Airtac PB Pen-type Cylinder PB16X175U
The AirTAC Airtac PB Pen-type Cylinder PB16X175U is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 175mm 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 PB16X175U
The AirTAC PB16X175U is a double-acting JIS pen-size mini cylinder featuring a 16mm bore and 175mm stroke. It delivers 100.5 N of push force at 0.5 MPa, extending to a maximum of 140.7 N at 0.7 MPa. The SUS304 stainless barrel and piston rod provide reliable durability in damp or mildly corrosive environments, while the slim profile saves valuable space on end-of-arm tooling.
This specific configuration includes a U-type back cover, meaning the M5x0.8 air port enters at a 90-degree angle for flat plumbing against machine frames. Travel is governed by a fixed TPU bumper at each end that decelerates the piston over the final few millimeters. Because the rod is a slender Ø5 mm threaded M10x1.0, maintaining coaxial alignment is critical to prevent binding over the 175mm extension.

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 PB16X175U Is Used
Package Diverter Arm
Pushes lightweight cardboard cartons on a packaging line where the U-side inlet keeps pneumatic hoses flush against the conveyor frame.
PCB Test Fixture
Drives a probe block onto printed circuit boards, utilizing the SUS304 body to resist flux residues and cleaning chemicals.
Small Parts Elevator
Lifts plastic cassettes between processing stations, relying on the 100.5 N extend force to move loads safely under the 5.1 kg vertical threshold.
Is the Airtac PB Pen-type Cylinder PB16X175U the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 60 N at 0.5 MPa, which accounts for seal friction and smooth travel. For vertical lifts, this equates to raising about 5.1 kg with a sensible 2:1 safety margin. If you need less force, the adjacent Ø12 bore provides 56.5 N push at 0.5 MPa; stepping up is not possible as Ø16 is the largest in this series. If your process must hold a load vertically without live pressure, note that this cylinder will drift when air is lost, requiring an external rod lock.
Confirm your ordering essentials: 16mm bore, 175mm stroke, M5x0.8 porting, no sensor magnet, and the U 90-degree side inlet. The fixed bumpers are not adjustable, so if you move heavy tooling mass at high speed, meter-out the exhaust or add an external shock absorber to prevent end-cap impact.
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 PB16X175U 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.
The U back cover provides a 90-degree side air inlet for flat plumbing in confined spaces. End-of-stroke deceleration is handled by fixed TPU bumpers, which are not field-adjustable. For high-speed or heavy tooling, you should meter-out the exhaust or add an external shock absorber to avoid bottoming out the bumper.
