Airtac PB Pen-type Cylinder PB12X75SCB
The AirTAC Airtac PB Pen-type Cylinder PB12X75SCB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 75mm 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 PB12X75SCB
The AirTAC PB12X75SCB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It features a slim SUS304 stainless barrel and piston rod that shrugs off damp or mildly corrosive environments, making it ideal for tight jigs and light end-of-arm tooling where space and payload are critical. Delivering 56.5 N of push force at 0.5 MPa, it uses an M5x0.8 air port and a 5 mm rod with an M10x1.0 end thread for secure load coupling.
This 75 mm stroke variant includes a built-in piston magnet (S) for position sensing via AirTAC reed or electronic switches. The CB double clevis back cover accommodates pivoting loads. Because the fixed TPU bumper at each end only decelerates the last few millimeters of travel, high-speed cycles with real tooling mass 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 PB12X75SCB Is Used
PCB Depaneling Router
Actuates a cutting head or clamping fixture on a depaneling machine, where the slim 12 mm body fits between closely spaced routing tracks and the CB clevis handles minor pivot alignment.
Blister Pack Sealing
Closes a small heated platen on a pharmaceutical blister line, using the 56.5 N thrust to press card and foil together while the stainless build resists humid processing areas.
Sorting Diverter Gate
Pushes lightweight plastic bottles or cartons laterally on a narrow conveyor belt, relying on the 75 mm stroke and built-in magnet to confirm gate extension at high cycle rates.
Is the Airtac PB Pen-type Cylinder PB12X75SCB the Right Cylinder?
When sizing this 12 mm bore actuator, consider stepping down to the 10 mm bore if your load is lighter, which provides 39.3 N of push at 0.5 MPa. If you need more thrust, the 16 mm bore offers 100.5 N at the same pressure. For the PB12X75SCB, plan for a safe working load of roughly 34 N (about 60 percent of the 56.5 N theoretical force) to account for seal friction and smooth travel. This equates to lifting approximately 2.9 kg vertically with a sane 2:1 safety margin.
A plain pneumatic body does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the bumper only decelerates near the stroke end. For fail-safe holding, specify an external rod lock. Confirm your ordering essentials: 12 mm bore, 75 mm stroke, M5x0.8 port, S magnet, CB double clevis, and any LB, FA, or CJ mounting brackets.
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 PB12X75SCB FAQ
This double-acting single-rod cylinder generates 56.5 N push and 46.7 N pull at 0.5 MPa. 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 and 0.7 MPa, runs at speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
No, a standard PB body drifts when air is removed or the valve is centered, as the fixed TPU bumper only decelerates the piston near the stroke end rather than locking it. To maintain a vertical position safely, you must install an external rod lock or mechanical stop.
