Airtac PB Pen-type Cylinder PB16X160U
The AirTAC Airtac PB Pen-type Cylinder PB16X160U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 160mm 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 PB16X160U
The AirTAC PB16X160U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments. Delivering 100.5 N of push force at 0.5 MPa, it provides robust thrust for its footprint while keeping end-of-arm tooling lightweight.
This 16 mm bore, 160 mm stroke variant uses an M5x0.8 port and a U-type back cover that introduces a 90-degree perpendicular air inlet for flat plumbing in confined spaces. It relies on a fixed TPU elastic bumper at each end to decelerate the stroke, and because there is no -S suffix, it ships without a sensor magnet.

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 PB16X160U Is Used
PCB Depaneling Router
Drives a light cutting head along a 160 mm path to singulate circuit boards, utilizing the 90-degree side inlet to keep pneumatic plumbing flush against the machine frame.
Carton Flap Folder
Extends to tuck small corrugated flaps during case erecting, where the fixed TPU bumper absorbs the end-of-stroke impact and the SUS304 barrel resists humid packing room air.
Vertical Part Lift
Elevates delicate electronic connectors between conveyor tiers, safely lifting a payload of about 5.1 kg vertically with a 2:1 force margin at 0.5 MPa.
Is the Airtac PB Pen-type Cylinder PB16X160U the Right Cylinder?
When sizing this actuator, note the Ø12 bore steps down to 56.5 N push at 0.5 MPa, while this Ø16 provides 100.5 N at the same pressure. As the largest bore in the PB family, there is no larger step up, making it the maximum thrust option here. For real-world work, plan for a safe working load of about 60 N (roughly 60% of the 0.5 MPa figure) to account for seal friction and smooth travel.
The thin Ø5 mm piston rod with an M10x1.0 end thread is designed strictly for coaxial thrust over its 160 mm stroke, so add an external guide or linear bearing if the load is off-axis. Because a plain PB body lacks a locking mechanism, the piston will drift if air pressure drops or the valve is centered, requiring an external stop or rod lock for fail-safe position holding. Confirm your ordering essentials: 16 mm bore, 160 mm stroke, M5x0.8 porting, no magnet, and the U 90-degree side inlet.
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 PB16X160U FAQ
The 16 mm bore generates 100.5 N push and 90.7 N pull at 0.5 MPa. 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 U back cover provides a 90-degree perpendicular air inlet for flat plumbing in tight jigs. Instead of an adjustable air cushion, it uses a fixed TPU bumper at each end that only decelerates the last few millimeters of travel. For high-speed or heavy tooling mass, meter-out the exhaust or add an external shock absorber to prevent bottoming out.
