Airtac PB Pen-type Cylinder PB16X85SCB
The AirTAC Airtac PB Pen-type Cylinder PB16X85SCB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 85mm 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 PB16X85SCB
The AirTAC PB16X85SCB is a JIS pen-size double-acting mini cylinder engineered for compact automation. 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 under the family maximum 0.7 MPa operating pressure. The SUS304 stainless barrel and slim round profile reduce payload on end-of-arm tooling, fitting easily into tight jig spaces. Air connects via an M5x0.8 port, driving a 5 mm rod with an M10x1.0 end thread.
This specific configuration includes an integrated piston magnet for position sensing with AirTAC reed or electronic switches. The CB suffix denotes a double clevis back cover, providing a pivoting mount for articulating loads. End-of-stroke deceleration relies on a fixed TPU bumper at each end, which absorbs impact over the final few millimeters rather than providing an adjustable air cushion.

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 PB16X85SCB Is Used
PCB Depaneling Router
Actuates a cutting head fixture on an electronics assembly line, utilizing the 100.5 N push force to separate routed circuit panels cleanly.
Carton Flap Folder
Pivots via the CB clevis to fold minor corrugated box flaps prior to taping, fitting within the narrow frame of a packaging sealer.
Lab Tube Ejector
Pushes racked centrifuge tubes out of a centrifuge carousel, using the integrated S magnet to confirm ejection via a solid-state switch.
Is the Airtac PB Pen-type Cylinder PB16X85SCB the Right Cylinder?
Selecting this 16 mm bore provides the highest thrust in the PB family. If your application requires less force, stepping down to the 12 mm bore yields 56.5 N push at 0.5 MPa, while this 16 mm unit provides 100.5 N at the same pressure. Plan for a safe working load of roughly 60 N, accounting for seal friction and smooth travel at 0.5 MPa. For vertical lifts, this equates to raising about 5.1 kg safely with a 2:1 margin.
Because the CB double clevis allows pivoting, ensure the rod remains coaxial to avoid side loading the 5 mm rod. Note that this cylinder will not hold a load if air pressure drops or the valve is centered; the piston will drift, and an external rod lock is required for fail-safe holding. Confirm your ordering essentials: 16 mm bore, 85 mm stroke, M5x0.8 port, S magnet, and 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 PB16X85SCB 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 cylinder operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
The CB double clevis allows the cylinder to pivot with the load. Deceleration is handled by a fixed TPU bumper at each end that absorbs energy over the final few millimeters of travel. It is not an adjustable air cushion, so at high speeds with heavy tooling mass, you should meter-out the exhaust or add an external shock absorber.
