Airtac PB Pen-type Cylinder PB12X15R
The AirTAC Airtac PB Pen-type Cylinder PB12X15R 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 PB12X15R
The AirTAC PB12X15R is a JIS pen-size double-acting 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 weight to an absolute minimum. With a 12mm bore and 15mm stroke, it generates 56.5 N of push force and 46.7 N of pull force at 0.5 MPa.
This specific configuration includes an R axial air inlet for in-line plumbing and uses an M5x0.8 port. The Ø6-Ø16 bore range relies on a fixed TPU bumper at each end to decelerate the piston over the final few millimeters of travel. Because this bumper is not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving heavier tooling masses at high speeds.

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 PB12X15R Is Used
Blister Pack Sealing
Provides consistent downward pressure on a heat sealing head within a tight multi-cavity mold, where the SUS304 body resists humid packaging environments.
Micro-Dispense Valve
Triggers a precision fluid valve for adhesive application on electronic components, benefiting from the axial R inlet for flat, in-line plumbing on a crowded tooling plate.
Is the Airtac PB Pen-type Cylinder PB12X15R the Right Cylinder?
If you need slightly less force, the PB10X30 provides 39.3 N of push at 0.5 MPa; stepping up to the PB16X100 yields 100.5 N for heavier payloads.
Remember that the thin Ø5 mm piston rod is designed strictly for coaxial thrust, so utilize an external guide or linear bearing if side loads are present. A plain double-acting cylinder like this will drift and cannot hold a load if air pressure is lost or the valve is centered, meaning an external rod lock is necessary for fail-safe positioning. To order, confirm the 12mm bore, 15mm stroke, M5x0.8 port, R axial inlet, and the absence of a sensor magnet.
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 PB12X15R 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.
It uses a fixed TPU bumper at each end to decelerate the piston over the last few millimeters, which is not adjustable or field-tunable. Furthermore, it does not hold its position if air is lost; the piston will drift, so an external stop is required for fail-safe load holding.
