Airtac PB Pen-type Cylinder PB16X75SUFA
The AirTAC Airtac PB Pen-type Cylinder PB16X75SUFA is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 75mm 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 PB16X75SUFA
The AirTAC PB16X75SUFA is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive work areas. Delivering 100.5 N of push force at 0.5 MPa, it integrates a built-in piston magnet for position sensing. The U option provides a 90-degree perpendicular side air inlet for flat plumbing, while the FA bracket supplies a robust mounting interface.
Air enters via the M5x0.8 port, driving the Ø5 mm rod with its M10x1.0 end thread at speeds from 50 to 800 mm/s. End-of-stroke energy is managed by a fixed TPU bumper at each end. Because this bumper only decelerates the final few millimeters of travel, high-speed applications carrying real tooling mass require metering out the exhaust or adding an external shock absorber to prevent hard bottoming.

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 PB16X75SUFA Is Used
PCB Depaneling Router
Provides the 100.5 N extend thrust at 0.5 MPa to plunge a small routing spindle into assembled circuit boards, utilizing the FA bracket to bolt directly onto the moving carriage.
Carton Flap Folder
Actuates a lightweight folding arm to tuck minor flaps on small product boxes, taking advantage of the U 90-degree side inlet to keep air plumbing flush against the machine frame.
Sorting Diverter Gate
Pushes lightweight parcels off a transport belt using the integrated magnet for position confirmation, while the SUS304 barrel withstands washdown environments in food packing lines.
Is the Airtac PB Pen-type Cylinder PB16X75SUFA the Right Cylinder?
When sizing this 16 mm bore actuator, plan for a safe working load of roughly 60 N (about 60% of the 100.5 N theoretical push at 0.5 MPa) to account for seal friction and smooth travel. In vertical lift scenarios, this equates to lifting about 5.1 kg with a sane 2:1 safety margin. If you need less force, stepping down to the 12 mm bore yields 56.5 N push at 0.5 MPa; if you require more power, this 16 mm bore is the largest in the PB family, delivering a maximum 140.7 N push at 0.7 MPa. A plain pneumatic cylinder does not hold its load when air is lost or the valve is centered—the piston drifts, and the bumper only decelerates near stroke end, so an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 16 mm bore, 75 mm stroke, M5x0.8 port, S magnet, U side inlet, and FA mount.
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 PB16X75SUFA FAQ
This double-acting single-rod 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 and 0.7 MPa, with a proof pressure of 1.2 MPa, and travels at speeds of 50-800 mm/s.
No, a standard PB cylinder drifts when air is lost or the valve is centered, as the fixed TPU bumpers only decelerate the rod near stroke end rather than locking it. For fail-safe vertical holding, you must install an external stop or a dedicated rod lock. Additionally, the thin Ø5 mm rod is built for coaxial thrust, so over the 75 mm stroke, use an external guide to prevent side loading.
