About the Airtac PB Pen-type Cylinder PB12X180SR
The AirTAC PB12X180SR is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while saving valuable space on light end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, it provides reliable thrust for small part handling.
This 12mm bore model includes an integrated piston magnet (S) for position sensing via AirTAC reed or electronic switches, and an R axial air inlet for in-line plumbing. The M5x0.8 port and M10x1.0 rod-end thread ensure secure connections. It operates at speeds from 50-800 mm/s and relies on a fixed TPU bumper at each end to decelerate the stroke.

| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 180 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) |

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 PB12X180SR Is Used
PCB Depaneling Router
Extends a light cutting probe along a 180mm path to singulate circuit boards, utilizing the slim stainless body to fit within dense electronics manufacturing fixtures.
Package Sorting Diverter
Pushes small parcels on a distribution line where the 56.5 N output at 0.5 MPa easily redirects lightweight boxes without consuming valuable conveyor frame space.
Lab Sample Dispenser
Drives a pipetting head down into reagent trays, benefiting from the S magnet for electronic switch position confirmation and the compact profile for multi-head arrays.
Is the Airtac PB Pen-type Cylinder PB12X180SR the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø10 bore if your payload is lighter, which yields 39.3 N push at 0.5 MPa, or stepping up to the Ø16 bore for heavier tasks providing 100.5 N push.
With a 180mm stroke, the thin Ø5 mm piston rod is built for coaxial thrust and requires an external guide or linear bearing if subjected to off-axis loads to prevent binding. Note that a plain cylinder does not hold its position if air pressure is lost; the piston will drift, so an external rod lock is required for fail-safe holding. Ensure your order specifies the 12mm bore, 180mm stroke, S magnet, R axial inlet, and M5x0.8 port.
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 PB12X180SR FAQ
This 12mm bore double-acting cylinder provides 56.5 N push and 46.7 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 79.1 N push and 65.4 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
It uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not an adjustable air cushion or a locking brake. Because it does not hold position on air loss, you must add an external rod lock for fail-safe holding, and at high speeds with real mass, consider metering out the exhaust.
