Airtac PB Pen-type Cylinder PB12X200CB
The AirTAC Airtac PB Pen-type Cylinder PB12X200CB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 200mm 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 PB12X200CB
The AirTAC PB12X200CB 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. Delivering 56.5 N of push force at 0.5 MPa, this model is built for precise thrust.
This specific configuration includes a CB double clevis back cover, allowing the body to pivot smoothly on a pin to accommodate lateral movement during the stroke. Air connects via an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling. The Ø6-Ø16 bore range utilizes a fixed TPU bumper at each end to decelerate the piston near the stroke limits, and this unit reaches the maximum standard stroke of 200 mm for its size.

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 PB12X200CB Is Used
PCB Depaneling Router
Pivots a routing tool head along a 200 mm path to singulate printed circuit boards, utilizing the CB clevis to maintain tool alignment during lateral chassis shifts.
Package Divert Arm
Extends a sweeping gate to sort small lightweight parcels on a conveyor line, relying on the fixed TPU bumpers to absorb the impact at the end of the 200 mm travel.
Lab Sample Dispenser
Drives a pipette array across a multi-well tray in wet laboratory environments, benefiting from the SUS304 stainless construction to resist mild chemical corrosion.
Is the Airtac PB Pen-type Cylinder PB12X200CB the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø10 bore if your payload is lighter, which provides 39.3 N of push at 0.5 MPa. If you need more authority, stepping up to the Ø16 bore yields 100.5 N at the same pressure.
Because this unit features a 200 mm stroke, the slender Ø5 mm piston rod is highly susceptible to side-loading and buckling; always use an external linear bearing or guide to maintain coaxial thrust. A plain double-acting cylinder will drift and cannot hold a load if air pressure is lost or the valve is centered, so install an external rod lock or mechanical stop for fail-safe positioning. Confirm your ordering essentials: 12 mm bore, 200 mm stroke, M5x0.8 port, CB double clevis back cover, and no sensor magnet.
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 PB12X200CB 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 proof pressure of 1.2 MPa, and the operational speed range is 50-800 mm/s.
No, a standard double-acting pen cylinder will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston near the end of the stroke and does not act as a locking brake. For vertical or gravity-loaded applications, you must add an external rod lock or mechanical stop to hold the position safely.
