Description
They normally have a very high hardness (70-90 HRc) and elastic, or Young’s, modulus. This means they are resistant to shape change when loads are applied along with improved wear characteristics.
Ceramic bearings can run lubrication free. This is because ceramic materials don’t micro-weld. Micro-welding happens, typically with metals, when the surface imperfections on the rolling element and raceway interact with one another causing an electric arc. This degrades the surface and substantially reduces the bearing life. Ceramic materials do not have this issue which makes them suitable for various applications which require a lube-free environment.
They usually behave in a stable manner at high temperatures meaning there is less thermal expansion. It takes a great deal more energy to increase the bond length of a covalent bond in comparison to a metallic ionic bond.
