X-life ultra BearingsX-life ultra bearings were designedfor maximum demands on speedabilityand load. They are hybridbearings with rolling bearing ringsmade of Cronidur 30, a high nitrogenstainless steel. Compared tothe conventional rolling bearingsteel 100Cr6, Cronidur 30 exhibitsa substantially finer structure, thusensuring cooler operation andhigher admissible contact pressure.Basically, all spindle bearing designsare available as X-life ultrabearings.Compared to standard bearings,the extended service life of X-lifeultra bearings contributes to thereduction of system costs. However,achieving the full performancecapability of X-life ultra bearingsrequires a corresponding designof the surrounding structure (Picture5).5: X-life ultra bearingsSpindle Bearing CodeAll spindle bearings show a uniformcode (Picture 4). In additionto the information about the bearingdesignation this includes importantinformation on• the tolerance of inner ring boreand outside diameter• the bearing width. This is a newpiece of information.• the mounting direction, throughmarking on outer ring surface.This information offers the installationengineer support for a wellaimedmatching of bearings andshaft or housing.Details on the bearing code can bederived from the nomenclature(spindle bearings) in the appendix.FAG · 11
