Airtac PB Pen-type Cylinder PB12X65SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X65SCB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 65mm 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 PB12X65SCB
The AirTAC PB12X65SCB is a JIS pen-size double-acting mini cylinder engineered for compact, high-frequency small-part motion. It features a SUS304 stainless steel piston rod and slim round barrel, providing excellent durability in damp or mildly corrosive work areas. Delivering 56.5 N of push force at 0.5 MPa, this 12 mm bore unit uses an M5x0.8 air port and an M10x1.0 rod-end thread for secure load coupling.
Because this configuration includes the S option, it carries a built-in piston magnet ready for AirTAC reed or electronic switches to track position. The CB double clevis back cover supports pivoting loads, while fixed TPU bumpers at each end absorb end-of-stroke impact.

| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 65 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) |

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 PB12X65SCB Is Used
PCB Depaneling Jig
Actuates a routing blade or clamping arm in tight electronics assembly cells where the slim 12 mm barrel saves valuable tooling space.
Pouch Sealing Flap
Drives a lightweight sealing bar at 50-800 mm/s to close small retail packaging, using the CB clevis to accommodate pivot geometry.
Lab Sample Sorter
Pushes vial racks along a guide with a 56.5 N extend force, relying on the SUS304 construction to resist humid laboratory environments.
Is the Airtac PB Pen-type Cylinder PB12X65SCB the Right Cylinder?
When sizing this 12 mm bore actuator, stepping down to a 10 mm bore yields 39.3 N of push at 0.5 MPa, whereas stepping up to a 16 mm bore provides 100.5 N, letting you tune the force to your exact jig requirements. To verify your ordering essentials for the PB12X65SCB: confirm the 12 mm bore, 65 mm stroke, M5x0.8 port, the S magnet for sensing, and the CB double clevis mount. Note that a plain double-acting cylinder drifts when air is lost or the valve is centered; the bumper only decelerates near stroke end, so add an external rod lock if your process must hold a load without live pressure.
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 PB12X65SCB FAQ
At 0.5 MPa this 12 mm bore cylinder provides 56.5 N push and 46.7 N pull. At the maximum operating pressure of 0.7 MPa, it yields 79.1 N push and 65.4 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
The CB suffix denotes a double clevis back cover designed for pivoting loads. Deceleration relies on fixed TPU bumpers at each end, which are not adjustable. If moving real tooling mass at high speed, meter-out the exhaust or add an external shock absorber, as the bumper only decelerates the last few millimeters.
