KOYO method for detection of rolling bearing noise generation

KOYO bearings is allowed in the work of the minor operation noise, if the sound is too large or unusual noise or sound of impact, indicates that the rolling bearing fault.
1, KOYO bearing group production industry in the first-class level in the world, bearing steel strong decides the quality and service life of bearing. Ball and roller rolling element in the roll to operate within also affects the quality of rolling bearing, the bearing can not be the normal operation and has a direct relationship.
2, bearing material, was willing to one of main bearing can not operate normally, now with the metallurgical technology continues to improve, bearing steel is perfection in one's studies. The bearing quality has been greatly improved, and now because of material reasons and make the KOYO bearing the decline in the quality of basic has been resolved. And the choice of lubricant to rolling bearings can not be the normal operation condition is also occur from time to time, is now on the market what are false, including special bearing lubricant, which also contributed to the bearing can not operate normally, it doesn't matter much bearing itself, so heavy brand bearings suffered unrighted wrong, arch-criminal is lubricant.
3, the manufacture of bearings, bearing early cannot run normally due to material
KOYO bearing the causes of noise are more complex, one is the bearings, the mating surface wear. Because of this wear, damaged bearing shells, rolling bearings and shaft meet relationship, causes the axis deviates from the correct location, the shaft noise in high speed motion. When the bearing fatigue, its surface metal flake, also can make the bearing radial clearance increases the noise. In addition, insufficient lubrication of the bearing, the formation of dry friction, as well as bearing broken produces abnormal sound. After bearing wear loose, loose cage damage, also can produce abnormal sound.
