High quality ceramic ball bearing

Ceramic microstructures enjoy covalent bonding inherent between non-metal elements. This means they share electrons. This atomic co-operation yields a very strong attraction force and because of this, ceramics offer a series of benefits in comparison to metals.
* 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.
* Ceramics are non-metallic, nonferrous materials. They don’t corrode in the same way as metals when exposed to water and other hazardous chemicals. Their high degree of corrosion resistance allows them to perform excellently in wet and chemically-corrosive environments.
* Many engineering ceramics also have a low density leading to improvements in bearings’ operational speeds, which is due to low centripetal forces and reduced friction.
* Due to the lack of free electrons in most ceramics, they are non-magnetic and excellent insulators.
