Airtac PB Pen-type Cylinder PB16X80SU
The AirTAC Airtac PB Pen-type Cylinder PB16X80SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 80mm 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 PB16X80SU
The AirTAC PB16X80SU is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, utilizing an M5x0.8 air port and an M10x1.0 rod-end thread to couple securely to your tooling. The SUS304 stainless barrel and piston rod resist moisture in washdown or mildly corrosive environments, while the slim round body saves valuable payload on end-of-arm robotic assemblies.
This specific configuration includes an 80 mm stroke and a U-type back cover, providing a 90-degree perpendicular air inlet for flat, space-saving plumbing along a machine frame. Equipped with a built-in magnet (-S), the piston is ready for position sensing using AirTAC reed or electronic switches. The cylinder relies on a fixed TPU bumper at each end to decelerate motion, operating efficiently at speeds between 50 and 800 mm/s.

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 PB16X80SU Is Used
PCB Depaneling Ejector
Pushes separated circuit boards off a conveyor fixture in electronics assembly, utilizing the 100.5 N extend force and compact stainless body to fit within dense routing machinery.
Carton Flap Tucking
Tucks minor flaps on small product cartons in continuous packaging lines, where the 90-degree U inlet keeps air hoses flush against the frame and the fixed TPU bumper absorbs high-frequency impacts.
Lightweight Vertical Lift
Elevates 5 kg component trays between processing stations, relying on the magnetic piston for electronic switch feedback to confirm the 80 mm stroke endpoint without external sensors.
Is the Airtac PB Pen-type Cylinder PB16X80SU the Right Cylinder?
When sizing this actuator, note that the PB16X80SU provides 100.5 N of push force at 0.5 MPa. If you need to step down for a lighter task, the adjacent 12 mm bore offers 56.5 N of push, while stepping up is not applicable as 16 mm is the largest in this pen-size family. Factoring in seal friction, plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa rating). For vertical lifts, this translates to safely raising approximately 5.1 kg with a 2:1 safety margin.
Because the U-type cover introduces a 90-degree inlet, ensure your tubing layout accommodates side-entry plumbing. The 80 mm stroke falls well within the 300 mm standard limit for this bore. Remember that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered; if your process requires fail-safe load holding, you must integrate an external stop or rod lock. The thin Ø5 mm rod is designed strictly for coaxial thrust, so add a linear bearing if the mechanism imposes any side load.
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 PB16X80SU FAQ
This double-acting cylinder generates a push of 100.5 N and a pull of 90.7 N 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 uses an M5x0.8 port.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the stroke end and does not act as a locking brake. For vertical applications requiring fail-safe holding, you must add an external rod lock or mechanical stop.
