Airtac PB Pen-type Cylinder PB16X80CB
The AirTAC Airtac PB Pen-type Cylinder PB16X80CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 80mm 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 PB16X80CB
The AirTAC PB16X80CB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It generates 100.5 N of push force and 90.7 N of pull force at 0.5 MPa, peaking at 140.7 N push and 126.9 N pull at its 0.7 MPa maximum. The slim SUS304 stainless barrel and screwed-in covers provide excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling light.
Plumbed via an M5x0.8 port, this 16 mm bore unit travels an 80 mm stroke on a Ø5 mm stainless rod with an M10x1.0 rod-end thread. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion, meaning it only absorbs impact over the final few millimeters. The CB suffix equips the back cover with a double clevis for pivoting loads, and because there is no -S code, it lacks a sensor magnet.

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 PB16X80CB Is Used
Textile Loom Guide
Actuates a pivoting yarn guide arm on a weaving machine, utilizing the CB double clevis to accommodate the swing arc while pushing light thread tensioning components.
Carton Flap Folder
Drives a mechanical linkage to fold minor flaps on a packaging line, where the fixed TPU bumper safely absorbs the repetitive end-of-stroke impact at high cycling speeds.
Sorting Diverter Arm
Pivots a lightweight diverter gate to route small parcels on a conveyor belt, benefiting from the SUS304 stainless build to resist humidity in distribution hubs.
Is the Airtac PB Pen-type Cylinder PB16X80CB the Right Cylinder?
When sizing this unit, stepping down to the Ø12 bore yields 56.5 N push at 0.5 MPa, while stepping up is not an option as Ø16 is the largest in this family. Plan for a safe working load of roughly 60 N (about 60% of the 100.5 N @0.5 MPa figure) to account for seal friction, which translates to lifting about 5.1 kg vertically with a 2:1 safety margin. Because the thin Ø5 mm rod is built for coaxial thrust, adding an external guide or linear bearing is recommended if side loads are present.
Remember that a plain PB cylinder drifts when air pressure is lost or the valve is centered, as the TPU bumper only decelerates near stroke end rather than locking the load, so an external rod lock is needed for fail-safe holding. To order, confirm the 16 mm bore, 80 mm stroke, M5x0.8 porting, CB double clevis back cover, and the absence of a magnet.
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 PB16X80CB FAQ
This double-acting cylinder delivers 100.5 N push and 90.7 N pull at 0.5 MPa, with maximums of 140.7 N push and 126.9 N pull at 0.7 MPa. It operates at 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The CB back cover provides a double clevis pin joint ideal for pivoting linkages. Impact absorption is handled by a fixed, non-adjustable TPU bumper at each end that decelerates the piston over the final few millimeters; for heavy tooling mass at high speeds, meter-out the exhaust or add an external shock absorber.
