Airtac PB Pen-type Cylinder PB12X225SU
The AirTAC Airtac PB Pen-type Cylinder PB12X225SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 225mm 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 PB12X225SU
The AirTAC PB12X225SU 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 saving valuable space on light end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, this unit is configured with a built-in magnet for position sensing and a U-type 90-degree side air inlet for flat plumbing.
Because the 225 mm stroke exceeds the 200 mm standard maximum for a 12 mm bore, this specific model is a non-standard, made-to-order configuration. The M5x0.8 port and M10x1.0 rod-end thread are fixed by the bore size. It relies on a fixed TPU bumper at each end for end-of-stroke deceleration rather than an adjustable air cushion, operating efficiently at speeds between 50 and 800 mm/s.

| 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 (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 PB12X225SU Is Used
PCB Depaneling Router
Drives a light cutting head across a 225 mm span on an electronics assembly line, utilizing the 56.5 N push force and slim profile to navigate tight fixture clearances.
Package Sorting Diverter
Extends a lightweight paddle to deflect small cartons on a logistics belt, taking advantage of the flat U-type side inlet to keep plumbing close to the machine frame.
Lab Sample Dispenser
Actuates a fluid nozzle for precise reagent dosing in wet laboratory environments, relying on the SUS304 stainless construction to resist mild chemical corrosion.
Is the Airtac PB Pen-type Cylinder PB12X225SU the Right Cylinder?
Selecting this 12 mm bore unit means sizing for a 56.5 N push at 0.5 MPa, which sits between the smaller Ø10 (39.3 N) and the larger Ø16 (100.5 N). Keep in mind the thin Ø5 mm rod is designed for coaxial thrust; over this extended 225 mm stroke, adding an external guide or linear bearing is highly recommended to prevent side-load damage.
When ordering, confirm the essentials: 12 mm bore, 225 mm non-standard stroke, M5x0.8 port, the built-in S magnet for AirTAC reed or electronic switches, and the U-type 90-degree side inlet. Note that a plain PB cylinder does not hold its load if air pressure is lost or the valve is centered, as the piston will drift and the bumper only decelerates near the stroke end. An external rod lock is required for fail-safe holding.
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 PB12X225SU FAQ
This double-acting cylinder generates 56.5 N of push and 46.7 N of pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it produces 79.1 N of push and 65.4 N of pull. It operates between 0.15 and 0.7 MPa, with a speed range of 50-800 mm/s.
The 225 mm stroke exceeds the 200 mm standard maximum for a 12 mm bore, making it a non-standard, made-to-order part. 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, so for high-speed or heavy tooling mass, you should meter-out the exhaust or add an external shock absorber.
