. An external rod lock or mechanical stop is required for fail-safe holding.
