How best to prolong the service life of NTN roller bearing

Many times I have seen some people in the use of NTN bearing life are unused is changed, this is a waste of today, in this let me introduce you to a roller bearing life can make the best method, before we also choose the method of high precision bearings once said, all bearing before installation should be stored in their original packaging. They need to stay clean, no moisture, relatively constant temperature environment. Roller bearing should stay away from dust, water and corrosive chemicals. Imported bearing installation is correct, affects the precision, life and performance. Therefore, the design and assembly department for the installation of the roller bearing to fully research. Hope to work in accordance with the standards for installation. Operation standard project usually is as follows: ( 1) Clean the bearing and the bearing connection parts; ( 2) Check the size of the interrelated parts and finishing; ( 3) Installation; ( 4) After installed NTN bearing inspection; ( 5) Supply of lubricant. Before some problems have been detailed understanding of roller bearing, know in advance (coated with grease Or sealed) Bearing need to be especially careful, because the grease will change after long time of storage density. So when the bearing is used for the first time, there will be a certain degree of rotation noise. Therefore, the NTN bearing on time should be controlled according to the principle of first in first out. We should know is bearing ring rotation surface and the surface roughness of the rolling element is usually a 1/10 microns, such a smooth surface is sensitive to damage caused by pollutants. Lubrication layer between the rotation surface usually is 0. 2 ~ 1 microns, is greater than the lubricant type size particles of impurities are influenced by the excessive rolling rolling element and partial pressure in the bearing steel, eventually lead to permanent material fatigue. Industry experts estimate that premature failure situations 16% of the roller bearing is due to incorrect installation, this is the only ways to maximize big NTN bearing life.
