Airtac PB Pen-type Cylinder PB16X200CB
The AirTAC Airtac PB Pen-type Cylinder PB16X200CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 200mm 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 PB16X200CB
The AirTAC PB16X200CB is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency motion. It utilizes a slim SUS304 stainless steel round barrel and piston rod, offering robust resistance in damp or mildly corrosive environments while keeping end-of-arm tooling exceptionally light. Delivering 100.5 N of push force at 0.5 MPa, it provides substantial thrust within a tiny footprint.
This 16 mm bore unit features an M5x0.8 air port and an M10x1.0 rod-end thread for secure load coupling. Because it carries the CB double clevis back cover, it is purpose-built for pivoting loads. The cylinder relies on a fixed TPU bumper at each end to decelerate travel over the final few millimeters; it is not an adjustable air cushion, so metering out the exhaust or adding an external shock absorber is advised when moving heavy tooling at high speeds.

| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |

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 PB16X200CB Is Used
Diverter Flap Actuation
Swings lightweight sorting gates on packaging conveyors using the CB double clevis to accommodate the pivoting arc during high-speed product routing.
Lab Sample Ejection
Pushes processed test tubes or vials out of centrifuge carousels, where the SUS304 barrel withstands frequent chemical wipe-downs and moisture.
Strip Feed Indexing
Drives small pitch advancement on thin metal strip feeders, providing 100.5 N of extend force at 0.5 MPa to advance material without adding bulk to the die jig.
Is the Airtac PB Pen-type Cylinder PB16X200CB the Right Cylinder?
When sizing this model, stepping down to a 12 mm bore yields 56.5 N of push at 0.5 MPa, while stepping up is not available as 16 mm is the largest in this family. A practical safe working load is roughly 60 N (about 60% of the 100.5 N theoretical figure at 0.5 MPa) to account for seal friction and smooth travel. For vertical lifts, plan for a maximum part weight of about 5.1 kg to maintain a sane 2:1 safety margin.
With a 200 mm stroke, the Ø5 mm piston rod is highly slender and intended purely for coaxial thrust; avoid side loading and add an external linear bearing if the payload risks off-axis force. Note that a plain PB body does not hold its position if air pressure drops or the valve is centered—the piston will drift, so an external rod lock is required for fail-safe holding. To order, confirm the 16 mm bore, 200 mm stroke, M5x0.8 porting, lack of a sensor magnet, and the CB clevis mount.
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 PB16X200CB FAQ
At 0.5 MPa, the push force is 100.5 N and the pull force is 90.7 N. At the maximum operating pressure of 0.7 MPa, the push force is 140.7 N and the pull force is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
No, a plain PB cylinder will drift if air is lost or the valve is centered, as the fixed TPU bumper only decelerates the piston near the stroke end and does not act as a lock. For fail-safe vertical holding, you must install an external rod lock or mechanical stop.
