Airtac PB Pen-type Cylinder PB6X5SR
The AirTAC Airtac PB Pen-type Cylinder PB6X5SR 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 PB6X5SR
The AirTAC PB6X5SR is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency small-part motion. At 0.5 MPa it generates 14.2 N of push and 10.6 N of pull force. The slim SUS304 stainless barrel and piston rod provide reliable durability in damp or mildly corrosive environments, while keeping weight low for end-of-arm tooling. This specific configuration includes an R axial air inlet for in-line plumbing and a built-in piston magnet.
Air enters via an M5x0.8 port to drive the Ø3 mm rod, which features an M5x0.8 rod-end thread for secure load coupling. End-of-stroke deceleration relies on a fixed TPU bumper at each end rather than an adjustable air cushion. Because the bumper only absorbs energy over the final few millimeters, high-speed cycles with real tooling mass may require metering out the exhaust or adding an external shock absorber.

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 PB6X5SR Is Used
Pick-and-Place Ejector
Short 5 mm ejection strokes on PCB assembly lines where the slim body fits between dense component arrays and the 14.2 N force easily pushes lightweight connectors.
Lab Dispenser Pinch Valve
Actuates a small pinch valve for chemical dosing, using the SUS304 stainless construction to resist humidity and the R axial inlet to keep plumbing flat against the machine frame.
Micro-Clamp Actuator
Provides a 5 mm clamping micro-stroke for holding thin film or foil in packaging machinery, relying on the built-in magnet to trigger a solid-state switch at stroke end.
Is the Airtac PB Pen-type Cylinder PB6X5SR the Right Cylinder?
When sizing this 6 mm bore actuator, plan for a safe working load of about 9 N at 0.5 MPa, which accounts for roughly 60% of the theoretical 14.2 N push force to overcome seal friction and ensure smooth travel. If your application requires slightly less power, the 4 mm bore offers 6.3 N of push at 0.5 MPa. Stepping up to the 10 mm bore provides 39.3 N of push at 0.5 MPa for heavier tasks. Keep in mind that a plain PB cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, so an external stop or rod lock is required for fail-safe holding.
To order this exact unit, confirm the 6 mm bore, 5 mm stroke, M5x0.8 air port, built-in S magnet for position sensing, and R axial back cover inlet. The thin Ø3 mm rod is designed strictly for coaxial thrust, so avoid side loads or add an external linear bearing if guidance is needed.
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 PB6X5SR FAQ
This double-acting cylinder delivers 14.2 N push and 10.6 N pull at 0.5 MPa. At the maximum operating pressure of 0.7 MPa, it provides 19.8 N push and 14.8 N pull. It operates at speeds from 50-800 mm/s, with a proof pressure of 1.2 MPa and a temperature range of -20 to +70 C.
No, the piston will drift if air is lost or the valve is centered. The fixed TPU bumpers only decelerate the rod near the stroke end and do not act as a brake. For vertical loads requiring fail-safe holding, you must add an external rod lock or mechanical stop.
