Airtac PB Pen-type Cylinder PB16X175R
The AirTAC Airtac PB Pen-type Cylinder PB16X175R 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 PB16X175R
The AirTAC PB16X175R 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 a 5 mm piston rod, yielding a theoretical push force of 100.5 N at 0.5 MPa (extending to 140.7 N at the 0.7 MPa maximum). The R suffix designates an axial air inlet, facilitating straight, in-line plumbing on your manifold. Air connections use an M5x0.8 port.
Because the stroke extends to 175 mm, the slender 5 mm rod requires strict coaxial alignment to prevent side-loading damage; adding an external linear bearing is recommended for off-axis loads. End-of-stroke energy is managed by a fixed TPU bumper at each end, which decelerates the piston over the final few millimeters. For higher cycling speeds with heavy tooling, metering out the exhaust or adding an external shock absorber will prevent the bumper from bottoming out.

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 PB16X175R Is Used
PCB Depaneling Router
Actuates a cutting head or clamping jaw in compact electronics manufacturing equipment where the slim 16 mm barrel saves valuable tooling space.
Carton Flap Folder
Folds minor flaps on small packaging lines, utilizing the 100.5 N extend force to overcome board stiffness while fitting within tight conveyor side frames.
Lab Sample Dispenser
Drives a pipetting or dosing head in analytical instruments, benefiting from the SUS304 construction for damp or mildly corrosive laboratory environments.
Is the Airtac PB Pen-type Cylinder PB16X175R the Right Cylinder?
This 16 mm bore provides the highest thrust in the PB family, pushing 100.5 N at 0.5 MPa. If you need a lighter touch, stepping down to the 12 mm bore yields 56.5 N of push force. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa rating) to account for seal friction, or expect to vertically lift around 5.1 kg with a sane 2:1 safety margin. A plain double-acting cylinder like this drifts when air pressure is lost or the valve is centered, so fit an external rod lock if your process demands fail-safe position holding.
When ordering, confirm the 16 mm bore, 175 mm stroke, M5x0.8 porting, and the R axial inlet configuration. This specific SKU does not include a sensor magnet; if your application requires position feedback, select an S-suffixed variant to accept AirTAC reed or electronic switches.
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 PB16X175R FAQ
This double-acting cylinder delivers a push force of 100.5 N and a pull force of 90.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it pushes 140.7 N and pulls 126.9 N. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
It relies on a fixed TPU bumper at each end to decelerate the piston over the last few millimeters, which is not adjustable. If cycling rapidly with real tooling mass, you should meter-out the exhaust or add an external shock absorber. It does not hold its load on air loss; an external stop is required for fail-safe holding.
