Airtac PB Pen-type Cylinder PB12X60SU
The AirTAC Airtac PB Pen-type Cylinder PB12X60SU 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 PB12X60SU
The AirTAC PB12X60SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 12mm bore and a 60mm stroke, generating 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. The slim SUS304 stainless barrel and piston rod provide durability in damp or mildly corrosive environments, while keeping weight low for end-of-arm tooling. A built-in piston magnet (-S) allows position detection.
This variant uses a U-type back cover, meaning the M5x0.8 air port enters from the side at a 90-degree angle for flat plumbing in space-constrained jigs. Travel speed reaches 50-800 mm/s, with a fixed TPU bumper at each end to decelerate the piston near the stroke limits. The Ø5 mm piston rod has an M10x1.0 rod-end thread for secure load coupling.

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 PB12X60SU Is Used
PCB Depaneling Jig
Drives a low-friction cutting blade or separator pin in a tight electronics assembly fixture, using the 56.5 N extend force to snap boards apart cleanly.
Carton Flap Folder
Tucks small corrugated box flaps on a packaging line, where the U side inlet keeps plumbing flush against the machine frame to save space.
Lab Sample Dispenser
Actuates a small pipette or valve block in wet laboratory automation, benefiting from the SUS304 stainless build to resist mild chemical moisture.
Is the Airtac PB Pen-type Cylinder PB12X60SU the Right Cylinder?
If you need less force, stepping down to the Ø10 bore yields 39.3 N push at 0.5 MPa; if you need more, stepping up to the Ø16 bore provides 100.5 N push at 0.5 MPa. Confirm your ordering essentials: 12mm bore, 60mm stroke, M5x0.8 port, S magnet, and U side inlet.
Because the thin Ø5 mm rod is designed strictly for coaxial thrust, avoid side loading and add an external linear guide if the load is off-axis. Note that a plain PB-type cylinder does not hold its position if air pressure is lost or the valve is centred—the piston will drift. For fail-safe load holding, an external rod lock or mechanical stop is required.
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 PB12X60SU 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 proof pressure of 1.2 MPa and a speed range of 50-800 mm/s.
This cylinder uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters of travel; it is not field-adjustable, so for high-speed or heavy tooling mass you should meter-out the exhaust or add an external shock absorber. The built-in -S magnet allows you to track position using AirTAC reed or electronic switches.
