DRIVE CHAINS - Tsubaki

Corrosion Resistant Roller ChainsLow Noise Roller ChainsTsubaki’s uniquely structured spring rollers are used for the chain rollers. When Tsubaki’s Low Noise RollerChain engages the sprocket, the spring roller deforms and absorbs the force of impact, reducing impactnoise between chain and sprocket for lower noise levels. Compared with Tsubaki’s standard RS Roller Chain(pre-lubricated), noise levels of Low Noise Roller Chain are 6 - 8 dB lower. (In-house comparison testing)Benefits of noise reductionNoise level dB (A)Less factory noise for a better work environment.A low noise function is added to machinery and equipment used for manufacturing, and contributes to upgrading and improving their overall image.Belts were considered as a countermeasure for noise; however, there are many limitations in terms of application, strength and overall cost. LowNoise Chain is the perfect countermeasure.Recommended for applications where silence is a major concern, such as stage lifts used in theaters.85807570656050SprocketImpact noiseFeaturesLow noise50InterchangeabilityRollerStandard RS Roller Chain100 150Chain speed (m/min)Dimensional specifications are the same as for RS Roller Chain.Note: There are limits on drive power; check kW ratings tables on pgs. 109—111.SelectionUse the General Selection Method (the kilowatt ratings tables on pgs. 109—111).See selection pages for more details.Operating temperatures—10¡C to 60¡CAllowable chain speed200 m / min (max.)SprocketCan be used with standard RS sprockets.If the chain cannot be sufficiently lubricated, choosesprockets with hardered tooth tip specifications.For less noiseNoise levels reduced by 6 dB to 8 dB compared with the RS Roller Chain.In-house comparison of noise levelsRS50-1(RS Roller Chain)RS50-SNS-1(Low Noise Roller Chain)SprocketTest conditionsChain tension: 3.29 kNLubrication: Pre-lubrication onlymeasurement position: 300 mmfrom drive sprocketTest chainsRS50-SNS-1(Low Noise Roller Chain)RS50-1(RS Roller Chain)Spring roller (deforms)Lessens impact noiseLow Noise Roller ChainSpeed reducer w / motorDrivesprocketMeasurementdeviceBefore Use For Safe Use Standard Roller Chains Lube-Free Roller Chains Heavy Duty Roller Chains Corrosion Resistant Roller Chains Specialty Roller Chains Accessories Selection Handling108
