Airtac PB Pen-type Cylinder PB12X175CB
The AirTAC Airtac PB Pen-type Cylinder PB12X175CB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 175mm 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 PB12X175CB
The AirTAC PB12X175CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a SUS304 stainless steel piston rod and slim round barrel to resist damp or mildly corrosive production areas while saving payload on end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, this unit pairs a 12 mm bore with a 175 mm stroke.
Air connects via an M5x0.8 port, and the rod-end utilizes an M10x1.0 thread for secure load coupling. Because this variant uses the CB double clevis back cover, it accommodates pivoting loads. The Ø6-Ø16 bore range employs a fixed TPU bumper at each end to decelerate travel, though it is not field-adjustable.

| 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 PB12X175CB Is Used
Pivot-Actuated Clamp
Swings a small latch on a machining fixture using the CB double clevis, applying up to 56.5 N of clamping pressure at 0.5 MPa.
Diverter Arm Mechanism
Pushes lightweight plastic bottles on a packaging line, where the SUS304 barrel withstands washdown and the 175 mm stroke reaches across the belt.
PCB Test Head
Drives an electronic probe array downward onto circuit boards, relying on the pen-size profile to fit between dense testing lanes.
Is the Airtac PB Pen-type Cylinder PB12X175CB the Right Cylinder?
When sizing this actuator, stepping down to the Ø10 bore yields 39.3 N push at 0.5 MPa, while stepping up to the Ø16 bore provides 100.5 N, allowing you to scale thrust precisely. The thin Ø5 mm piston rod is designed strictly for coaxial thrust; over this 175 mm stroke, any off-axis loading demands an external guide or linear bearing to prevent binding. Confirm your ordering essentials: 12 mm bore, 175 mm stroke, M5x0.8 port, CB double clevis, and no sensor magnet.
A standard PB body does not hold its position if air pressure drops or the valve is centered, as the piston will drift and the bumper only decelerates near the stroke end. If your application requires a fail-safe hold under load, an external stop or rod lock must be fitted.
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 PB12X175CB 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 force is 79.1 N and the pull force is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
The CB back cover provides a double clevis joint ideal for pivoting linkages. To manage impact, a fixed TPU bumper at each end decelerates the piston over the final few millimeters. Because it is not adjustable, high-speed cycles with real tooling mass may require metering out the exhaust or adding an external shock absorber.
