Airtac PB Pen-type Cylinder PB16X260SU
The AirTAC Airtac PB Pen-type Cylinder PB16X260SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 260mm 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 PB16X260SU
The AirTAC PB16X260SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while saving valuable space on light end-of-arm tooling. Delivering 100.5 N of push force at 0.5 MPa, this model is equipped with a built-in piston magnet for position sensing.
This specific configuration includes a 260 mm stroke and a U-type back cover, providing a 90-degree perpendicular air inlet for flat plumbing in confined machinery. Air connects via an M5x0.8 port, and the Ø5 mm piston rod features an M10x1.0 rod-end thread for secure load coupling. Operating at speeds from 50-800 mm/s, it relies on fixed TPU bumpers at both ends to decelerate the stroke. Because the rod is only 5 mm thick, maintaining coaxial alignment is critical over this long 260 mm extension to prevent side-load damage.

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 PB16X260SU Is Used
PCB Depaneling Router
Extends a cutting tool guide on an electronics assembly line, utilizing the 90-degree side inlet to keep pneumatic plumbing flat against the machine frame while delivering 100.5 N of push.
Package Sorting Diverter
Pushes small cartons off a logistics belt at high frequency, where the SUS304 stainless body resists humidity and the built-in magnet tracks position for the control system.
Textile Loom Take-up
Actuates a yarn tensioning lever in a weaving machine, benefiting from the 260 mm stroke and fixed TPU bumpers to manage rapid cycling speeds up to 800 mm/s.
Is the Airtac PB Pen-type Cylinder PB16X260SU the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø12 bore if you need a lighter footprint, which provides 56.5 N push at 0.5 MPa, or stepping up if your application exceeds this unit's 100.5 N push at 0.5 MPa. A practical safe working load for this model is about 60 N (roughly 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel. For vertical lifting, plan for a maximum part weight of about 5.1 kg to maintain a sane 2:1 safety margin. Remember that a plain cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, so an external rod lock is required for fail-safe holding.
To order, confirm your essentials: 16 mm bore, 260 mm stroke, M5x0.8 port, built-in magnet (S), and U-type 90-degree side inlet. The fixed TPU bumper only absorbs impact over the final few millimeters of travel; if you are moving real tooling mass at high speeds, meter-out the exhaust or install an external shock absorber to prevent bottoming out.
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 PB16X260SU FAQ
This double-acting cylinder 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 built-in -S magnet allows AirTAC reed or electronic switches to read piston position anywhere along the barrel. The U-type back cover features a 90-degree perpendicular air inlet, enabling flat plumbing in tight jigs where an axial fitting would protrude too far.
