LAMBDA SELF-LUBRICATINGDRIVE CHAINApplication: Star FeederSavings: $5,557.00Tsubaki solution: Previous chain elongated due to lack of maintenance/lubrication. Chain failedcausing downtime after 2 months. Self-lubricated Lambda lasted 30 months.It really mattered to this Tsubaki customerCOST SAVINGS!Lambda chain increases productivityand saves money.RS Single Pitch Lambda Drive Chain• Reduce maintenance time.• Eliminate product contamination.• Reduce downtime.L1L2T1φDφRhHT2LLWPP#40 to #80 #100 to #140L1Special Oil-ImpregnatedBushingL2CRollerLambda Chain (Std.): Inner/Outer plates are black oxideLambda Chain (Nickel Plated): All nickel-plated (except bushings)Long life and low maintenanceLambda chains use special oil-impregnated bushings to providelubrication and to prolong wear life.Ambient Temperature: -10 o C to +60 o C (+14 o F to +140 o F)0.5Wear Elongation (%)0ASME (ANSI) Standard RSRoller ChainOperation TimeLambdaMore than 14 times the wear elongation life of ASME (ANSI) Standard Roller Chain(N.B. #120 and #140 have 5 times the life of ASME (ANSI) Standard RS Drive Chain).InterchangeableLambda chain isinterchangeable with ASME(ANSI) standard drive chain.However, as the pins are longerthan that of Standard RS RollerChain, please make sure thatthere is no interference withthe machine.OperatingTemperature-10 O C to +150 o C(+14 o F to +302 o F)SprocketFor single strand, ASME (ANSI)Standard Roller Chain can beused.
