Airtac PB Pen-type Cylinder PB12X75SULB
The AirTAC Airtac PB Pen-type Cylinder PB12X75SULB is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 75mm 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 PB12X75SULB
The AirTAC PB12X75SULB is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It delivers a theoretical push of 56.5 N and pull of 46.7 N at 0.5 MPa, driven through an M5x0.8 port. The slim SUS304 stainless round barrel and screwed-in covers provide excellent durability in damp or mildly corrosive work areas while keeping mass low for end-of-arm tooling.
This specific configuration includes a built-in piston magnet (S) for position sensing, a U-style 90-degree perpendicular side air inlet for flat plumbing, and an LB mounting bracket. It uses a fixed TPU bumper at each end to decelerate the stroke. Because the 5 mm rod is designed for coaxial thrust, external guiding is recommended if side loads are present.

| 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 PB12X75SULB Is Used
PCB Depaneling Router
Actuates a tooling pin on an automated router fixture, utilizing the 34 N safe working load to hold small daughterboards firmly during the cutting routing process.
Blister Pack Sealing
Cycles a small heat platen in a packaging line, where the slim stainless body resists humidity and the 90-degree U inlet keeps plumbing flush against the machine frame.
Light Pick-and-Place
Drives a tiny vacuum gripper on a Cartesian handler, lifting electronic components weighing up to 2.9 kg vertically with a safe 2:1 margin at 0.5 MPa.
Is the Airtac PB Pen-type Cylinder PB12X75SULB the Right Cylinder?
When sizing this 12 mm bore actuator, consider stepping down to the 10 mm bore if your load requires less force (it provides 39.3 N push at 0.5 MPa), or moving up to the 16 mm bore for heavier tasks (100.5 N push at 0.5 MPa). For the PB12X75SULB, plan for a safe working load of about 34 N, which is roughly 60 percent of the 56.5 N theoretical output, ensuring smooth travel against seal friction.
Keep in mind that a standard double-acting cylinder drifts when air pressure is lost or the valve is centered, as the bumper only decelerates near the stroke end rather than locking the rod. To verify your build, confirm the 12 mm bore, 75 mm stroke, M5x0.8 porting, the S magnet for reed or electronic switches, the U side inlet, and the LB 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 PB12X75SULB FAQ
At 0.5 MPa this cylinder pushes with 56.5 N and pulls with 46.7 N. At the maximum operating pressure of 0.7 MPa, the push is 79.1 N and the pull is 65.4 N. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
It features fixed TPU bumpers at both ends that decelerate the piston over the last few millimeters; for high mass or speed, add an external shock absorber. The built-in S magnet allows position detection using either AirTAC reed or electronic solid-state switches.
