KOYO outer spherical bearing use daily maintenance for life

KOYO outer spherical bearing cleaning NN is very important. Bearing ring and rotating roller surface roughness is usually 1/10 micron, so smooth surface damage is very sensitive to contamination. Between the rotary surface lubrication is usually 0. 21 microns, larger than the diameter of particle type lubricating oil impurities will be excessive rolling bearing and rolling bearing steel in total stress, eventually lead to permanent fatigue. In addition, up to 10 microns of dust particle size of the external environment, can also result in bearing damage. Therefore, clean dust-free environment for storage and installation of the bearing is very important. KOYO outer spherical bearing for the installation form of vibration motor and other aspects of performance are the effect of a certain change, and from different perspectives to consider also has a certain change, in the form of effect, slowly for all aspects of the installation is also have a certain understanding. Use factors mainly refers to install, use, maintenance, maintenance, repair and so on meets the technical requirements. Installation conditions is one of the primary factor of use factor, bearing is often caused by improper installation of a complete set of change the stress of bearing between various parts, bearing in the abnormal state run and early failure. According to the bearing installation, use, maintenance, maintenance of technical requirements, the operation of the bearing on the load, speed, temperature, vibration, noise and lubrication condition monitoring and inspection, found that abnormal immediately to find the reason, adjustment, so that it is back to normal. In addition, analyze the grease and the surrounding medium, the atmosphere quality inspection is also very important. Internal factors mainly refers to the structure design, manufacturing process and material quality and so on three major factors in determining the quality of bearing. First of all, reasonable structure design and equipped with advanced, just can have a long bearing life. Bearing manufacturing generally go through forging, heat treatment, cutting, grinding and assembly, and multi-channel processing operations. The rationality of the processing technology, advanced, stability will also affect the service life of bearing. Which affects the quality of finished products bearing heat treatment and grinding process, tend to have a more direct relationship with bearing failure. In recent years the study of metamorphic layer of bearings working surface show that the grinding process and is close to the surface quality of the bearing. KOYO outer spherical bearing materials of metallurgical quality were the main factors influencing the premature failure of the rolling bearing. As metallurgy technology, For example, the bearing steel vacuum degassing, etc. ) Progress, raw material quality is improved. Raw material quality factor in the bearing failure analysis share has declined obviously, but it is still one of the main influence factors of bearing failure. Select material adequacy is still bearing failure analysis factors must be considered. KOYO outside the main task of the spherical bearing failure analysis, is based on a lot of background material, analyze data and failure forms, find out the main factors of bearing failure, so that the improvement measures are put forward, prolonging bearing, avoid premature failure of the bearing of the sudden. In order to determine the demolition of bearing, which can be used to clean the bearing after inspection. Carefully check the raceway, raceway surface state, cage wear and bearing clearance and size did not increase the accuracy loss of damage, abnormal. Non separation of small ball bearings, inner ring, with one hand support level, rotate the outer ring to confirm smoothly. KOYO outer spherical bearing isolation form, you can through the rolling body, the outer ring raceway surface inspection. Large bearings, because they can't use hand spin, roll, roll, cage, the outer surface of the frame and other, the importance of bearing high check more carefully, check carefully.
