Please avoid this set up as much as possible.Compared to single-strand chain, the inner link of multi-strand chain is slightly less corrosive resistant. (In-house testingresults)105
Corrosion Resistant Roller Chains Surface-Treated Drive ChainsAPP SpecificationOutstanding performance in atmospheres conducive to pitting corrosionOpposite side of worn surfaceInitiation pointWorn surfacePins are treated with a special surface treatment toprotect against pitting corrosion that leads to fatiguebreaks, thus preventing strength loss. This treatmentis highly effective in environments that readily promotecorrosion, such as outdoors or coastal applications.Note: Pitting is a type of localized corrosion affecting metal surfaces. Pits form toward the interior, and if pitting occurs on pin surfaces, that pin can quickly leadto fatigue breakage and chain failure.Features No strength loss! Eco-friendly chrome-free!Same as standard steel chain.Example applicationsSpecial surface treatment does not use hazardoushexavalent chrome.APP Chains are ideal for atmospheres that readily promote corrosion.Outdoor uses Coastal or riverside uses When regular lubrication is difficultBucket elevatorsTransfer cranes and other port machineryExamples of fatigue breaks caused by pitting corrosionChain: RS240Applicable modelsChain numberBecause equipment is used outdoors,rain can infiltrate gaps in covers, creatingconditions that promote pitting corrosion.Equipment: Port container carrierPitting readily occurs in equipmentexposed to salty air or saltwater spray.Pitting corrosion of the pin due to insufficient lubrication (effects of salty air and saltwater) and corrosive atmosphere - - Fatigue breakageEnlarged viewof fracture surfaceSingle/Double Strand RS Roller ChainPin breakagePitting corrosion readilyoccurs on the opposite sideof the bush wear surface.Enlarged viewof breakageStarting pointPitting was observed inmore than one location.Single Strand Heavy Duty Roller ChainExcept for the surface-treated pins, dimensions and other specifications are the same as other roller chains.Secondary fracture in link plateLoad can become imbalancedafter pin breakage, leading tosecondary breaks in plates.(For other models, contact <strong>Tsubaki</strong>.)Before Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection HandlingNote: Select connectinglink (CL).Anti-Pitting Roller Chain106
