Airtac PB Pen-type Cylinder PB12X10SU
The AirTAC Airtac PB Pen-type Cylinder PB12X10SU is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 10mm 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 PB12X10SU
The AirTAC PB12X10SU is a double-acting JIS pen-size mini cylinder engineered for short-stroke, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, offering excellent durability in damp or mildly corrosive work areas while keeping weight low for end-of-arm tooling. Delivering 56.5 N of push force at 0.5 MPa, this 12mm bore unit is both compact and quick.
This specific configuration includes a built-in piston magnet (S) for position sensing and a U-type back cover providing a 90-degree perpendicular 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 to decelerate the stroke, operating at speeds from 50-800 mm/s.

| 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 |

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 PB12X10SU Is Used
PCB Pick-and-Place
Drives a short 10mm eject motion in electronic assembly jigs where the slim stainless body clears adjacent tooling and the U-side inlet keeps hoses flat against the gantry.
Blister Pack Sealing
Provides a precise 10mm clamping stroke on a small sealing head, using the fixed TPU bumper to soften the final impact without requiring bulky external cushioning.
Lab Dispenser Actuation
Moves a micro-valve for chemical dosing in wet environments, relying on the SUS304 rod for corrosion resistance and the S magnet to trigger an electronic switch for dosing confirmation.
Is the Airtac PB Pen-type Cylinder PB12X10SU the Right Cylinder?
If you need less force, the 10mm bore version provides 39.3 N push at 0.5 MPa; stepping up to the 16mm bore yields 100.5 N push at 0.5 MPa for heavier tooling.
Because the 5mm rod is designed strictly for coaxial thrust, avoid side loads and add an external linear guide if the mechanism risks off-axis strain. Note that a plain PB body does not hold its position if air pressure drops or the valve centers, so install an external rod lock for fail-safe load holding. Confirm your ordering essentials: 12mm bore, 10mm stroke, M5x0.8 port, S magnet, U side inlet, and your required 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 PB12X10SU FAQ
This double-acting cylinder generates a push force of 56.5 N and a pull force of 46.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it yields 79.1 N push and 65.4 N pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s, with a proof pressure of 1.2 MPa.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the rod near the end of the stroke; it does not act as a brake. For vertical applications requiring fail-safe load holding, you must add an external stop or rod lock.
