Airtac PB Pen-type Cylinder PB16X230SR
The AirTAC Airtac PB Pen-type Cylinder PB16X230SR 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 PB16X230SR
The AirTAC PB16X230SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It generates 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. The R axial air inlet provides clean in-line plumbing, while the M5x0.8 port and M10x1.0 rod-end thread ensure secure load coupling.
Equipped with a built-in magnet (-S), this unit supports AirTAC reed or electronic switches for precise position detection. Because the stroke extends to 230 mm, the fixed TPU bumper at each end only decelerates the final few millimeters of travel. For heavier tooling mass at high speeds, metering out the exhaust or adding an external shock absorber is strongly advised to prevent bottoming out.

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 PB16X230SR Is Used
PCB Depaneling Routing
Drives a lightweight routing tool along a 230 mm path to separate printed circuit boards, utilizing the 100.5 N push force to maintain steady feed without stressing the slim stainless barrel.
Package Sorting Diverter
Extends a narrow paddle at 50-800 mm/s to deflect small cartons on a packaging line, where the compact pen-size body fits between tight conveyor belts and the -S magnet confirms stroke completion.
Lab Sample Indexing
Shifts a sample tray carriage across a 230 mm stroke in analytical equipment, benefiting from the SUS304 construction that withstands humid or mildly corrosive laboratory conditions.
Is the Airtac PB Pen-type Cylinder PB16X230SR the Right Cylinder?
When sizing this 16 mm bore actuator, stepping down to the Ø12 variant yields 56.5 N of push at 0.5 MPa, whereas this model provides 100.5 N. It represents the largest bore in the PB family, so no larger standard option exists within the series. Plan for a safe working load of roughly 60 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel. In vertical lift scenarios, this equates to lifting about 5.1 kg with a sane 2:1 safety margin.
Note that a plain PB cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the bumper only decelerates near the stroke end. For fail-safe holding, an external stop or rod lock is required. Confirm your ordering essentials: 16 mm bore, 230 mm stroke, M5x0.8 port, S magnet, R axial inlet, and no additional 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 PB16X230SR 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 ranges from 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, a plain PB cylinder does not hold its load when air is lost or the valve is centered; the piston drifts and the fixed TPU bumper only decelerates it near the stroke end. For vertical applications requiring fail-safe holding, you must add an external stop or rod lock. Additionally, the thin Ø5 mm rod is designed for coaxial thrust, so over the 230 mm stroke, use an external guide or linear bearing to prevent side-load damage.
