Airtac PB Pen-type Cylinder PB12X65SU
The AirTAC Airtac PB Pen-type Cylinder PB12X65SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 65mm 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 PB12X65SU
The AirTAC PB12X65SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a 12mm bore and a 65mm stroke, generating 56.5 N of push force and 46.7 N of pull force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide durability in damp or mildly corrosive environments while keeping end-of-arm tooling weight to an absolute minimum.
This specific configuration includes a built-in piston magnet (-S) for compatibility with AirTAC reed or electronic switches, and a U-type back cover offering a 90-degree side air inlet for flat plumbing in tight spaces. Air connections use an M5x0.8 port, and the rod-end features an M10x1.0 thread for secure load coupling. A fixed TPU bumper at each end absorbs end-of-stroke impact, and the Ø5 mm rod is designed strictly for coaxial thrust.

| Stroke | 65 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 PB12X65SU Is Used
PCB Depaneling Jig
Actuates a routing blade or clamp in a tight electronics assembly cell, using the 90-degree side inlet to keep pneumatic plumbing flush against the machine frame.
Blister Pack Tucking
Drives a small folding flap to seal pharmaceutical blister packs, where the SUS304 body withstands wipe-down cleaning and the 56.5 N push easily creases card stock.
Lab Dispenser Positioning
Moves a pipette head over a micro-titre plate, benefiting from the pen-size footprint to fit multi-channel heads without adding payload mass to the gantry.
Is the Airtac PB Pen-type Cylinder PB12X65SU the Right Cylinder?
When sizing this actuator, stepping down to a Ø10 bore yields 39.3 N of push force at 0.5 MPa, while stepping up to a Ø16 bore provides 100.5 N. Because the Ø5 mm rod is slender, add an external guide or linear bearing for off-axis loads over this 65mm stroke. Note that a plain PB cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, requiring an external stop or rod lock for fail-safe holding. Confirm your ordering essentials: 12mm bore, 65mm stroke, M5x0.8 port, S magnet, U side inlet, and no mounting bracket.
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 PB12X65SU 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 of 50-800 mm/s.
This model uses a fixed TPU bumper at each end that decelerates the piston over the last few millimeters; it is not adjustable, so for high-speed or heavy tooling mass you should meter-out the exhaust or add an external shock absorber. The -S option includes a piston magnet for AirTAC reed or electronic switches, allowing precise position detection.
