Airtac PB Pen-type Cylinder PB6X10SRFA
The AirTAC Airtac PB Pen-type Cylinder PB6X10SRFA is a double-acting pen-size (mini) air cylinder with a Ø6mm 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 PB6X10SRFA
The AirTAC PB6X10SRFA is a double-acting JIS pen-size mini cylinder engineered for compact, high-frequency small-part motion. It features a slim SUS304 stainless steel round barrel and piston rod, providing excellent durability in damp or mildly corrosive environments without adding unnecessary bulk to your end-of-arm tooling. With a 6mm bore and 10mm stroke, it generates 14.2 N of push force and 10.6 N of pull force at 0.5 MPa.
This configuration includes a built-in piston magnet (-S) for compatibility with AirTAC reed or electronic switches, an R axial air inlet for in-line plumbing, and an FA mounting bracket. The M5x0.8 port and M5x0.8 rod-end thread are fixed by the bore size. It uses a fixed TPU bumper at each end to decelerate the stroke, operating effectively between 0.15-0.7 MPa at speeds of 50-800 mm/s.

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 PB6X10SRFA Is Used
PCB Probe Testing
Drives delicate test probes onto printed circuit boards in automated ICT fixtures, utilizing the short 10mm stroke and slim stainless body to maximize tester density.
Micro-Component Sorting
Pushes small electronic chips or resistors into designated tubes on a high-speed SMT line, where the FA bracket provides a stable bolted interface to the machine frame.
Lab Dispenser Actuation
Toggles miniature pneumatic valves for chemical dispensing in diagnostic equipment, benefiting from the fast 50-800 mm/s response and compact footprint.
Is the Airtac PB Pen-type Cylinder PB6X10SRFA the Right Cylinder?
When sizing this actuator, plan for a safe working load of about 9 N, which is roughly 60% of the 14.2 N theoretical push at 0.5 MPa, ensuring smooth travel after accounting for seal friction. For vertical lifts, this equates to raising approximately 0.7 kg with a sane 2:1 safety margin. If you need less force, note that the smaller 4mm bore offers 6.3 N push at 0.5 MPa, while stepping up to the 10mm bore provides 39.3 N push at 0.5 MPa.
Because the 3mm rod is designed strictly for coaxial thrust, avoid side loading and add an external linear bearing if guiding off-axis loads over the travel distance. A plain double-acting cylinder does not hold its position if air pressure drops or the valve is centered; the piston will drift, and the fixed bumper only decelerates near the stroke end. For fail-safe holding, integrate an external stop or rod lock. Confirm your ordering essentials: 6mm bore, 10mm stroke, M5x0.8 port, S magnet, R axial inlet, and FA mount.
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 PB6X10SRFA FAQ
This double-acting cylinder outputs 14.2 N push and 10.6 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it outputs 19.8 N push and 14.8 N pull. It operates between 0.15-0.7 MPa, handles speeds of 50-800 mm/s, and has a proof pressure of 1.2 MPa.
No, a plain double-acting PB cylinder will drift if air is lost or the valve is centered. The fixed TPU bumper at each end only decelerates the piston near the stroke limits; it does not act as a lock or brake. You must use an external rod lock or mechanical stop to hold a load safely.
