Airtac PB Pen-type Cylinder PB6X10SRLB
The AirTAC Airtac PB Pen-type Cylinder PB6X10SRLB 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 PB6X10SRLB
The AirTAC PB6X10SRLB is a JIS pen-size double-acting single-rod mini cylinder engineered for compact, high-frequency motion. It delivers a theoretical push of 14.2 N and pull of 10.6 N at 0.5 MPa, making it suitable for light-duty jig actuation. The slim SUS304 stainless barrel and piston rod provide reliable durability in damp or mildly corrosive environments without adding excessive mass to end-of-arm tooling.
This specific configuration includes an R axial air inlet for in-line plumbing and an LB mounting bracket for secure body attachment. Air connections use an M5x0.8 port, while the Ø3 mm rod features an M5x0.8 rod-end thread for straightforward load coupling. Because the bore is only 6 mm, the rod is designed strictly for coaxial thrust; avoid side loading or add an external linear bearing to prevent bending over longer extensions.

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 PB6X10SRLB Is Used
PCB Probe Testing
Drives delicate spring-loaded test pins against circuit boards in automated ICT fixtures, utilizing the short 10 mm stroke and precise 9 N safe working load to verify contacts without damaging traces.
Small Part Ejection
Pushes lightweight plastic components out of machining centers on conveyor lines, where the compact SUS304 body resists coolant mist and the LB bracket mounts flush to the machine frame.
Lab Dispenser Actuation
Toggles micro-valves or pushes syringe plungers in analytical instruments, benefiting from the pen-size footprint and R axial inlet that keeps pneumatic tubing neatly routed in tight enclosures.
Is the Airtac PB Pen-type Cylinder PB6X10SRLB the Right Cylinder?
When sizing this actuator, plan for a safe working load of roughly 9 N, which is about 60 percent of the 14.2 N theoretical push at 0.5 MPa, to account for seal friction and smooth travel. For vertical lifts, this equates to raising approximately 0.7 kg safely with a 2:1 margin. If you need less force, step down to the Ø4 bore, but if your payload exceeds these limits, consider stepping up to the Ø10 bore, which provides 39.3 N of push at 0.5 MPa.
This PB6X10SRLB configuration features a 10 mm stroke, an M5x0.8 port, an integrated S magnet for position sensing, an R axial inlet, and an LB mount. Note that a standard double-acting cylinder does not hold its position if air pressure is lost or the valve is centered; the piston will drift, and the fixed TPU bumper only decelerates it near the end of the stroke. An external rod lock is required for fail-safe holding.
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 PB6X10SRLB 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 is 19.8 N and the pull is 14.8 N. The operating pressure range is 0.15-0.7 MPa, with a speed of 50-800 mm/s and a proof pressure of 1.2 MPa.
No, a plain double-acting cylinder drifts if air is lost or the valve is centered; you need an external rod lock for fail-safe holding. For deceleration, Ø6-Ø16 models use a fixed TPU bumper at each end that absorbs impact over the last few millimeters. It is not adjustable, so for higher speeds or heavy tooling mass, meter-out the exhaust or add an external shock absorber.
