I often see some people in the ntn bearing life did not run out to replace the, this is very wasteful to which I introduced a roller bearing life, the past, we alsoonce said, choose the high-precision bearings, all bearings should be kept in their original packaging prior to installation. They need to stay in a clean, moisture free, relatively constant temperature environment. The wheel bearings should be kept away from dust, water and corrosive chemicals.
Installation of imported bearings are correct, and affect the accuracy, longevity, and performance. Therefore, the design and assembly departments roller bearing installation. I hope to be installed in accordance with the operating standards. Operating standards of the project is usually as follows:
(1) cleaning bearings and related parts;
(2) check the connected components of size and finishing;
(3) installation;
(4) ntn bearing is installed after the inspection;
(5) the supply of lubricant.
Previously detailed understanding of some of the problems of the roller bearing, pre-coated with grease (or sealed) bearings need to be especially careful, because the grease will change after a long period of storage density. So that when the bearing for the first time use, there will be some degree of rotational noise. Therefore, this ntn bearing set aside time to be a first in, first out basis to control.
We should be aware of the rotating surface of the bearing ring and rolling element surface roughness is usually 1/10μm such a smooth surface is very sensitive to the damage caused by pollutants.
Lubrication between the rotating surface layer is usually 0.2 ~ 1μm, greater than the lubricant particle size, particle type impurity over rolling element rolling and partial pressure in the bearing steel, will eventually lead to permanent material fatigue. Industry experts estimate that 16% of premature roller bearing failure due to improper installation, which is played by the ntn bearing life large maximum.
