Airtac PB Pen-type Cylinder PB6X10RFA
The AirTAC Airtac PB Pen-type Cylinder PB6X10RFA 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 PB6X10RFA
The AirTAC PB6X10RFA 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, offering excellent durability in damp or mildly corrosive environments while keeping weight low for end-of-arm tooling. Delivering 14.2 N of push force at 0.5 MPa, this 6 mm bore unit uses an M5x0.8 port and a fixed TPU bumper at each end to decelerate the stroke.
This specific configuration includes an R axial air inlet for in-line plumbing and an FA mounting bracket for straightforward attachment. The Ø3 mm piston rod has an M5x0.8 rod-end thread for direct load coupling. Because the bumpers are fixed and not adjustable, metering out the exhaust or adding an external shock absorber is recommended when moving real tooling mass at higher speeds.

| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 10 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 |

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 PB6X10RFA Is Used
PCB Pick & Place
Drives a tiny vacuum gripper to lift and position delicate printed circuit boards within a dense electronics assembly fixture.
Label Dispensing
Advances a small peel blade in a packaging line to push adhesive labels onto lightweight plastic bottles.
Lab Sample Sorting
Actuates a diverter gate to route micro-tubes between testing carousels in clinical diagnostic equipment.
Is the Airtac PB Pen-type Cylinder PB6X10RFA the Right Cylinder?
When sizing this actuator, consider stepping down to the Ø4 bore if your payload is extremely light, or moving up to the Ø10 bore which provides 39.3 N of push at 0.5 MPa for heavier resistance. At 0.5 MPa, plan for a safe working load of about 9 N (roughly 60% of the theoretical 14.2 N figure) to account for seal friction and smooth travel. This equates to lifting about 0.7 kg vertically with a sane 2:1 margin.
A plain double-acting cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the bumper only decelerates near the stroke end. For fail-safe holding, an external stop or rod lock is required. To order, confirm the 6 mm bore, 10 mm stroke, M5x0.8 port, 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 PB6X10RFA FAQ
This 6 mm bore double-acting cylinder provides a push force of 14.2 N and a pull force of 10.6 N at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, the push force is 19.8 N and the pull force is 14.8 N. It operates at pressures from 0.15-0.7 MPa and speeds of 50-800 mm/s.
No, a standard double-acting pen-size cylinder drifts when air is removed or the valve is centered. The fixed TPU bumper only decelerates the piston near the end of the stroke; it does not act as a lock. You must add an external rod lock or mechanical stop to hold a load safely.
