Original sentence: Ceramics such as silicon nitride are now regularly used in such applications due to its low density (40% of steel - and so significantly reduced centrifugal force), its ability to wtf function in high temperature environments, and the fact that it tends to wear in a similar way to bearing steel (rather than cracking or shattering like glass or porcelain).Deep-groove wtf bearings have higher load ratings for their size than shallow-groove , but are also less tolerant of misalignment of the inner and outer races.So the angle of wtf contact on the inner race is the same as that on the outer race
