Manufacturer: ABB
Lubricationintervalsforverticalmachinesarehalfofthe
abovevalues.
Theamountofgreasestatedinthetableshouldbedoub-
ledifanautomaticregreasingsystemisused.
Thetablevaluesarebasedonthemotorrunningatrated
outputinanambienttemperatureofabout+25°C(approx.
80°Cbearingtemperature).Thevaluesshouldbehalved
for15°Cincreaseinbearingtemperatureandmaybe
doubledfor15°Cdecreaseinambienttemperature.
Higherspeedoperation,eginfrequencyconverterapplica-
tions,orlowerspeedwithheavyloadwillrequireshorter
lubricationintervals.ConsultABBSalesOfficeinsuchcases.
Typicallyadoublingofspeedwillrequireareductionof
lubricationintervalstoapprox.40%ofvaluestabulated
above.
Suitabilityofbearingsforhighspeedoperationmustalsobe
checked.
WARNING!
 Themaximumoperatingtemperature
 ofthegreaseandbearingsmustnotbe
 exceeded.
Lubricants
Whenregreasing,useonlyspecialballbearinggrease
withthefollowingproperties:
- goodqualitygreasewithlithiumcomplexsoapand
 withmineral-orPAO-oil
- baseoilviscosity100-150cSTat40°C
- consistencyNLGIgrade2or3
- temperaturerange-30°C-+120°C,continuously.
Greasewiththecorrectpropertiesisavailablefromall
themajorlubricantmanufacturers.
Thefollowing(orsimilar)highperformancegreasecan
beused
• EssoUnirex N2orN3
• Shell AlbidaEMS2
• SKF  LGHQ3
• Mobil MobilithSHC100
• Klüber KluberplexBEM41-132
• BP  EnergreaseLC2
 NOTE!
 Alwaysusehighspeedgreaseforhighspeed
 machinensandsomeothermodels,e.g.M2_355
 and4002-polemachines,wherethespeedfactoris
 higherthan400000(calculatedasDmxnwhere
 Dm=averagebearingdiameter,mm;n=rotational
 speed,rpm).Thefollowing,orsimilar,typesof
 greasecanbeused:
• Kluber AsonicGHY72
• Kluber AsonicHQ72-102
• Shell AlbidaEMS2
• Esso  LT2
• Mobil MobilithSHC100
Thefollowingnormaltypeofgreasecanbeusedifthe
regreasingintervalishalved(thesetypesofgreaseshould
notbeusedwhenbearingtemperatureisabove100°C).
• Esso  Beacon2or3
• Shell AlvaniaRL2orRL3
• SKF  LGMT2or3
• Mobil Mobilux2
• Kluber Centoplex2
• BP  EnergreaseLS2
Ifthemakeofgreaseischangedandcompatibilityis
uncertain,consultABBSalesOffice.
Highlyloadedand/orslowlyrotatingbearingsrequire
EPgrease.
Iftheambienttemperatureisbelow-25°Corabove
+55°C,orbearingtemperatureisabove110°C,consult
ABBSalesOfficeregardingsuitablegrease.
