Airtac PB Pen-type Cylinder PB12X160R
The AirTAC Airtac PB Pen-type Cylinder PB12X160R is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 160mm 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 PB12X160R
The AirTAC PB12X160R is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering reliable durability in damp or mildly corrosive work areas. Delivering 56.5 N of push force at 0.5 MPa, it utilizes an M5x0.8 air port and an M10x1.0 rod-end thread to couple securely with your payload.
This 12mm bore, 160mm stroke variant uses an R axial inlet for in-line plumbing. It relies on fixed TPU bumpers at both ends for end-of-stroke deceleration rather than adjustable air cushions. Because the rod is a slender Ø5 mm, maintaining coaxial thrust is critical over this longer stroke—avoid side loads or add an external linear bearing to prevent binding.

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 160 mm |
| 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 |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |
| Cushion | Elastic bumper (both ends) |
| Max standard stroke | Up to 300 mm |
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 (Ø12mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 56.5 N | 46.7 N |
| 0.7 MPa (max) | 79.1 N | 65.4 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 PB12X160R Is Used
PCB Depaneling Router
Actuates a cutting head guide on an electronics depaneling machine, where the slim stainless body resists flux residue and fits within tight router enclosures.
Carton Flap Folder
Tucks minor flaps on a small-case packaging line, using the 160mm stroke to clear varying box heights before the tape head seals the major flaps.
Lab Sample Dispenser
Drives a pipette plunger for chemical dispensing, benefiting from the fast 50-800 mm/s cycle speed and compact footprint to fit inside fume hoods.
Is the Airtac PB Pen-type Cylinder PB12X160R the Right Cylinder?
If you need less force, the Ø10 bore provides 39.3 N push at 0.5 MPa; stepping up to the Ø16 bore yields 100.5 N push at 0.5 MPa for heavier tooling.
A plain PB cylinder does not hold its position if air pressure drops or the valve is centered—the piston will drift, and the bumper only decelerates near the stroke end, so install an external rod lock for fail-safe holding. To order, confirm the 12mm bore, 160mm stroke, M5x0.8 port, no magnet, and the R axial back cover inlet.
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 PB12X160R FAQ
At 0.5 MPa, the push force is 56.5 N and the pull force is 46.7 N. At the maximum operating pressure of 0.7 MPa, the push force is 79.1 N and the pull force is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed 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. An external stop or rod lock is required for fail-safe holding.
