Airtac PB Pen-type Cylinder PB16X230SU
The AirTAC Airtac PB Pen-type Cylinder PB16X230SU is a double-acting pen-size (mini) air cylinder with a Ø16mm bore and 230mm 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 PB16X230SU
The AirTAC PB16X230SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. At 16mm bore, it generates 100.5 N of push force and 90.7 N of pull force at 0.5 MPa.
This specific configuration includes a built-in piston magnet (-S) for position sensing and a U-type back cover providing a 90-degree side air inlet for flat plumbing. Air connects via an M5x0.8 port, and the rod-end features an M10x1.0 thread. Travel is capped by a fixed TPU bumper at each end, which decelerates the piston over the final few millimeters rather than providing a rigid lock.

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 PB16X230SU Is Used
PCB Depaneling Router
Pushes a lightweight carrier jig through a routing spindle on an electronics assembly line, utilizing the 90-degree side inlet to keep plumbing flush against the machine frame.
Package Sorting Diverter
Extends a paddle to deflect small cartons on a logistics conveyor, where the fixed TPU bumper absorbs the repeated impact of the 230mm stroke at high cycling speeds.
Lab Sample Dispenser
Actuates a dispensing probe into reagent trays, benefiting from the SUS304 stainless construction to resist chemical moisture and the integrated magnet for precise position confirmation.
Is the Airtac PB Pen-type Cylinder PB16X230SU the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 60 N, which accounts for roughly 60% of the 100.5 N theoretical push at 0.5 MPa to overcome seal friction and ensure smooth travel. For vertical lifts, this translates to safely raising around 5.1 kg with a 2:1 safety margin. If you need less force, stepping down to the 12mm bore yields 56.5 N push at 0.5 MPa; if you require more power, this 16mm bore is the largest in the PB family, delivering the maximum 140.7 N at 0.7 MPa.
Because the 230mm stroke is relatively long for the slender Ø5 mm rod, adding an external linear guide is recommended to prevent side-loading and buckling. Note that a plain double-acting cylinder drifts when air pressure is lost or the valve is centered, so an external rod lock is required for fail-safe load holding. Confirm your ordering essentials: 16mm bore, 230mm stroke, M5x0.8 port, S magnet, U side inlet, and no mounting bracket.
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 PB16X230SU 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 of 50-800 mm/s and a proof pressure of 1.2 MPa.
The -S suffix denotes a built-in piston magnet compatible with AirTAC reed or electronic switches for non-contact position detection. Cushioning is handled by a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not adjustable, so external shock absorbers or meter-out flow controls are advised for heavy tooling masses.
