Advantages:
    A small frictional resistance, Ball Bearings small power consumption, mechanical efficiency, easy starting;
  2, size standardization, interchangeability, ease of installation and removal, maintenance;
  3, compact, light weight, the axial dimension is more narrow;
  4 high accuracy, high speed,Ball Bearings  low abrasion and long service life;
  5, some with self-aligning bearing performance;
  6, suitable for mass production, reliable quality, high efficiency
Disadvantages:
   1, noisy
    2, more complex bearing structure
    3, higher costs
Rolling and sliding bearings in comparison, Ball Bearings with the following advantages:
     1. Rolling friction coefficient smaller than the sliding bearing, high transmission efficiency. General Bearing friction coefficient of 0.08-0.12, Ceramic Bearings while the Rolling friction coefficient was 0.001-0.005;
     2. Rolling has been standardization, serialization, universal, suitable for mass production and supply, use and maintenance is very convenient;
   3. Rolling with the bearing steel, and after heat treatment, therefore, bearing not only has high mechanical performance and long service life, but it will save manufacturing plain bearings are used in more expensive non-ferrous metals;
     4. Bearing internal clearance is very small,Ball Bearings  high precision machining of parts, therefore, high precision operation. At the same time, Ceramic Bearings you can add pre-load method to increase the bearing stiffness. This is precision machinery is very important;
     5. Some of the bearing can support radial load and axial load, therefore, can simplify the structure of the bearing supports;
     6. As the bearing drive, high efficiency, less heat and therefore can reduce the consumption of lubricants and lubrication to maintain more save trouble;
     7. Rolling can be easily applied to any position of the uranium on the space.
However, all things are divided into two, Ball Bearings and bearing also has some shortcomings, mainly:
     1. Rolling bearing load capacity than the same volume of plain bearings is much smaller, therefore, the radial bearing large size. So, Ceramic Bearings bear big occasions and requirements of the radial load is small, Ceramic Bearings compact structure, required occasions <such as crankshaft bearings), and more use of plain bearings;
     2. Large rolling bearing vibration and noise, especially late particularly notable in the use, therefore, demanding precision, not Xuyou Zhen moving occasion, bearing hard competent, general use and even better sliding bearing
     3. Rolling of metal debris and other foreign bodies are particularly sensitive, bearing Once foreign body, will result in large intermittent vibration and noise, Ball Bearings will lead to early damage. In addition,Ball Bearings  the bearing due to impurities such as metal clips are also prone to the possibility of early damage. Even if the damage does not occur early, the life of rolling bearings there are certain limits. In short, the rolling bearing life shorter than the sliding bearing.
   However, compared Rolling and sliding bearings, each with advantages and disadvantages for each share certain occasions, Ceramic Bearings so the two can not completely replace each other, Ceramic Bearings and each to a certain direction, to expand their field. However, due to the outstanding merits of Rolling, who was home on quite a trend. At present, the rolling bearing has developed into a major bearing types of machinery, more and more applications.
