coussinet en céramique

CONT: L'axe de la pompe en acier inox est pourvu de coussinets en céramique presque inusables.

CONT: Ceramic bearings are attractive for use in gas-turbine engines because ceramics generally retain their strengths and resistances to corrosion over a range of temperatures much greater than that of typical steels used in rolling-element bearings. Furthermore, because ceramics have mass densities lower than those of steels, they might be used to reduce centrifugally induced stresses in the outer races of high-speed bearings.
