Airtac PB Pen-type Cylinder PB12X160U
The AirTAC Airtac PB Pen-type Cylinder PB12X160U is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 160mm 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 PB12X160U
The AirTAC PB12X160U is a JIS pen-size double-acting single-rod mini cylinder engineered for compact automation. It delivers 56.5 N of push and 46.7 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a 5 mm rod. The integrated U option provides a 90-degree side air inlet, keeping your plumbing flat against the machine frame, while the M5x0.8 port and M10x1.0 rod-end thread ensure straightforward load coupling.
Because this 160 mm stroke approaches the 200 mm standard limit for a 12 mm bore, the slender 5 mm rod requires strict coaxial alignment. End-of-travel deceleration relies on fixed TPU bumpers rather than adjustable air cushions, meaning high-speed tooling mass might require external shock absorption.

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 PB12X160U Is Used
PCB Depaneling Router
Pushes a light carrier fixture along a linear guide to position circuit boards under a cutting spindle, utilizing the 90-degree side inlet to save vertical clearance.
Blister Pack Sorting
Extends 160 mm to deflect pharmaceutical blister packs into a reject chute, relying on the 56.5 N extend force to overcome light packaging friction.
Lab Sample Dispenser
Actuates a small dosing valve for liquid reagents where the SUS304 barrel resists ambient humidity and the compact pen-size body fits inside a crowded fume hood.
Is the Airtac PB Pen-type Cylinder PB12X160U the Right Cylinder?
When sizing this actuator, stepping down to the 10 mm bore yields 39.3 N push at 0.5 MPa, while stepping up to the 16 mm bore provides 100.5 N, letting you fine-tune payload capacity. To verify your setup, confirm the 12 mm bore, 160 mm stroke, M5x0.8 port, U side inlet, and absence of a sensor magnet. If your process must maintain vertical position during a pressure loss, note that this cylinder will drift; an external rod lock or mechanical stop is required for fail-safe holding.
The fixed TPU bumper only decelerates the piston over the final few millimeters of travel and is not a braking mechanism.
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 PB12X160U FAQ
At 0.5 MPa, this double-acting cylinder provides 56.5 N of push (extend) and 46.7 N of pull (retract). At the maximum operating pressure of 0.7 MPa, the push is 79.1 N and the pull is 65.4 N. The operating pressure range is 0.15-0.7 MPa, with a speed range of 50-800 mm/s.
The U designation means the air inlet enters at a 90-degree angle to the cylinder axis, allowing flat plumbing along a machine frame. At stroke ends, energy is absorbed by fixed TPU bumpers rather than adjustable air cushions, so for high-speed or heavy tooling, you should meter-out the exhaust or add an external shock absorber.
