introduction：When using imported medium coarse，If it makes a very harsh sound，That means its the sound of metal sliding from metal to metal。This is right.INAWhen the bearing has no effect，It will not affect the normal operation of the bearing，In this case, there is more or less unnecessary wear and tear，Lower bearing...

introduction：When the inlet bearing is operated under radial load，There are only a few rolling elements inside to bear the load，Formed by elastic contact with the ferrule“spring”The support causes the rolling body to vibrate periodically through the radial load line，The center of the shaft therefore moves vertically up and down or horizontally，Simultaneous noise。This type of vibration is called rolling through vibration，Especially at low speed performance is more obvious。 And its amplitude is related to the imported bearing type、Radial load、The radial clearance is related to the number of rolling elements。Usually the amplitude is small，If the amplitude is large, it will cause harm，To this end, the radial clearance is often reduced or the appropriate pre-load is applied to reduce。 （1）INABearing has been damaged，Should be replaced immediately。 （2）INABearing grease is too low、Excessive or iron filings and other impurities。The capacity of bearing grease shall not exceed the total volume70％，Impurities should be replaced

introduction：When the imported bearing is under radial load and the grease performance is poor，Youll hear it early in operation“click、click”Noise of，This is mainly due to the rolling element after leaving the load zone，Noise caused by sudden acceleration of a rolling element colliding with the cage，This kind of crash is inevitable but with running for a while...
