Airtac PB Pen-type Cylinder PB12X30SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X30SCB 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 PB12X30SCB
The AirTAC PB12X30SCB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It delivers 56.5 N of push and 46.7 N of pull at 0.5 MPa, driven through an M5x0.8 air port. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive work areas while keeping end-of-arm tooling extremely light.
This specific configuration includes a built-in piston magnet for position sensing with AirTAC reed or electronic switches, plus a CB double clevis back cover for pivoting loads. End-of-stroke energy is managed by a fixed TPU bumper at each end. Because the bumper only decelerates the final few millimeters, high-speed tooling mass may 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 |

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 PB12X30SCB Is Used
Pouch Sealing Clamp
Pivots a sealing jaw via the CB double clevis to crimp open-ended food packaging, fitting neatly within tight machine guarding.
Lab Sample Ejector
Pushes tested vials out of a centrifuge carousel using the 56.5 N extend force, with the -S magnet confirming ejection to the control system.
Is the Airtac PB Pen-type Cylinder PB12X30SCB the Right Cylinder?
If your task needs less force, stepping down to the 10mm bore provides 39.3 N push at 0.5 MPa. For heavier demands, the 16mm bore offers 100.5 N push at 0.5 MPa. A plain PB cylinder does not hold its load if air pressure drops or the valve is centered, so an external rod lock is required for fail-safe positioning.
Confirm your ordering essentials to match this exact unit: 12mm bore, 30mm stroke, M5x0.8 port, built-in magnet (S), and CB double clevis mount. The Ø5 mm piston rod features an M10x1.0 rod-end thread for secure load coupling. Since the rod is designed for coaxial thrust, avoid side loading and add an external linear bearing if guiding off-axis loads.
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 PB12X30SCB FAQ
At 0.5 MPa this cylinder pushes with 56.5 N and pulls with 46.7 N. At the maximum operating pressure of 0.7 MPa, push increases to 79.1 N and pull to 65.4 N. It operates on filtered air between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, the piston will drift if air pressure is lost or the valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke ends; they do not act as a locking brake. An external stop or rod lock is necessary for fail-safe load holding.
