Airtac PB Pen-type Cylinder PB16X300CB
The AirTAC Airtac PB Pen-type Cylinder PB16X300CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 300mm 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 PB16X300CB
The AirTAC PB16X300CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling lightweight. At its maximum 0.7 MPa operating pressure, this 16 mm bore unit generates 140.7 N of push force and 126.9 N of pull force, with a practical safe working load around 60 N at 0.5 MPa to account for seal friction.
This specific configuration includes a CB double clevis back cover, allowing the body to pivot smoothly on a pin mount. Air plumbing connects via an M5x0.8 port, and the rod end utilizes an M10x1.0 thread for secure load coupling. Because it lacks a sensor magnet, position detection is not supported without external hardware. The Ø6-Ø16 bore range relies on a fixed TPU bumper at each end to decelerate the stroke, which is not field-adjustable.

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 PB16X300CB Is Used
Package Diverter Arm
Actuates a lightweight swinging gate to sort small cartons on a packaging line, utilizing the CB clevis to accommodate the pivoting arc of the load.
Textile Yarn Guide
Traverses a thread guide across a winding spool at high speed, where the SUS304 barrel resists humid dye-house conditions and the slim body saves space.
Thin Film Lifter
Raises and lowers a vacuum cup to pick delicate plastic films, operating within a 60 N safe load limit to prevent tearing the material during extension.
Is the Airtac PB Pen-type Cylinder PB16X300CB the Right Cylinder?
Choosing this 16 mm bore with a 300 mm stroke places you at the maximum standard extension for the series. If you need slightly less push force, stepping down to the 12 mm bore yields 56.5 N at 0.5 MPa. Since 16 mm is the largest available diameter in this family, there is no larger option; if your application requires more thrust, a different cylinder profile entirely would be necessary. For sizing real work, plan for approximately 60 N of usable force at 0.5 MPa, which equates to lifting about 5.1 kg vertically with a sane 2:1 safety margin.
When ordering, verify your requirements for the 16 mm bore, 300 mm stroke, M5x0.8 air port, and the CB double clevis pivot mount. Keep in mind that a plain PB-type cylinder does not hold its load if air pressure is lost or the valve is centered; the piston will drift, and the fixed bumper only decelerates it near the end of travel. For fail-safe holding, an external stop or rod lock is required. Additionally, the Ø5 mm piston rod is designed for coaxial thrust; over this long 300 mm stroke, adding an external guide or linear bearing is highly recommended to prevent side-loading damage.
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 PB16X300CB FAQ
This 16 mm bore double-acting cylinder provides 100.5 N push and 90.7 N pull at 0.5 MPa, reaching maximums of 140.7 N push and 126.9 N pull at the 0.7 MPa pressure limit. It operates at speeds between 50-800 mm/s, uses an M5x0.8 port, and has a fixed TPU bumper at both ends.
No, the piston will drift downward if air is lost or the directional valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke ends and do not act as a locking brake. An external rod lock or mechanical stop is necessary for fail-safe position holding.
