Airtac PB Pen-type Cylinder PB12X60CB
The AirTAC Airtac PB Pen-type Cylinder PB12X60CB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 60mm 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 PB12X60CB
The AirTAC PB12X60CB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while saving valuable space and payload on light end-of-arm tooling. Generating 56.5 N of push force and 46.7 N of pull force at 0.5 MPa, it is equipped with an M5x0.8 air port and an M10x1.0 rod-end thread for secure load coupling.
This 12mm bore, 60mm stroke variant includes a CB double clevis back cover, allowing the body to pivot smoothly on a pin mount. Because the unit uses a fixed TPU bumper at each end rather than an adjustable air cushion, it is best suited for applications where metering the exhaust or adding an external shock absorber can manage higher kinetic energy. The thin Ø5 mm piston rod is designed strictly for coaxial thrust, so external linear bearings should be added if side loads are present.

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 PB12X60CB Is Used
PCB Depaneling Jig
Actuates a small cutting blade or clamping arm in tight electronics assembly cells where the slim 12mm barrel prevents collision with adjacent fixtures.
Pouch Flap Folding
Pivots via the CB clevis to tuck packaging flaps on a vertical form-fill-seal machine, utilizing the 56.5 N push force to crease light cardboard cleanly.
Lab Sample Sorter
Indexes small vials along a conveyor guide in a diagnostic instrument, benefiting from the SUS304 build resisting humid laboratory environments.
Is the Airtac PB Pen-type Cylinder PB12X60CB the Right Cylinder?
When sizing this model, consider stepping down to the Ø10 bore (39.3 N push at 0.5 MPa) for lighter tooling, or up to the Ø16 bore (100.5 N push at 0.5 MPa) if you need substantially more thrust.
Note that a standard double-acting cylinder 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 rather than locking the load. For fail-safe holding, an external rod lock or mechanical stop is required. To order, confirm the 12mm bore, 60mm stroke, M5x0.8 port, CB double clevis back cover, and whether you need an LB, FA, or CJ mounting bracket.
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 PB12X60CB FAQ
At 0.5 MPa, the push (extend) force is 56.5 N and the pull (retract) 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 and a proof pressure of 1.2 MPa.
The CB back cover is a double clevis that allows the cylinder body to pivot, which is ideal for articulating mechanisms. For impact absorption, the cylinder uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters. It is not an adjustable air cushion, so for high-speed or heavy tooling mass, you should meter-out the exhaust or install an external shock absorber.
