A study bearing rollers grinding disc material, continue to improve the surface quality of the rolling elements. NSK bearing company in 1997 had China's three ball factory production G5, G10 level Ball did research and quality testing, test results show that: the precision ball bearings in China and Japan comparable, but the surface of the ball quality texture uneven, corrugated peak large, than Japan's very weak, and that our ball retention metal plate research specific machining marks, which is telling us, non-metallic abrasive disk may be a more ideal processing veins, why do not we study these problems?

Second, the development of new grease. Supporting role grease noise reduction is very clear. NSK Bearings has developed a variety of low-fat vibration. In contrast our fat varieties pitiful. We should increase investment to develop not only can reduce the vibration and can extend the life of the dynamic performance of the grease.

Third, by chemical modification, to improve the surface quality of the rolling bearing, to reduce vibration and noise, while improving the performance of the bearing life. It refers to a chemically modified by chemical treatment of the work surface to form a chemical film, this process has made encouraging progress in the aviation engine bearings oil off test in terms of a foreign country, can be imagined to enhance the dynamic noise reduction and vibration reduction life will be a great benefit.

Fourth, the study vibration reduction, noise reduction, new cage, deep groove ball bearing cage for many years are ball pocket, self-guided wave-shaped cage, the radial clearance of its pocket and rolling elements, an axial gap at what is the best, the most favorable vibration reduction, the pocket-shaped spherical good, good or ellipsoid, shape or other good, never seriously studied in deep groove ball bearing vibration value requires more than Z3 group, irrespective Effect of vibration on the cage is not comprehensive.
