Airtac PB Pen-type Cylinder PB12X30R
The AirTAC Airtac PB Pen-type Cylinder PB12X30R is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 30mm 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 PB12X30R
The AirTAC PB12X30R is a double-acting JIS pen-size mini cylinder engineered for compact, 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. Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore unit is both small and fast, operating at speeds between 50-800 mm/s.
This specific configuration includes an R axial air inlet for in-line plumbing and an M5x0.8 port. It relies on a fixed TPU bumper at each end to decelerate the stroke, rather than an adjustable air cushion. Because the bumper only absorbs energy over the final few millimeters, high-speed cycles with heavy tooling require metering out the exhaust or adding an external shock absorber.

| 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 |

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 PB12X30R Is Used
Carton Flap Folder
Tucks small corrugated box flaps on a packaging line, utilizing the compact stainless body to fit within narrow conveyor side rails.
Pick-and-Place Ejector
Pushes lightweight plastic components out of a mold cavity on an end-of-arm tooling plate, benefiting from the 50-800 mm/s speed range.
Is the Airtac PB Pen-type Cylinder PB12X30R the Right Cylinder?
When sizing this actuator, the PB12X30R provides a theoretical push of 56.5 N and a pull of 46.7 N at 0.5 MPa. If you need less force, stepping down to the 10 mm bore yields 39.3 N of push, while moving up to the 16 mm bore provides 100.5 N at the same pressure. Keep in mind a plain PB cylinder drifts when air is lost or the valve is centered, so applications requiring fail-safe holding need an external rod lock. Confirm your ordering essentials: 12 mm bore, 30 mm stroke, M5x0.8 port, R axial inlet, and no sensor magnet.
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 PB12X30R FAQ
This 12 mm bore double-acting cylinder has an M5x0.8 port and generates 56.5 N push / 46.7 N pull at 0.5 MPa, and 79.1 N push / 65.4 N pull at the maximum 0.7 MPa operating pressure.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the stroke end and does not act as a brake. An external stop or rod lock is required for fail-safe load holding.
