Bearing industry, "15" Development Plan determine the overall Chinese bearing industry development objectives, as determined by any technical research
 
There are two main tasks, one is to increase bearing life and reliability, and second roller bearing vibration and noise reduction. For the rolling elements,
 
"Fifteen" key task is focused around two major bearing research and careful analysis of the manufacturing level and quality of the rolling elements
 
Level for main factors influencing bearing life vibration and noise, to solve key manufacturing technology of rolling elements, and the bearing system
 
Work closely with manufacturing plants to raise the overall quality of the rolling elements, roller bearings achieve vibration and noise reduction, improving bearing life and
 
reliability.
     
      In the rolling element product level, quality level, the level of equipment and testing instruments and testing methods level, and grinding

     The Survey on the basis of abrasive material, tooling and grinding fluids, etc., aimed at the manufacturing level and professional rolling element exists
 
Issue, the rolling element technology research to be carried out and measures taken.
     
      2, improve the life and reliability of the rolling elements
     
      2.1 Status rolling element life abroad
     
      Effect of rolling element bearing life in theory ranked No. 2 behind the inner ring, bearing the national quality supervision and inspection
 
Nearly three years of supervision inspection center life test,

      Rolling element bearing failures destroy accounted ploidy rates were: the development of network-based technologies;

     (25) roller eddy current flaw detector development;

     (26) roller Appearance instrument development;

     (27) roller projection measuring instrument development.
     
     3.4.4 related technologies
     
     (28) the development of new mold material;

     (29) the development of new grinding fluids;

     (30) dried coating roller cleaning demagnetization develop oil-line equipment;
     (31) the development of efficient roller polisher machine;

     (32) the development roller surface hardening machine;

     (33) shot peening machine roller efficient development.
     
     4 Summary
     
     In terms of rolling element compared to the level of quality, technological level, the level of equipment and testing instruments and other foreign advanced level,
 
There are still gaps, with the rolling bearing precision, long life, low noise and high reliability requirements of increasingly high, the need
 
According to the current quality level of domestic rolling elements, one by comparison with the international advanced level, the development of related measures on key technologies
 
Organization of joint research, increase innovation, speed up specialized organizational restructuring, as soon as possible to cultivate a group of a certain size
 
Specialized rolling the production of key enterprises, the key to solve the rolling element manufacturing technology, greatly improve the overall quality of the rolling elements,
 
Rolling vibration and noise reduction to achieve the goal of contributing to improving life.
