I NTN Bearing dealers have a strong technical team, with direct supply channels, with rapid delivery of logistics, with excellent quality imported bearings, model homogeneous and large quantities. As NTN Bearing distributors, in addition to provide more than quality products, but also solve customers in NTN bearing on the issue of selection and the parameters needed technical support and help in the sale of late, if necessary NTN Japan bearings, NTN bearings dealer I can also provide more detailed aspects of after-sales service. 

 NTN bearings to share practical skills spectrum analysis and diagnosis: 
 Now use the data collection is common. However, in practical skills in the note. For small vibrations, bearing little kurtosis, the spectrum of complex vibration signals, in the field is difficult to judge whether the fault condition, we will come back vibration signal acquisition, spread to sophisticated computer analysis. At this point, the first routine analysis, inspection and bearing vibration velocity spectrum is close to the standard kurtosis, and then investigated by power spectrum vibration energy is exceeded, if the power spectrum is not observed in the various frequency components of spectrum. 
 If the entire frequency spectrum corresponding to the frequency times the structure should be focused on the failure to find units; if the frequency scores of times, there is more decimal places frequency, bearing offerings should focus on search frequency, and if so, the existence of the fault bearing ; If not, the exclusion of other causes component failure to be vigilant after, to strengthen monitoring. Actually found that many vibrations are not excessive, and examples of bearing failure occurs. 
 Once the characteristic frequency or close to the bearing bearing characteristic frequency of the spectrum, there should be judged bearing failure, then according to the size of the amplitude can be used for trend analysis or arrange repair. 
 Note: The above are present in the other bearing.
