Airtac PB Pen-type Cylinder PB6X15SR
The AirTAC Airtac PB Pen-type Cylinder PB6X15SR is a double-acting pen-size (mini) air cylinder with a Ø6mm 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 PB6X15SR
The AirTAC PB6X15SR is a double-acting JIS pen-size mini cylinder engineered for high-frequency small-part motion. It supplies 14.2 N of push and 10.6 N of pull at 0.5 MPa, utilizing a slim SUS304 stainless steel barrel and a 3 mm rod to fit tight jigs and light end-of-arm tooling where larger bodies cannot. The M5x0.8 port and M5x0.8 rod-end thread simplify in-line plumbing and load coupling.
Because this configuration includes the S option, a built-in piston magnet enables position detection using AirTAC reed or electronic switches. The R axial inlet supports straight-line air connections, while fixed TPU bumpers at each end absorb end-of-stroke impact. Plan for a safe working load of roughly 9 N (about 60% of the 0.5 MPa theoretical force) to account for seal friction and smooth travel.

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 (Ø6mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 14.2 N | 10.6 N |
| 0.7 MPa (max) | 19.8 N | 14.8 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 PB6X15SR Is Used
PCB Probe Testing
Drives delicate test probes onto circuit boards with a safe working load near 9 N, ensuring accurate contact without damaging the substrate.
Micro-Component Sorting
Actuates tiny diverter gates on chip placement lines, using its built-in S magnet to confirm gate position via solid-state switches.
Lab Dispenser Positioning
Moves precision fluid dispensing needles in analytical instruments, capitalizing on the SUS304 stainless body for damp environment durability.
Is the Airtac PB Pen-type Cylinder PB6X15SR the Right Cylinder?
This 6 mm bore generates 14.2 N push at 0.5 MPa. If your task needs less force, the 4 mm bore offers 6.3 N; if you need more clamping power, stepping up to the 10 mm bore provides 39.3 N. Confirm your ordering essentials: 6 mm bore, 15 mm stroke, M5x0.8 port, S magnet for sensors, and R axial inlet.
A plain double-acting cylinder drifts when air is lost or the valve is centered, as the internal bumper only decelerates the piston near stroke end rather than locking it. For vertical or fail-safe load holding, you must add an external stop or rod lock. Furthermore, the slender 3 mm rod is designed strictly for coaxial thrust, so utilize an external linear bearing if the application involves any off-axis loading.
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 PB6X15SR FAQ
At 0.5 MPa, the push force is 14.2 N and the pull force is 10.6 N. At the maximum operating pressure of 0.7 MPa, the push is 19.8 N and the pull is 14.8 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumper only decelerates the piston over the last few millimeters of stroke; it does not act as a brake. An external rod lock or mechanical stop is required for fail-safe load holding.
