Airtac PB Pen-type Cylinder PB16X90CB
The AirTAC Airtac PB Pen-type Cylinder PB16X90CB is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 90mm 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 PB16X90CB
The AirTAC PB16X90CB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers a robust 100.5 N push and 90.7 N pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to resist damp or mildly corrosive environments. The CB suffix equips the rear cover with a double clevis, providing a pivoting anchor point ideal for articulating mechanisms.
Air enters via an M5x0.8 port, driving the 5 mm rod at speeds from 50 to 800 mm/s. End-of-stroke energy is managed by fixed TPU bumpers rather than adjustable air cushions, decelerating the piston over the final few millimeters. For an application moving real tooling mass at high speeds, metering out the exhaust or adding an external shock absorber prevents the bumpers from bottoming out harshly.

| 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 PB16X90CB Is Used
Textile Loom Deflection
Actuates thread guide arms on weaving machinery where the CB double clevis accommodates the pivot arc during high-speed loom cycling.
Carton Flap Folding
Drives a lightweight folding blade to tuck corrugated box flaps prior to tape sealing, fitting neatly within tight conveyor side frames.
PCB Tray Elevation
Raises empty printed circuit board trays from a lower magazine slot, lifting approximately 4 kg of tray weight smoothly via the 5 mm stainless rod.
Is the Airtac PB Pen-type Cylinder PB16X90CB the Right Cylinder?
Selecting this 16 mm bore yields 100.5 N of theoretical thrust at 0.5 MPa. Accounting for seal friction, a safe working load is roughly 60 N (about 60% of the 0.5 MPa figure). In vertical lift scenarios, this translates to safely raising around 5.1 kg with a sane 2:1 margin. If your task requires less force, stepping down to the 12 mm bore provides 56.5 N push at 0.5 MPa; since 16 mm is the largest in this series, moving beyond 140.7 N maximum push requires a larger profile body entirely.
When ordering, confirm the 16 mm bore, 90 mm stroke, M5x0.8 port, and the CB double clevis. Note that a plain PB cylinder drifts when air pressure is lost or the valve is centered, as the bumpers only decelerate near stroke end rather than locking the load. For fail-safe holding, an external rod lock or mechanical stop is required.
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 PB16X90CB FAQ
At 0.5 MPa, the push (extend) force is 100.5 N and the pull (retract) 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 CB suffix indicates a rear double clevis that allows the cylinder body to pivot during the stroke, accommodating lateral load movement. End cushioning relies on fixed TPU bumpers rather than adjustable air cushions, meaning they only decelerate the last few millimeters of travel and cannot be field-tuned.
