Airtac PB Pen-type Cylinder PB16X190SU
The AirTAC Airtac PB Pen-type Cylinder PB16X190SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 190mm 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 PB16X190SU
The AirTAC PB16X190SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It supplies 100.5 N of push and 90.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and piston rod to resist damp or mildly corrosive environments. This model includes a built-in piston magnet for position detection and features a U-type 90-degree side air inlet for flat plumbing in confined spaces.
Equipped with a fixed TPU bumper at each end, the unit decelerates the piston over the final few millimeters of travel rather than providing an adjustable air cushion. The M5x0.8 port and M10x1.0 rod-end thread ensure straightforward integration. Because the rod is a slender Ø5 mm, maintaining coaxial thrust is essential to prevent binding over the 190 mm stroke.

| 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 PB16X190SU Is Used
PCB Depaneling Router
Pushes a light carrier plate against a fixed fence on an electronics assembly line, using the 90-degree U inlet to keep plumbing flush against the machine frame.
Carton Flap Folder
Folds minor corrugated flaps prior to tape sealing, where the SUS304 body withstands occasional washdowns and the 100.5 N output easily overcomes board stiffness.
Pallet Diverter Gate
Actuates a lightweight routing flap to sort small product to a secondary lane, relying on the built-in S magnet to confirm gate position via a reed or electronic switch.
Is the Airtac PB Pen-type Cylinder PB16X190SU the Right Cylinder?
When sizing this actuator, stepping down to the Ø12 bore yields 56.5 N of push at 0.5 MPa, while stepping up is not available as Ø16 is the largest in this series. Plan for a safe working load of roughly 60 N (about 60% of the 100.5 N theoretical force) to account for seal friction and smooth travel. For vertical lifts, this equates to raising approximately 5.1 kg safely with a 2:1 margin.
A plain double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and an external stop or rod lock is required for fail-safe holding. To order, confirm the 16 mm bore, 190 mm stroke, M5x0.8 port, S magnet, and U 90-degree side inlet. The fixed bumper is not adjustable, so metering out the exhaust or adding an external shock absorber is recommended when moving heavy tooling at high speeds.
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 PB16X190SU 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 speed range of 50-800 mm/s.
No, a standard double-acting cylinder drifts when air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the end of stroke and does not act as a brake. An external rod lock or mechanical stop is required to hold loads safely.
