Airtac PB Pen-type Cylinder PB16X85CB
The AirTAC Airtac PB Pen-type Cylinder PB16X85CB 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 PB16X85CB
The AirTAC PB16X85CB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers a theoretical push of 100.5 N and pull of 90.7 N at 0.5 MPa, driven through an M5x0.8 air port. The Ø5 mm piston rod features an M10x1.0 rod-end thread, providing a robust interface for coupling to your payload while maintaining a slim profile.
Built with a SUS304 stainless steel barrel and rod, this unit withstands damp or mildly corrosive environments. The CB back cover equips it with a double clevis for pivoting mountings. Deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Plan for a safe working load of roughly 60 N at 0.5 MPa to account for seal friction and smooth travel.

| 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 PB16X85CB Is Used
Package Diverter Arm
Drives a lightweight swinging gate to sort small cartons on a packaging line, utilizing the CB double clevis to accommodate the pivoting arc during stroke transitions.
PCB Test Fixture
Applies downward pressure to probe electrical contacts, where the 100.5 N output at 0.5 MPa is sufficient to compress pogo pins without damaging the delicate board substrate.
Lab Sample Handler
Pushes fluid vials into a testing carousel in wet laboratory environments, benefiting from the SUS304 stainless construction to resist ambient moisture and chemical vapors.
Is the Airtac PB Pen-type Cylinder PB16X85CB the Right Cylinder?
This 16 mm bore provides the highest thrust in the PB family. If your application requires less force, stepping down to the Ø12 model yields 56.5 N push at 0.5 MPa. Because Ø16 is the largest available, there is no larger standard option. When sizing the 85 mm stroke, confirm your porting (M5x0.8), the CB double clevis requirement, and that no position sensing is needed since this unit lacks the -S magnet.
The fixed elastomer bumpers only decelerate the piston over the final few millimeters of travel. If your tooling mass is high at cycle speeds up to 800 mm/s, meter-out the exhaust or install an external shock absorber. Furthermore, a plain cylinder drifts when air pressure is lost or the valve is centered; specify an external rod lock if the mechanism must hold position safely.
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 PB16X85CB 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 is 140.7 N and the pull is 126.9 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, a standard double-acting cylinder drifts when air is removed or the valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke ends; they do not act as a locking brake. You must add an external stop or rod lock to maintain vertical position safely.
