Airtac PB Pen-type Cylinder PB16X95CB
The AirTAC Airtac PB Pen-type Cylinder PB16X95CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 95mm 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 PB16X95CB
The AirTAC PB16X95CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It utilizes a slim SUS304 stainless steel barrel and a 5mm piston rod, providing robust resistance in damp or mildly corrosive environments while keeping end-of-arm tooling weight to an absolute minimum. Delivering 100.5N of push force at 0.5MPa, it integrates a CB double clevis for pivoting loads and an M5x0.8 air port.
Because this model lacks a sensor magnet, position detection is not available out of the box. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion, meaning the last few millimeters of travel are absorbed passively. For higher approach speeds with heavy tooling mass, metering out the exhaust or fitting an external shock absorber is strongly recommended to prevent 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 PB16X95CB Is Used
Pivoting Diverter Gate
Ideal for actuating a lightweight sorting flap on a packaging conveyor, utilizing the CB double clevis to accommodate the pivot arc while pushing light cardboard cartons.
Small Part Ejection
Provides reliable thrust to eject stamped metal components from a die set, where the 100.5N output at 0.5MPa is sufficient to clear small parts without damaging the tooling.
PCB Test Fixture
Drives a probe head onto printed circuit boards in an electronics assembly jig, benefiting from the slim stainless body to fit densely packed testing arrays.
Is the Airtac PB Pen-type Cylinder PB16X95CB the Right Cylinder?
Selecting the PB16X95CB places you at the top of this mini cylinder family's standard force range. If you need slightly less thrust, stepping down to the 12mm bore yields a 56.5N push at 0.5MPa, whereas this 16mm bore provides 100.5N at the same pressure. With a 95mm stroke, the 5mm rod is somewhat slender, so maintaining coaxial thrust is critical; add an external linear bearing if the application involves any off-axis loading to prevent rod binding.
Plan for a safe working load of roughly 60N, which accounts for seal friction and smooth travel at 0.5MPa. Keep in mind that a standard pen-size body does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the bumper only decelerates near the end of the stroke. Confirm your ordering essentials: 16mm bore, 95mm stroke, M5x0.8 port, no magnet, CB double clevis back cover.
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 PB16X95CB FAQ
This 16mm bore double-acting cylinder delivers a push force of 100.5N and a pull force of 90.7N at 0.5MPa. At the maximum operating pressure of 0.7MPa, the push force is 140.7N and the pull force is 126.9N. It operates on filtered air at 0.15-0.7MPa, with a speed range of 50-800mm/s and a proof pressure of 1.2MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end and does not function as a lock or brake. For fail-safe vertical holding, an external rod lock or mechanical stop must be installed.
