Airtac PB Pen-type Cylinder PB12X15U
The AirTAC Airtac PB Pen-type Cylinder PB12X15U is a double-acting pen-size (mini) air cylinder with a Ø12mm bore and 15mm 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 PB12X15U
The AirTAC PB12X15U is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel barrel and piston rod, offering excellent durability in damp or mildly corrosive environments while keeping end-of-arm tooling exceptionally light. Delivering 56.5 N of push force at 0.5 MPa, it integrates a U-type back cover that provides a 90-degree side air inlet for flat plumbing in space-constrained machinery.
This 12 mm bore unit uses an M5x0.8 port and a 5 mm rod with an M10x1.0 rod-end thread. It operates at speeds from 50-800 mm/s and relies on a fixed TPU bumper at each end to decelerate the stroke. Because the bumper is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving heavier tooling masses at higher velocities.

| Bore size | Ø12 mm |
| Rod diameter | Ø5 mm |
| Stroke | 15 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 PB12X15U Is Used
Blister Pack Sealing
Presses a heated die down onto blister card stock, utilizing the flat 90-degree U inlet to keep pneumatic plumbing flush against the compact packaging frame.
Micro-Pick Head
Drives a tiny vacuum gripper on a pick-and-place unit, with the SUS304 body resisting flux fumes and washdown moisture in electronics assembly.
Is the Airtac PB Pen-type Cylinder PB12X15U the Right Cylinder?
If you need to step down, the Ø10 bore provides 39.3 N of push at 0.5 MPa; stepping up to the Ø16 bore yields 100.5 N. To finalize your order, confirm the 15 mm stroke, M5x0.8 port, U 90-degree side inlet, and the absence of a sensor magnet. 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 holding.
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 PB12X15U FAQ
This double-acting cylinder delivers a push of 56.5 N and a pull of 46.7 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it provides 79.1 N of push and 65.4 N of pull. It operates between 0.15-0.7 MPa at speeds of 50-800 mm/s.
No, a plain PB cylinder does not hold its position or load when air is lost or the valve is centered; the piston will drift. The fixed TPU bumper only decelerates the rod near the stroke end and does not act as a lock. An external stop or rod lock is required for fail-safe holding.
