Airtac PB Pen-type Cylinder PB6X15SRFA
The AirTAC Airtac PB Pen-type Cylinder PB6X15SRFA 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 PB6X15SRFA
The AirTAC PB6X15SRFA is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency motion. It features a 6mm bore and a 15mm stroke, generating 14.2 N of push force and 10.6 N of pull force at 0.5 MPa. The slim SUS304 stainless steel barrel and piston rod provide excellent durability in damp or mildly corrosive environments while keeping mass low for end-of-arm tooling. This configuration includes an FA mounting bracket and an R axial air inlet for in-line plumbing.
Equipped with a built-in piston magnet (-S), this unit supports AirTAC reed or electronic switches for precise position detection. The M5x0.8 port and M5x0.8 rod-end thread simplify integration. It operates at 50-800 mm/s with a fixed TPU bumper at each end to decelerate the stroke. Because the bumper is non-adjustable, adding an external shock absorber is recommended for high-energy loads.

| Bore size | Ø6 mm |
| Rod diameter | Ø3 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 (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 PB6X15SRFA Is Used
PCB Pick-and-Place
Drives a tiny vacuum nozzle in a tight electronics assembly cell, using the FA bracket to bolt directly onto the moving carriage.
Lab Dispenser Actuation
Moves a micro-valve for chemical dosing where the SUS304 body resists humid cleanroom atmospheres and the compact 15mm stroke delivers precise drops.
Light Sorter Diverter
Pushes small plastic caps on a conveyor guide rail, relying on the built-in magnet to confirm the retracted position before the next part arrives.
Is the Airtac PB Pen-type Cylinder PB6X15SRFA the Right Cylinder?
If you need less force, the Ø4 bore offers 6.3 N of push at 0.5 MPa. If your application requires more power, stepping up to the Ø10 bore provides 39.3 N of push at 0.5 MPa.
This PB6X15SRFA configuration specifies a 6mm bore, 15mm stroke, M5x0.8 port, an S magnet for sensing, an R axial inlet, and an FA foot bracket. Note that a standard PB cylinder does not hold its position if air pressure is lost; the piston will drift, so an external rod lock is necessary for fail-safe holding. Additionally, the 3mm rod is built for coaxial thrust, so avoid side loads or add an external guide to prevent bending.
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 PB6X15SRFA 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 force is 19.8 N and the pull force is 14.8 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 field-adjustable. The -S code indicates a built-in piston magnet that allows you to mount AirTAC reed or electronic switches along the barrel for position detection.
