Airtac PB Pen-type Cylinder PB16X75U
The AirTAC Airtac PB Pen-type Cylinder PB16X75U 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 PB16X75U
The AirTAC PB16X75U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 100.5 N of push force at 0.5 MPa, utilizing a slim SUS304 stainless steel round barrel and a 5 mm piston rod to endure damp or mildly corrosive production lines. The U option provides a 90-degree perpendicular air inlet for flat plumbing, keeping hoses tight against the machine frame.
Air enters via an M5x0.8 port to drive the 75 mm stroke, while a fixed TPU bumper at each end absorbs end-of-stroke impact. Because this bumper only decelerates the final few millimeters, high-speed cycles with heavy tooling require metering out the exhaust or adding an external shock absorber. Plan for a safe working load of roughly 60 N at 0.5 MPa to account for seal friction and smooth travel.

| Stroke | 75 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |

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 PB16X75U Is Used
Package Diverter Arm
Pushes light cardboard cartons on a packaging line, using the U side inlet to keep pneumatic hoses flush against the conveyor frame.
Lab Sample Ejector
Ejects plastic test tubes from a wet processing station, relying on the SUS304 stainless barrel to resist mild chemical splashes.
Small Parts Sorter
Extends 75 mm to deflect metal stampings into collection bins, requiring an external shock absorber if cycle speeds exceed the TPU bumper capacity.
Is the Airtac PB Pen-type Cylinder PB16X75U the Right Cylinder?
Selecting this 16 mm bore yields 100.5 N push at 0.5 MPa, sitting at the top of the PB family range; stepping down to a 12 mm bore drops the push to 56.5 N. When ordering, confirm the 75 mm stroke, M5x0.8 porting, the U 90-degree side inlet, and whether you need LB, FA, or CJ mounting brackets. The thin 5 mm rod is built for coaxial thrust, so over this 75 mm stroke you should add an external linear bearing if the load is off-axis.
A plain PB body does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the bumper cannot act as a brake. To safely suspend a vertical load, which is approximately 5.1 kg with a 2:1 margin at 0.5 MPa, you must install an external rod lock or mechanical stop.
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 PB16X75U 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, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the end of the stroke and does not function as a locking brake. An external stop or rod lock is required for fail-safe load holding.
