Airtac PB Pen-type Cylinder PB16X5CB
The AirTAC Airtac PB Pen-type Cylinder PB16X5CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 5mm 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 PB16X5CB
The AirTAC PB16X5CB is a JIS pen-size double-acting single-rod mini cylinder engineered for short-stroke clamping and ejection. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a 16 mm bore and a brief 5 mm stroke. The CB suffix equips the rear cover with a double clevis, allowing the body to pivot smoothly during operation. Its slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight.
Air enters via an M5x0.8 port, driving the 5 mm rod at speeds from 50 to 800 mm/s. Because this model lacks an adjustable air cushion, it relies on a fixed TPU bumper at each end to absorb impact. For this short 5 mm travel, the bumper handles the energy well, but if you push heavier masses at high velocities, metering out the exhaust or adding an external shock absorber is recommended. This unit ships without a sensor magnet, so position detection requires external physical stops.

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 PB16X5CB Is Used
Short-Stroke Part Ejection
Kicks small plastic molded parts out of an injection press cavity using a rapid 5 mm tap, leveraging the 140.7 N maximum push to break the vacuum grip.
Pivoting Diverter Gate
Swings a lightweight sorting flap on a packaging conveyor via the CB double clevis, utilizing the brief stroke to nudge items into a secondary lane.
Clamp Actuation
Snaps a small pneumatic clamp down onto aluminum extrusions in an assembly fixture, providing firm holding pressure without consuming valuable jig space.
Is the Airtac PB Pen-type Cylinder PB16X5CB the Right Cylinder?
Selecting the PB16X5CB makes sense when your mechanism requires maximum thrust in a compact footprint. This 16 mm bore generates 100.5 N of extend force at 0.5 MPa, yielding a safe working load of about 60 N for smooth travel. If you need to step down, the 12 mm bore offers 56.5 N push, while stepping up is not available as 16 mm is the largest in this series. Keep in mind a plain PB cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required for fail-safe load holding.
When ordering, confirm the 16 mm bore, 5 mm stroke, M5x0.8 porting, and the CB double clevis rear mount. The Ø5 mm piston rod features an M10x1.0 rod-end thread for secure load coupling; ensure your linkage stays coaxial to avoid side-loading the slender rod. This configuration does not include the S option, meaning no internal magnet is present for 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 PB16X5CB 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, it yields 140.7 N push and 126.9 N pull. It operates between 0.15 and 0.7 MPa, with a speed range of 50-800 mm/s and a proof pressure of 1.2 MPa.
No, a plain PB cylinder will drift if air is lost or the valve is centered. The fixed TPU bumpers only decelerate the piston near the stroke end; they do not act as a brake. For vertical or fail-safe holding, you must add an external rod lock or mechanical stop.
