Airtac PB Pen-type Cylinder PB6X5R
The AirTAC Airtac PB Pen-type Cylinder PB6X5R is a double-acting pen-size (mini) air cylinder with a Ø6mm bore and 5mm 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 PB6X5R
The AirTAC PB6X5R is a double-acting JIS pen-size mini cylinder engineered for short-stroke small-part handling. It provides 14.2 N of push and 10.6 N of pull at 0.5 MPa, driven through an M5x0.8 port. The slim SUS304 stainless barrel and Ø3 mm rod keep mass low for high-speed end-of-arm tooling.
This variant features an R axial air inlet for clean in-line plumbing. End-of-travel deceleration relies on a fixed TPU bumper at each end, which is not adjustable. Because the rod is only 3 mm thick, you should maintain coaxial alignment and avoid side loads to prevent bending.
Airtac PB Pen-type Cylinder PB6X5R Technical Specifications
| Model | Airtac PB Pen-type Cylinder PB6X5R |

| Series | PB JIS pen-size mini cylinder |
| Bore size | Ø6 mm |
| Rod diameter | Ø3 mm |
| Stroke | 5 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 PB6X5R Is Used
Micro-clip insertion
Pushes delicate electronic clips into PCB sockets with a 9 N safe working load, preventing overdrive on sensitive assemblies.
Light panel ejection
Ejects small plastic trim pieces from machining fixtures using the 5 mm stroke, relying on the TPU bumper to soften the final impact.
Tube diverter gate
Shifts a lightweight pneumatic routing flap in packaging lines, where the compact SUS304 body resists occasional wash-down moisture.
Is the Airtac PB Pen-type Cylinder PB6X5R the Right Cylinder?
For sizing context, stepping down to a Ø4 bore yields 6.3 N of push at 0.5 MPa, while stepping up to a Ø10 bore provides 39.3 N. This Ø6 model offers a safe working load of roughly 9 N (about 60% of its 14.2 N theoretical output) and can vertically lift approximately 0.7 kg with a 2:1 safety margin. Note that a plain cylinder drifts when air is lost; an external rod lock is required for fail-safe holding.
When ordering this configuration, confirm the 6 mm bore, 5 mm stroke, M5x0.8 porting, and the R axial inlet. It ships without a sensor magnet, and the fixed bumpers are suitable for standard speeds up to 800 mm/s.
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 PB6X5R 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, push is 19.8 N and pull is 14.8 N. The operating pressure range is 0.15-0.7 MPa, with a speed range 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 rod near the stroke end and does not act as a lock. For vertical load holding, you must add an external stop or rod lock.
