Airtac PB Pen-type Cylinder PB12X35SU
The AirTAC Airtac PB Pen-type Cylinder PB12X35SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 35mm 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 PB12X35SU
The AirTAC PB12X35SU is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency actuation. It features a slim SUS304 stainless steel barrel and piston rod, offering robust resistance in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, it operates at speeds from 50-800 mm/s.
This variant includes a built-in piston magnet for position sensing and a U-type back cover providing a 90-degree side air inlet for flat plumbing. The M5x0.8 port and M10x1.0 rod-end thread simplify integration. It relies on a fixed TPU bumper at each end for end-of-stroke deceleration, which is not field-adjustable.

| Rod diameter | Ø5 mm |
| Stroke | 35 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 |
| Cushion | Elastic bumper (both ends) |

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 PB12X35SU Is Used
PCB Depaneling Jig
Actuates a routing blade fixture in tight electronics assembly cells, utilizing the 35mm stroke and slim stainless body to fit within dense conveyor machinery.
Blister Pack Sealing
Provides consistent downward clamping force for thin film sealing heads, where the 90-degree side inlet keeps plumbing flush against the machine frame.
Lab Dispenser Valve
Drives a micro-dosing piston for reagent distribution, benefiting from the magnetic sensor feedback to confirm exact volumetric shot closure.
Is the Airtac PB Pen-type Cylinder PB12X35SU the Right Cylinder?
When sizing this 12mm bore actuator, consider stepping down to the Ø10 model for lighter duties (39.3 N push at 0.5 MPa) or up to the Ø16 for heavier loads (100.5 N push at 0.5 MPa).
Confirm your ordering essentials: 12mm bore, 35mm stroke, M5x0.8 port, S magnet for reed or electronic switches, and the U 90-degree side inlet. Note that a plain PB cylinder drifts if air pressure is lost or the valve is centered, so an external rod lock is required for fail-safe load holding. Additionally, the Ø5 mm rod is built for coaxial thrust, so use an external guide if handling off-axis loads.
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 PB12X35SU 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.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters, which is not adjustable, so you may need an external shock absorber for high-mass loads. The built-in S magnet allows position detection using either AirTAC reed or electronic solid-state switches.
