Airtac PB Pen-type Cylinder PB16X90U
The AirTAC Airtac PB Pen-type Cylinder PB16X90U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 90mm 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 PB16X90U
The AirTAC PB16X90U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 100.5 N of push and 90.7 N of pull at 0.5 MPa, peaking at 140.7 N extend force under the 0.7 MPa maximum operating pressure. The SUS304 stainless barrel and rod resist moisture in damp work areas, while the slim profile saves payload on light end-of-arm tooling.
This specific configuration includes a U-type back cover, providing a 90-degree perpendicular air inlet for flat plumbing along a machine frame. Air connects via an M5x0.8 port, and the load fastens to an M10x1.0 rod-end thread. Deceleration relies on a fixed TPU bumper at each end, which absorbs impact over the final few millimeters of travel rather than providing adjustable cushioning.

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 PB16X90U Is Used
PCB Depaneling Router
Actuates a tooling pin to secure circuit boards during routing, utilizing the 90-degree side inlet to keep pneumatic hoses flush against the crowded machine chassis.
Blister Pack Sealing
Cycles a small heated platen at high frequency, where the fixed TPU bumpers absorb end-of-stroke impact and the stainless body resists humid packaging environments.
Sorting Diverter Arm
Pushes lightweight parcels on a distribution line, delivering a safe 60 N working force while the slim barrel fits neatly between adjacent conveyor belts.
Is the Airtac PB Pen-type Cylinder PB16X90U the Right Cylinder?
Selecting this 16 mm bore yields a practical safe working load of roughly 60 N, calculated at a 60 percent efficiency margin of the 100.5 N theoretical push at 0.5 MPa. For vertical lifts, this translates to hoisting about 5.1 kg safely with a 2:1 dynamic margin. If your process requires less force, stepping down to the 12 mm bore provides 56.5 N push at 0.5 MPa; if you need substantially more thrust, you would move beyond this pen-size family. When ordering, confirm the 90 mm stroke, the U side-inlet cover, and your required mounting brackets.
Because the thin Ø5 mm piston rod handles coaxial thrust rather than side load, adding an external guide or linear bearing is recommended for off-axis forces over the 90 mm stroke. Furthermore, a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, so integrate an external rod lock if the application demands fail-safe position holding.
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 PB16X90U FAQ
At 0.5 MPa, this double-acting cylinder provides 100.5 N push and 90.7 N pull. 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 range of 50-800 mm/s.
The U option designates a 90-degree perpendicular side air inlet, allowing flat plumbing in tight spaces. Both ends use a fixed TPU bumper to decelerate the piston near stroke end; it is not adjustable, so for heavy tooling mass at high speeds you should meter-out the exhaust or add an external shock absorber.
