Mounting bearings using heat

Induction HeaterIts functionequals thatofanelectric transformer.Withan inductioncoil,averyhighamperagewithalowvoltageisinducedintoaring-shapedwork-piece.Thereby,it isheatedconsistentlywithinminutes.Heatisonlyinducedto theworkpiecewhereas theheater itself remainsatambient temperatureand canbe touchedwithout riskatany time. The inductiveheating is veryefficient, as the workpiece is being heated directly with the inductive flow.Non-metallicpartssuchassealings,lubricantandcagesarenotheated.Theadvantageisthatthecoldbearingscanbelubricatedbeforemounting.Sinceinductively heated bearings become magnetised, the simatherm inductionheaters are always equipped with a demagnetisation unit. It prevents thebearingsfromattractingmetalparticleswhichcouldcauselong-termdamagetothebearing.

Mounting of the heated workpieceInordertomountabearingtoitsseat,aheatingtemperatureof110°C(�30°F)isrecommended.Highertemperaturesarenotnecessaryandmustbeprohi-bited.Temperatureshigherthan1�5°C(�57°F)cancausestructuralchangesofthebearingmaterial.Thebearingtemperaturemustthereforebeobservedwithatemperatureprobe.Shrinkcollarsorotherring-shapedparts,however,canbeheateduptoatemperatureofabout400°C(75�°F)withaninductionheater.

During mounting hot bearings, clean protective gloves must be worn.
