Airtac PB Pen-type Cylinder PB12X110SU
The AirTAC Airtac PB Pen-type Cylinder PB12X110SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 110mm 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 PB12X110SU
The AirTAC PB12X110SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 12mm bore and a 110mm 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 corrosion resistance for damp production zones, while the M5x0.8 port keeps pneumatic plumbing compact.
This variant includes a built-in piston magnet (-S) for position sensing with AirTAC reed or electronic switches, plus a U-type back cover offering a 90-degree side air inlet for flat routing. Because the 110mm stroke is relatively long for the Ø5 mm rod, maintaining coaxial alignment is critical to prevent side-loading wear. The ends rely on fixed TPU bumpers rather than adjustable cushions, meaning heavy tooling mass at high speeds may require external shock absorption.

| Stroke | 110 mm |
| Acting type | Double acting |
| Port size | M5×0.8 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 0.7 MPa |
| Proof pressure | 1.2 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 50 – 800 mm/s |

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 PB12X110SU Is Used
PCB Depaneling Router
Advances a tooling head across 110mm to singulate printed circuit boards, utilizing the 56.5 N push force to maintain steady feed without stressing the delicate substrate.
Carton Flap Folder
Tucks minor flaps on small packaging lines; the U-type side inlet keeps the pneumatic hoses flush against the machine frame to avoid snagging on passing boxes.
Pick-and-Place Ejector
Pushes lightweight electronic components out of a nested tray, relying on the -S magnet and an electronic switch to confirm the 110mm ejection stroke is fully complete.
Is the Airtac PB Pen-type Cylinder PB12X110SU the Right Cylinder?
If you need less force, stepping down to the Ø10 bore provides 39.3 N of push at 0.5 MPa; stepping up to the Ø16 bore yields 100.5 N. Note that a standard PB body does not hold its position if air pressure drops or the valve is centered—the piston will drift, so an external rod lock is required for fail-safe holding.
To order, confirm the 12mm bore, 110mm stroke, M5x0.8 port, built-in magnet (S), and U-type 90-degree side inlet. You can mount it using standard AirTAC LB, FA, or CJ brackets.
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 PB12X110SU 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 speed range of 50-800 mm/s.
It uses fixed TPU bumpers at both ends, which only decelerate the piston over the last few millimeters. It is not an adjustable air cushion or a locking brake. If you are moving real tooling mass at high speed, you should meter-out the exhaust or add an external shock absorber to prevent bottoming out.
