    Our deep groove sealed ball bearings and foreign companies with advanced internal structural parameters are almost the same, However, such products in China vibration and noise levels are different from foreign products, mainly in manufacturing and working conditions and factors. Considered from the perspective of the bearing industry, working conditions factors can be reasonably requested by the host to resolve how to reduce vibration and noise caused by the manufacturer of factors bearing industry must be addressed. bearing factory
    
    At home and abroad a large number of experiments show that: have different effects on processing quality of the cage, ring, ball bearing vibration, the processing quality of the ball is the most significant impact on bearing vibration, followed by the processing quality of the rings, the most important influence The roundness of the ball and rings, waviness, surface roughness, surface bump injury.
    
    Steel ball products in China is the most prominent problem is the vibration value of discrete, serious surface defects (single point, the group points, pits, etc.), surface roughness, size, shape, the error is not lower than the level of foreign, but the co-sets The bearing vibration values, and even produce a different sound, the main problem is the waviness does not control (no standards, no suitable test analysis instruments), while the vibration resistance of the machine tools, grinding wheels, grinding discs, coolant, process parameters are problems; On the other hand to improve the management level, to avoid the bump injuries, scratches, burns at any time machine quality problems. bearing factory in china
    
    For rings, the impact of bearing vibration of the most serious but also channel waviness and surface roughness. For example, the roundness of small and medium-sized deep groove ball bearing inner and outer channel is larger than 2μm, will be bearing vibration significant impact inside and outside the channel waviness greater than 0.7μm, the bearing vibration value increases with the waviness, severe channel knock hurt enable vibration increased by 4dB or more, or even a different sound. china bearing
