Tsubaki Guide to Forestry Products

NEPTUNE DRIVE CHAINWhen durability really mattersNEP: The Science Behind TsubakiNeptune Chain provides corrosion protection that works better and lastslonger than ever before. Tsubaki’s exclusive NEP coating process is amulti-layer anti-corrosive shield that provides “best-in-class” protection.NeptuneAnti-Corrosive Drive ChainL1TφDL2hφRHTWL1L2CPPOLOLResin Top CoatingLLZinc/Aluminum CoatingZinc CoatingLonger LastingPIN/BUSHING/PLATESOTHER BRANDChain SurfaceZinc/Silica CoatingZinc CoatingROLLERChain SurfaceTHE RESULT OF SALT SPRAY TESTING – 500 HOURSOperating temperature rangeis between -10˚C~+150˚C.TSUBAKI NEP RS60ChainNumberPitchPRollerDia.DWidthBetweenInnerLinkPlatesWThicknessTLink PlateHeightHHeighthDia.DLengthL 1+L 2PinLengthL 140-60 NEPLengthL 2OffsetPinLengthL80-160 NEPTransversePitchCAll dimensions in inches unless otherwise stated.AverageTensileStrength(lbs.)MaximumAllowableLoad(lbs.)Approx.Weight(lbs./ft.)Single Strand60NEP 0.750 0.469 0.500 0.094 0.713 0.614 0.235 1.087 0.506 0.581 1.110 - 9,900 1,980 1.03 16080NEP 1.000 0.625 0.625 0.126 0.949 0.819 0.313 1.398 0.640 0.758 1.504 - 17,600 3,300 1.78 120100NEP 1.250 0.750 0.750 0.157 1.185 1.024 0.376 1.677 0.778 0.900 1.799 - 26,400 5,060 2.67 96120NEP 1.500 0.875 1.000 0.189 1.425 1.228 0.437 2.118 0.980 1.138 2.276 - 37,400 6,820 3.98 80140NEP 1.750 1.000 1.000 0.220 1.661 1.433 0.500 2.307 1.059 1.248 2.496 - 48,400 9,020 5.02 68Double Strand60NEP-2 0.750 0.469 0.500 0.094 0.713 0.614 0.235 1.988 0.955 1.033 2.071 0.898 19,800 3,360 2.04 16080NEP-2 1.000 0.625 0.625 0.126 0.949 0.819 0.313 2.551 1.217 1.335 2.657 1.154 35,200 5,610 3.53 120100NEP-2 1.250 0.750 0.750 0.157 1.185 1.024 0.376 3.091 1.484 1.606 3.209 1.409 52,800 8,602 5.26 96120NEP-2 1.500 0.875 1.000 0.189 1.425 1.228 0.437 3.906 1.874 2.031 4.063 1.787 74,800 11,590 7.84 80140NEP-2 1.750 1.000 1.000 0.220 1.661 1.433 0.500 4.232 2.022 2.211 4.421 1.925 96,800 15,334 9.94 68Numberof linksper 10feetTougher Than The Rest• Neptune’s innovative coating process avoids the use of high temperatures which can contribute to weakening of the chain’s components.• Neptune has the same load ratings as Tsubaki carbon steel chain, ensuring maximum performance.Neptune Lambda Drive ChainAnti-Corrosive Self-Lubricating Drive ChainLambda chain uses special oil impregnated bushings to providelubrication and to prolong wear life.L2 L1hT1φDφRT2HWLOLMaximum Allowable LoadCarbon SteelChain100%Neptune Chain100% Zinc-Tin AlloyCoated Chain84%Dacrotized®Zinc-AluminumCoated Chain100%Nickel PlatedChain84%Stainless Steel12%Note: The high temperature coating process that is used on Dacrotized® coated chain causes the chain to lose about 6% of its tensile strength.Chain NumberPitchPRollerDia.RWidthBetweenInnerLinkPlatesWThicknessT 1Link PlateThicknessT 2HeightHHeighthDia.DLengthL 1+L 2PPPinLengthL 1LengthL 2OffsetPinLengthLAll dimensions in inches unless otherwise stated.AverageTensileStrength(lbs.)MaximumAllowableLoad(lbs.)RS60 NEP LAMBDA 0.750 0.469 0.483 0.094 0.126 0.713 0.614 0.235 1.159 0.539 0.620 1.260 9,900 1,980 1.15 160 394RS80NEP LAMBDA 1.000 0.625 0.609 0.126 0.157 0.949 0.819 0.313 1.472 0.675 0.797 1.571 17,600 3,300 1.86 120 295RS100NEP LAMBDA 1.250 0.750 0.736 0.157 0.189 1.185 1.024 0.376 1.752 0.813 0.939 1.870 26,400 5,060 2.88 96 262RS120NEP LAMBDA 1.500 0.875 0.974 0.189 0.220 1.425 1.228 0.437 2.193 1.014 1.179 2.323 37,400 6,820 4.29 80 164RS140NEP LAMBDA 1.750 1.000 0.974 0.220 0.252 1.661 1.433 0.500 2.358 1.091 1.268 2.508 48,400 9,020 5.43 68 164Approx.Weight(lbs./ft.)Numberof linksper 10feetMaximumAllowableSpeed (ft./min.)18 19
