Airtac PB Pen-type Cylinder PB12X5SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X5SCB 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 PB12X5SCB
The AirTAC PB12X5SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for high-frequency small-part motion. It features a 12mm bore and a 5mm stroke, generating 56.5 N of push and 46.7 N of pull at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Air connects via an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling.
This variant includes a built-in piston magnet (S) for position sensing with AirTAC reed or electronic switches, plus a CB double clevis back cover for pivoting loads. Deceleration is handled by a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only absorbs impact over the final few millimeters, metering out the exhaust or adding an external shock absorber is recommended when cycling real tooling mass at higher speeds.

| 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 |

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 PB12X5SCB Is Used
Pick-and-Place Ejection
Short 5mm ejection stroke on a PCB assembly line, using the CB clevis to pivot slightly and the S magnet to confirm retraction before the conveyor advances.
Film Clamping
Actuating a small flow-wrap jaw to seal packaging film, where the fixed TPU bumper quietly stops the 12mm piston at cycle rates approaching 800 mm/s.
Sensor Positioning
Indexing a vision system camera mount a few millimeters into focus, taking advantage of the SUS304 build to resist washdown moisture in a food processing area.
Is the Airtac PB Pen-type Cylinder PB12X5SCB the Right Cylinder?
Selecting this 12mm bore model gives 56.5 N push at 0.5 MPa. If you need less force, the 10mm bore provides 39.3 N; stepping up to the 16mm bore yields 100.5 N. Keep the thin Ø5 mm rod coaxial to avoid side loading, adding a linear bearing if guiding off-axis loads. A plain PB cylinder drifts when air is lost or the valve is centered, so install an external rod lock if the application requires fail-safe position holding. Confirm ordering essentials: 12mm bore, 5mm stroke, M5x0.8 port, S magnet, and CB double clevis.
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 PB12X5SCB 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 is 79.1 N and the pull is 65.4 N. The cylinder operates between 0.15-0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
The CB suffix denotes a double clevis back cover, allowing the cylinder to pivot smoothly on a pin to accommodate load misalignment. The S suffix means the piston contains a magnet for non-contact position sensing, compatible with AirTAC reed or electronic switches mounted along the SUS304 barrel.
