Airtac PB Pen-type Cylinder PB12X5SU
The AirTAC Airtac PB Pen-type Cylinder PB12X5SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 5mm 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 PB12X5SU
The AirTAC PB12X5SU is a double-acting JIS pen-size mini cylinder engineered for high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling exceptionally light. With a 12 mm bore and 5 mm stroke, it generates 56.5 N of push force at 0.5 MPa.
This configuration includes a built-in piston magnet for AirTAC reed or electronic switches, plus a U-type 90-degree side air inlet for flat plumbing. The M5x0.8 port and M10x1.0 rod-end thread simplify integration. It relies on a fixed TPU bumper at each end to decelerate the last few millimeters of travel rather than an adjustable air cushion.
Airtac PB Pen-type Cylinder PB12X5SU Technical Specifications
| Model | Airtac PB Pen-type Cylinder PB12X5SU |
|---|---|
| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 5 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 PB12X5SU Is Used
Pick-and-Place Ejector
Short 5 mm stroke to eject small electronic components from a test socket with precise 56.5 N push at 0.5 MPa.
Pouch Sealing Clamp
Rapid high-frequency clamping of thin film packaging materials, utilizing the U side inlet for flat manifold mounting in tight spaces.
Sensor Actuation
Triggering micro-limit switches on a conveyor line where the SUS304 body withstands washdown environments.
Is the Airtac PB Pen-type Cylinder PB12X5SU the Right Cylinder?
If you need to step down, the Ø10 bore provides 39.3 N push at 0.5 MPa, while stepping up to the Ø16 bore yields 100.5 N. Keep the thin Ø5 mm rod coaxial to avoid side load, as it is designed strictly for thrust.
A plain PB cylinder drifts when air is lost or the valve is centered, as the bumper only decelerates near stroke end rather than locking the load; use an external rod lock for fail-safe holding. When ordering, confirm the 12 mm bore, 5 mm stroke, M5x0.8 port, S magnet, and U side 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 PB12X5SU 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.
No, the piston will drift if air is lost. The fixed TPU bumper only decelerates the piston near the stroke end; it does not act as a lock. An external stop or rod lock is required for fail-safe load holding.
