Airtac PB Pen-type Cylinder PB12X200U
The AirTAC Airtac PB Pen-type Cylinder PB12X200U 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 PB12X200U
The AirTAC PB12X200U is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers 56.5 N of push and 46.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel round barrel and a 5 mm rod. The U option provides a 90-degree side air inlet, enabling flat plumbing in confined spaces. Air connections use an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling.
This model relies on a fixed TPU bumper at each end to decelerate the piston over its 200 mm travel, as it lacks an adjustable air cushion. Because the rod is only 5 mm thick, it is built for coaxial thrust rather than side loading; over this extended stroke, adding an external guide or linear bearing prevents deflection. The bumper only absorbs impact near the stroke ends, so metering out the exhaust or adding an external shock absorber is advised when moving heavier tooling masses at higher speeds.

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 PB12X200U Is Used
PCB Depaneling Router
Pushes a light carrier fixture along a linear rail to position uncut circuit boards under a high-speed routing spindle.
Blister Pack Loader
Advances a thin plastic film feed over 200 mm to register cavities beneath a sealing head in medical packaging lines.
Lab Sample Dispenser
Actuates a small pipette array downward to dispense reagents into test tube racks without occupying valuable bench space.
Is the Airtac PB Pen-type Cylinder PB12X200U 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, while stepping up to a 16 mm bore provides 100.5 N. A plain PB body does not hold its position if air pressure drops or the valve is centered, as the piston will drift; incorporate an external rod lock for fail-safe holding. Confirm your ordering essentials: 12 mm bore, 200 mm stroke, M5x0.8 port, U side inlet, 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 PB12X200U FAQ
At 0.5 MPa, this 12 mm bore double-acting cylinder provides 56.5 N of push and 46.7 N of 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 with speeds of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumpers only decelerate the piston near the stroke ends and do not function as a locking brake. An external stop or rod lock is required for fail-safe load holding.
