Airtac PB Pen-type Cylinder PB12X35SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X35SCB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 35mm 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 PB12X35SCB
The AirTAC PB12X35SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It provides a theoretical push of 56.5 N and pull of 46.7 N at 0.5 MPa, driven through an M5x0.8 air port. The slim SUS304 stainless barrel and piston rod resist damp or mildly corrosive environments while keeping weight low for end-of-arm tooling.
Equipped with a built-in piston magnet (S code), this unit supports AirTAC reed or electronic switches for position detection. The CB double clevis back cover accommodates pivoting loads, while fixed TPU bumpers at both ends absorb end-of-stroke impact.

| Rod diameter | Ø5 mm |
| Stroke | 35 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 |

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 PB12X35SCB Is Used
PCB Depaneling Router
Actuates a cutting head pivot on an automated router, utilizing the CB clevis to swing the blade assembly smoothly into position.
Pouch Sealing Clamp
Cycles a small hold-down jaw on a vertical form-fill machine, where the compact stainless body withstands washdown environments.
Connector Sorting Gate
Diverts electronic parts on a vibratory bowl feeder using the S magnet and a solid-state switch to verify the 35mm stroke position.
Is the Airtac PB Pen-type Cylinder PB12X35SCB the Right Cylinder?
When sizing this 12mm bore actuator, stepping down to the 10mm bore yields 39.3 N of push at 0.5 MPa, whereas stepping up to the 16mm bore provides 100.5 N. The Ø5 mm piston rod features an M10x1.0 end thread for secure load coupling, but over its 35 mm stroke you should maintain coaxial alignment to avoid side loading. If your pivot mechanism requires fail-safe holding, note that a standard PB cylinder drifts when air pressure is lost; an external rod lock is necessary to secure the load.
Confirm your ordering essentials: 12mm bore, 35mm stroke, M5x0.8 port, S magnet for sensing, and CB double clevis mount. Operating pressure spans 0.15-0.7 MPa with speeds from 50-800 mm/s.
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 PB12X35SCB FAQ
At 0.5 MPa this cylinder generates 56.5 N of push and 46.7 N of pull. At the maximum operating pressure of 0.7 MPa, push increases to 79.1 N and pull to 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the end of its stroke and does not act as a brake. For vertical or suspended loads, you must install an external rod lock or mechanical stop.
