PB6X5-SR Pen-Type / Pencil-Type Compact CylinderThe PB6X5-SR is a highly compact, single-acting spring-return “pen/pencil” cylinder from AirTAC’s PB series. With its tiny footprint and short stroke, it is ideal for applications where space is very tight and small precise actuation is needed. Often used in assemblies, instruments, or devices needing small movements with consistent, reliable return.Key FeaturesSingle-acting, spring-return design — extends with air, retracts via spring.Very small bore & stroke (6 mm bore × 5 mm stroke) for precision micro-actuation.Stainless steel piston rod & compact / round body, good for corrosion resistance and durability.JIS standard cylinder series (compact design, lightweight) for miniaturized usage.Spring retract, usually with a rubber/spring buffer to absorb end-of-stroke impact.SpecificationsParameterDetailsModelPB6X5-SRType / ActingSingle-acting, spring returnBore Size6 mmStroke Length5 mmOperating Pressure~0.15 to 0.8 MPa (≈1.5 to 8 bar)Port / Thread SizeM5 threadBody MaterialAnodized aluminum alloyRod MaterialStainless Steel (SUS304)Seal MaterialNBR (nitrile rubber)Temperature Range-20 °C to 80 °CMountingFront mounting (often via front cover) — limited mounting optionsDimensions~16 mm × 16 mm × 41.5 mm (retracted)Weight~0.12 kg (without accessories)Max Speed / ResponseUp to ~500 mm/s (depending on load)ApplicationsHere are some typical uses for PB6X5-SR:Small precision devices (e.g. PCB component inserters)Actuation in medical equipment where travel is tiny and cleanliness/corrosion resistance mattersOptical / lens positioning or sensor triggeringLight-duty automation tasks where weight and space are constrained SKU: PB6X5-SR Categories: Industrial Automation, Pneumatic Components
