The choose and buy of NTN bearing and installation method

by：Waxing 2020-09-23

With the wide use of NTN bearings, NTN bearing selection and use of techniques such as technical problem is becoming more and more attention by people, selection of imported bearings and the matters needing attention when using NTN bearing selected profile rolling NTN bearing type, type and size are various. To play the expected performance of mechanical device select the most suitable bearing is very important. For selected NTN bearing, many will need to analyze and study from different angles, the choice of NTN bearing program, there is no special specifications, but generally as follows: ( 1) Master the mechanical device and NTN bearing conditions (such as the use of 2) A clear requirement for NTN bearing ( 3) The type of selected NTN bearing ( 4) Selected NTN bearing configuration mode ( 5) Selected NTN bearing size ( 6) Selected NTN bearing specifications ( 7) Selected NTN bearing installation method NTN bearing after completion of installation on the host, such as the measurement of spindle radial runout, can be found that the each measured value of a certain change; Continuous measurement, can be found that after a certain number of revolution, this change will approximately duplicated. Measure for cyclic rotation accuracy degree of the change, change the approximately duplicated the revolution, on behalf of cyclic rotation accuracy 'cycle', the value of the amplitude changed in quasi cycle, is the cycle rotation accuracy is poor. Such as the proper preload on the spindle, the speed decreases gradually to close to compulsory rotation speed, in order to practice the NTN bearing 'break-in' effect, can improve the circulation of the spindle rotation accuracy.
