Advantages and disadvantages of cycling ceramic bearings

We can't live without some mechanical equipment, because it is part of our life.Bearing is a mechanical machine and so on an important basic parts, but the bearing is also a lot of materials, different materials applicable to mechanical equipment will have a certain difference, cycling ceramic bearings perhaps we are not familiar with, so ceramic bearing advantages and disadvantages are what?With metal bearing presumably, ceramic bearing or metal bearing good?Now let's explain.
Advantages and disadvantages of cycling ceramic bearings:

Cycling ceramic bearing atomic structure, non - metallic inherent covalent bond.This means that they share electrons, the atoms have a strong adsorption, and for this reason, cycling ceramic bearings provide some better performance than metal bearings.They are usually very hard, elastic and light.This means that the load is applied in conjunction with improved wear resistance when the shape changes.
Cycling ceramic bearings operate without lubrication.This is because ceramic materials are not micro-welded.Microwelding occurs, usually with metal, when a defect on the surface of the rolling element and raceway interacts with another causing arc.This reduces the surface and significantly reduces the life of the bearing.Ceramic materials do not have this problem, which makes them suitable for a variety of applications that require a free lubricating environment.They're usually at high temperatures which means there's less thermal expansion acting in a stable way.

Cycling ceramic bearings are nonmetallic, nonferrous materials.When exposed to water and other harmful chemicals they do not corrode in the same way as metals.Their high corrosion resistance allows them to perform well in wet and chemically corrosive environments.Many engineered ceramics also have a low density, resulting in a bearing 'working speed, which is improved due to low centripetal force and reduced friction.Due to the lack of free electrons in most cycling ceramic bearings, they are non-magnetic and excellent insulators.When studying cycling ceramic bearings, the first thing one might notice is that they are basically more expensive than metal.
